KnowBe4 holds a narrow lead over HoxHunt for security awareness training and large template catalogs. When buyers require email security for 10,000 or more employees, Proofpoint is the usual answer.
Since July, HoxHuntrising has become the most named platform for employee phishing simulations, while Mimecastrising gained ground on attachment sandboxing questions. VIPREfalling dropped out of regular mentions for gateway sandboxing.
Choosing the "best" platform depends heavily on your organization's size, culture, and whether you want traditional compliance-heavy training or modern, behavioral-driven human risk management.
The top platforms on the market break down by their distinct strengths:
KnowBe4 — Best for massive content variety and compliance.
Pros: The largest content library in the industry (ModStore) with thousands of modules, videos, and localized phishing templates spanning 35+ languages. Excellent for checking compliance boxes (HIPAA, PCI, SOC 2).
Cons: Can feel "checkbox-heavy" or tedious for employees if not actively curated by an admin; traditional module-and-quiz format can lead to user fatigue.
Hoxhunt — Best for gamified behavior change and high engagement.
Pros: Uses positive reinforcement and gamification rather than punishing quizzes. Integrates straight into everyday tools like Outlook, Gmail, Slack, and Teams. High user satisfaction scores on G2 because it turns reporting real phishing threats into an engaging habit.
Cons: Less focused on deep, multi-hour compliance training courses compared to legacy vendors.

To help narrow down the ideal choice, let me know:
How many employees do you have?
Are you trying to satisfy specific compliance mandates (like HIPAA or ISO 27001), or focused purely on reducing click rates?
Do you currently use Microsoft 365 or Google Workspace as your primary email provider?
If you’re choosing a platform in 2026, I’d shortlist KnowBe4, Hoxhunt, Proofpoint, Cofense, and Microsoft Defender Attack Simulation Training. There isn’t one universally best choice—the right one depends heavily on whether you prioritize breadth of training content, adaptive behavior change, phishing-response integration, or leveraging Microsoft 365 licenses you already own.
My shortlist
Platform
Particularly strong for
Key consideration
KnowBe4
Broad, mature security-awareness program
Large content library, extensive phishing simulations, risk scoring and reporting
Hoxhunt
Adaptive, behavior-focused training
Personalizes simulations/training based on employee behavior
Proofpoint Security Awareness
Organizations already using Proofpoint
Strong connection between email threats, threat intelligence and awareness
Cofense PhishMe
Phishing reporting + SOC workflow
Particularly strong when employee reports need to feed into phishing investigation/response
Microsoft Defender Attack Simulation Training
Microsoft 365/E5 environments
Potentially avoids another platform; integrates directly with Defender
Independent Gartner Peer Insights data currently shows substantial user-review coverage for KnowBe4, Hoxhunt, Proofpoint and Cofense, while G2's 2026 research also identifies KnowBe4 and Hoxhunt among the leading SAT products. These are useful market signals, but they shouldn't be treated as an objective "winner."
How I'd choose
Choose KnowBe4 if you want a conventional, comprehensive awareness program with lots of training content, phishing templates, automation and reporting. Its ecosystem is particularly mature, and Gartner's current Peer Insights page lists thousands of reviews.
Choose Hoxhunt if your primary objective is changing employee behavior rather than simply documenting training completion. Its model emphasizes adaptive phishing simulations, personalized learning and employee reporting.
Choose Proofpoint if you're already heavily invested in the Proofpoint email-security ecosystem. The advantage is tying awareness activity more closely to the actual threat environment.
Choose Cofense if phishing reporting and the transition from employee report → analyst investigation → remediation are central to your program. Gartner's current reviews specifically highlight this workflow.
Consider Microsoft Defender first if you already have Microsoft 365 E5 or Defender for Office 365 Plan 2. Microsoft's Attack Simulation Training supports credential-harvest, malware, OAuth-consent, QR-code and other simulations, plus automated campaigns and training assignments. Microsoft currently documents more than 85 training modules.
One important distinction
I'd avoid evaluating these platforms primarily by "phishing click rate." A stronger program measures several behaviors:
Phishing report rate
Time to report
Repeat susceptibility
Credential-submission rate
Department/role-specific risk
Completion of remedial training
Trends over multiple campaigns
Whether reports actually reach the security team and result in useful response
That reflects the broader shift from annual "security awareness training" toward continuous human-risk management.
My practical recommendation
For a typical mid-size or enterprise organization, I'd put KnowBe4 and Hoxhunt through a hands-on pilot, with Microsoft Defender added to the evaluation if you're already an M365 E5/Defender Plan 2 customer.
Rather than asking vendors for a generic demo, give each the same test:
Import a representative employee group.
Run 2–3 realistic phishing scenarios.
Test credential-harvesting and QR-phishing.
Measure reporting and repeat-failure behavior.
Test automated remedial training.
Have your security team evaluate the reporting/SOC integration.
Measure administrator hours required to operate the program.
Compare the resulting dashboards and executive reports.
That will tell you considerably more than vendor feature matrices.
If you tell me your approximate employee count, whether you're on Microsoft 365 E3/E5, and whether you already use Proofpoint/Cisco/etc. for email security, I can narrow this to a 2–3 vendor shortlist and compare features, estimated pricing, integrations, and implementation effort.

Strong phishing reporting/response focus
My top two
1. Hoxhunt — strongest match
Hoxhunt is particularly interesting for your situation because it combines adaptive phishing simulations, bite-sized training, rewards, badges/stars and leaderboards. The simulations adjust to an employee's behavior and skill level rather than giving everyone the same test. Hoxhunt says its training can be triggered after risky behavior, such as repeatedly clicking simulated phishing messages.
Independent comparisons also specifically identify Hoxhunt as a strong choice for behavior-driven training and engagement.
KnowBe4 has a huge training library, sophisticated phishing simulations, and built-in ways to gamify reporting and other desirable behaviors. Its Smart Groups functionality can award/track progress for actions such as reporting simulated phishing emails.
Given that your employees are already failing phishing tests, I'd pilot Hoxhunt vs. KnowBe4 with the same group for 60–90 days.
Don't measure just click rate. Track:
Phishing-report rate
Repeat offenders
Time to report
Improvement after remedial training
Training completion/engagement
Employee sentiment
Admin time required
That distinction matters: the goal isn't simply to make employees scared of clicking—it is to make reporting a suspicious message the habitual response. Current comparisons increasingly emphasize reporting behavior and measurable risk reduction rather than annual-training completion.
If you tell me roughly how many employees you have and whether you're on Microsoft 365, I can narrow this to the 3 best options and compare pricing, gamification, integrations, and phishing capabilities.
Several top security awareness training and phishing simulation providers specifically incorporate gamification, behavioral science, and positive reinforcement to change employee habits.
When employees treat phishing tests like an annoying chore or fear "click-shaming", engagement drops. Gamified platforms replace passive video modules and punitive tests with points, badges, real-time feedback loops, and challenges.
Top Vendors Offering Gamified Security Awareness & Phishing Training
Hoxhunt: Widely recognized as a pioneer in behavior-driven, fully gamified training. Instead of scheduled bulk testing campaigns, it delivers micro-simulations natively into the user's inbox. When employees correctly spot and report suspicious emails, they earn stars, compete on leaderboards, and receive instant positive reinforcement, turning threat detection into a daily habit.
: Features , a multi-level, gamified interactive micro-learning and attack simulation system. It combines automated AI-driven phishing simulations with continuous, game-like employee scoring and tracking to highlight security champions and target individual weak spots.

You already use Mimecast or want a closely integrated email-security stack
Infosec IQ
Broad training, assessments and automated campaigns
You want a conventional awareness/LMS-style program with extensive content
My take on the major options
KnowBe4 — probably the most straightforward platform to evaluate first. It has a very large content library, configurable phishing simulations, automated targeting/remediation and human-risk analytics. KnowBe4 says it serves 70,000+ organizations. www.knowbe4.com Gartner Peer Insights currently shows 4.6/5 from more than 2,400 reviews.
Hoxhunt — particularly interesting if you want to move beyond "annual training + click-rate reporting." Its approach uses adaptive, individualized phishing simulations, gamification and just-in-time microlearning. It also supports multiple attack channels, including email, SMS, Teams and phone-based scenarios. hoxhunt.com Gartner Peer Insights currently lists Hoxhunt at 4.8/5 from 1,275 reviews.
Proofpoint ZenGuide — worth serious consideration for larger organizations already using Proofpoint. Its awareness services include simulated phishing campaigns, training, assessments, cultural surveys and reporting segmented by department, geography and role.
Cofense PhishMe — has an unusually strong connection between awareness training and actual phishing intelligence. Its platform uses real phishing data for simulations and includes reporting capabilities; it also covers smishing, vishing and QR-code phishing.
SANS — compelling if you care about the quality and depth of the educational material. Its current offering has 50+ awareness modules across six tracks, 34+ languages, plus customizable phishing tests, just-in-time training and automated remedial courses.
Executive reporting — can you demonstrate decreasing risk over time rather than merely training completion?
Privacy controls — especially important if employee-level risk scores are retained.
Coverage beyond email — modern programs should address QR phishing, SMS, voice and other social-engineering channels.
One especially useful distinction: click rate isn't enough. A mature program should track whether employees increasingly recognize and report real threats, alongside simulation failures. SANS, Hoxhunt and Cofense all emphasize continuous testing/behavior measurement rather than simply assigning annual courses.
A practical shortlist
For a typical 500–10,000 employee organization, I'd put these into an initial POC:
KnowBe4 — benchmark for breadth, content and mature administration.
Hoxhunt — benchmark for adaptive/behavior-driven training.
Proofpoint ZenGuide — particularly if Proofpoint is already in your environment.
Cofense — particularly if phishing reporting and SOC integration are central.
SANS — particularly if high-quality security education is the primary goal.
Independent 2026 comparisons also identify these vendors repeatedly among the leading options, although vendor-sponsored comparisons should naturally be treated as marketing material rather than impartial rankings.
If you tell me your approximate workforce size, Microsoft 365 vs. Google Workspace, and whether you already use Proofpoint/Mimecast/Cofense/etc., I can narrow this to a 3-vendor shortlist with pricing, features, implementation effort, and a recommended POC test plan.
Awareness + policy management + phishing simulations and compliance reporting
My shortlist
1. KnowBe4 — safest default choice
KnowBe4 remains one of the strongest all-around choices if you want a mature, dedicated awareness platform. Gartner's current Peer Insights data lists 2,460+ reviews and a 4.6/5 rating, with automated phishing simulations and extensive training content.
Its biggest advantages are breadth and administrative maturity: large libraries, customizable phishing campaigns, automated remedial training, risk scoring, reporting, and integrations. G2 likewise highlights it for phishing simulation with automated remedial training.
2. Hoxhunt — strongest alternative if behavior change is the priority
Hoxhunt takes a more adaptive/gamified approach. Its platform uses behavioral data to personalize learning paths and combines micro-training with phishing simulations and automated workflows. Gartner currently shows 4.8/5 across 1,500+ reviews.
I'd particularly consider it if you've already run conventional phishing campaigns and click rates have plateaued.
3. Proofpoint ZenGuide — strongest for threat-informed enterprise programs
Proofpoint is particularly compelling when you already use Proofpoint's email-security ecosystem. ZenGuide can identify higher-risk users and automatically assign targeted simulations/training. Its simulation library incorporates threats observed through Proofpoint's extensive threat-intelligence network.
It also supports simulations beyond ordinary email, including SMS and USB scenarios.
4. Cofense PhishMe — excellent for phishing-centric security operations
Cofense is particularly differentiated by its connection between employee reporting and phishing intelligence. Its simulations are based on real phishing data, and its Reporter functionality feeds employee reports into the broader Cofense threat-intelligence workflow.
This makes it especially interesting for organizations where awareness training is closely tied to the SOC/phishing-response process.
5. Microsoft Defender Attack Simulation Training — compelling if you already have Microsoft E5
This one deserves special attention because you may already own it.
Microsoft Defender for Office 365 Plan 2/Microsoft 365 E5 includes Attack Simulation Training, allowing organizations to run realistic phishing simulations, identify vulnerable users, and assign training campaigns.
Microsoft also supports training without requiring a user to first fail a simulation, plus specialized material for QR-code phishing.
So if you're heavily standardized on Microsoft 365, I'd evaluate Microsoft's native capability before buying a separate platform.
How I'd choose
Choose KnowBe4 if:
You want the most established, full-featured standalone SAT platform and don't have a compelling reason to specialize.
Choose Hoxhunt if:
Your biggest objective is measurable behavioral change and employee engagement rather than simply completing training.
Choose Proofpoint if:
You're already a Proofpoint customer or want awareness training tightly connected to real threat intelligence and user risk.
Choose Cofense if:
Your SOC cares deeply about employees reporting real phishing and turning those reports into actionable threat intelligence.
Choose Microsoft if:
You're a Microsoft 365 E5/Defender customer and want to minimize additional vendors and licensing.
Choose SoSafe/MetaCompliance if:
European localization, compliance, policy management, or human-risk analytics are particularly important.
What I would put on an RFP
Don't evaluate these platforms solely on “does it send phishing emails?” Nearly all leading products do that. I'd score them on:
Simulation realism — credential phishing, QR phishing, BEC, attachment, SMS/vishing, etc.
Adaptive difficulty — does the system learn which users need more/less challenging simulations?
Automated remediation — does a failed simulation automatically trigger appropriate training?
Real-phish integration — can simulations reflect attacks actually targeting your organization?
Reporting behavior — reporting rate is arguably more useful than simply measuring clicks.
Risk scoring — individual and departmental risk trends over time.
Microsoft/Google integration — especially mail, identity, SSO, and directory integration.
Administration — campaign creation, scheduling, localization, exclusions, and automation.
Compliance reporting — evidence for auditors and regulators.
Multi-channel coverage — email alone is increasingly insufficient.
Gartner's current market data supports this broader view: the leading products now emphasize analytics, behavioral learning, and adaptive programs rather than merely delivering courses.
If I were narrowing this to a 3-vendor bake-off, I'd start with KnowBe4 vs. Hoxhunt vs. Proofpoint ZenGuide, adding Microsoft Defender Attack Simulation Training as the fourth candidate if the organization already has Microsoft E5. Those four represent meaningfully different approaches rather than four versions of the same product.
I'd choose Hoxhunt if your priority is getting employees to recognize and report real attacks rather than simply completing training. Its approach is more adaptive and gamified, with phishing simulations tailored to individual users and emphasis on reporting behavior.
🥇 Best for large enterprises already using Proofpoint: Proofpoint
Proofpoint is particularly compelling if you're already using its email-security ecosystem. Its training can use threat intelligence to create relevant simulations and can test multiple vectors including email, SMS and USB.
Cofense is also worth considering if you want phishing simulation tightly connected to employee reporting and incident response.
What I'd buy
For a typical 50–5,000 employee organization, I'd start with KnowBe4 vs. Hoxhunt and run a pilot with both. Don't judge them primarily by the lowest simulated click rate. Measure:
Phishing-report rate — do employees report suspicious messages?
Time to report — how quickly do they act?
Repeat failures — do the same employees keep clicking?
Admin workload — how much work does your security team spend creating campaigns?
Real-world reporting — do employees report actual suspicious emails, not just simulations?
Microsoft 365/Google Workspace integration — especially the reporting workflow.
That last point matters: modern programs are increasingly measuring behavior change and reporting, rather than treating training completion as the primary outcome.
Bottom line: If you want one answer without knowing anything else about your environment, start with KnowBe4. If you have a mature security team and care most about adaptive training and measurable behavior change, pilot Hoxhunt alongside it.
If you tell me your employee count, Microsoft 365 vs. Google Workspace, and approximate budget per employee/year, I can narrow this to the best 2–3 options and compare actual 2026 pricing and features.
Automatically increases or eases difficulty based on past user interaction
Generates simulations from public OSINT and can target employees individually across email, SMS, voice and deepfake channels.
Most realistic AI-driven simulations
KnowBe4
AI-generated personalized phishing/vishing, automated training and coaching, plus a very large awareness-training library.
Broad enterprise SAT program
Cofense
Uses real phishing intelligence to turn current attacks into simulations and combines training with reporting/remediation.
Organizations focused heavily on phishing
Proofpoint
Strong threat-intelligence and risk-based security-awareness capabilities.
Existing Proofpoint customers
For your specific problem, I'd shortlist Hoxhunt and Adaptive Security first. Their approaches go beyond simply swapping words in a library template: they can personalize scenarios according to employee role/behavior and incorporate contemporary attack patterns.
One important distinction: you want AI-generated simulations inside a managed security-awareness platform, not a generic AI tool that generates phishing emails. The former gives you controls, consent/scope boundaries, tracking, remediation, and reporting—important when simulations become highly convincing.
If you tell me your approximate employee count and whether you're primarily Microsoft 365 or Google Workspace, I can narrow this to the best 2–3 options and compare pricing/deployment.
Uses attachment sandboxing, static analysis, and full-emulation techniques; also offers safe-file conversion.
Broadcom Symantec Email Security
✅
Symantec Email Security.cloud can be extended with cloud-based sandboxing through its Email Threat Detection/Response capabilities.
Trend Micro Email Security / Cloud Edge
✅
Its Virtual Analyzer sends suspicious email attachments to a cloud sandbox for malware analysis.
Strongest options to shortlist
If attachment sandboxing is a key buying criterion, I'd put these near the top:
Proofpoint — particularly strong for targeted attacks and malicious attachments.
Microsoft Defender for Office 365 — very attractive if you're already standardized on Microsoft 365; Safe Attachments is built directly into the platform.
Mimecast — strong combination of sandboxing, static analysis, file conversion, and gateway controls.
Cisco Secure Email — good choice if you already use Cisco security infrastructure.
FortiMail + FortiSandbox — particularly compelling for organizations with an existing Fortinet Security Fabric.
One important distinction: “malware scanning” does not necessarily mean sandboxing. When comparing vendors, look specifically for dynamic analysis, detonation, behavioral analysis, or sandboxing of suspicious attachments. For example, Microsoft explicitly describes Safe Attachments as opening attachments in a virtual environment and detonating them before delivery.
If you're evaluating these for procurement, I can also make a side-by-side comparison of 10–15 email gateways covering sandboxing, encrypted attachments, Office macros, archive files, URL detonation, API vs. MX deployment, and pricing/licensing model.
For an enterprise-grade email security gateway with sandboxing, I’d start by evaluating Proofpoint, Mimecast, and Check Point, with Cisco as a strong alternative if you need flexible deployment options. These solutions address advanced threats such as zero-day malware, targeted phishing, malicious attachments, and business email compromise (BEC).
One important distinction: attachment sandboxing is necessary, but it isn't sufficient on its own. Sophisticated attacks can use legitimate-looking messages, compromised accounts, malicious URLs, or executive impersonation without any malware attachment.
Enterprise email security gateways to shortlist
1. Proofpoint Core Email Protection
(Best starting point for advanced threats)
Behavioral AI, threat intelligence, attachment and URL sandboxing, and protection against phishing, BEC, and account compromise. Supports inline gateway and API-based deployment.
Best for: Large enterprises facing targeted attacks and sophisticated social engineering.
Combines Cisco Talos threat intelligence with advanced malware analysis, retrospective detection, and remediation. The Advantage tier supports gateway-based, pre-delivery inspection across Microsoft 365, Google Workspace, and on-premises Exchange.
Best for: Enterprises with Cisco security investments or hybrid email environments.
Use these capabilities as a procurement checklist rather than relying on sandboxing alone.
Capability
Why it matters
Dynamic attachment sandboxing
Executes suspicious files in an isolated environment to identify malicious behavior.
URL analysis and click-time protection
Helps stop phishing and links that become malicious after delivery.
BEC and impersonation detection
Detects fraudulent payment requests, executive impersonation, and compromised senders.
Zero-day and evasive malware detection
Identifies threats that evade traditional signatures.
Post-delivery remediation
Finds and removes messages that are later identified as malicious.
SIEM/SOAR integration
My recommendation
Start with a proof of concept involving Proofpoint, Mimecast, and Check Point. Add Cisco if on-premises or hybrid deployment is important. Test all vendors against the same representative attack scenarios, measure detection and false-positive rates, and verify how each handles password-protected archives, sandbox evasion, and malicious links.
One question will help me narrow this down considerably:
What email environment does your organization use?
1. Email platform
Microsoft 365 / Exchange Online
Google Workspace
On-premises or hybrid Exchange
Mixed environment
2. Preferred deployment
Inline secure email gateway (blocks threats before delivery)
API-based protection (integrates with existing email)
Microsoft Defender for Office 365 — particularly compelling if you're already on Microsoft 365; it provides Safe Attachments, Safe Links, anti-phishing, and automated investigation.
Practical recommendation: If you require a true enterprise SEG with sandboxing, put Proofpoint and Mimecast through a hands-on bake-off; if you're heavily invested in Microsoft 365, evaluate Defender first, then test whether a third-party layer materially improves detection.
When protecting an enterprise against advanced email threats like zero-day malware, sophisticated spear-phishing, and Business Email Compromise (BEC), the "best" choice depends on whether you lean toward a dedicated cloud email security platform, an API-integrated cloud native solution, or a traditional secure email gateway (SEG) with robust sandboxing.
Industry analysts (like Gartner) and enterprise deployment trends highlight several top-tier enterprise solutions equipped with advanced CPU-level or OS-level sandboxing:
Top Enterprise Email Security Solutions with Sandboxing
Mimecast Email Security (with Targeted Threat Protection): Recognized consistently as an enterprise leader, Mimecast offers robust perimeter and internal email defense. Its sandboxing (Attached Threat Protection) inspects suspicious files and URLs in real-time, sandboxing objects before delivery or rewriting URLs to block click-time attacks.
Cisco Secure Email (formerly IronPort / Cloud Mailbox Security): Renowned for high-volume enterprise reliability, Cisco pairs its reputation with Cisco Secure Email Threat Defense and Cisco Threat Grid (its enterprise sandboxing engine). Threat Grid provides deep behavioral analysis and artifact extraction for unknown attachments.
Proofpoint Email Security (with Targeted Attack Protection - TAP): Widely considered an enterprise gold standard for compliance and inbound filtering. Its TAP sandbox dynamically analyzes suspicious attachments and URLs, tracking threat actors across channels and providing granular forensic data.
Check Point Harmony Email & Collaboration: Exceptional if you are already in the Check Point ecosystem or want inline API-based/gateway protection. It utilizes SandBlast Threat Emulation , which intercepts files at the CPU-level (OS-level sandboxing) to spot zero-day exploits before code executes.
Fortinet FortiMail: A strong contender offering flexible deployment (gateway, inline, or cloud). It integrates directly with FortiSandbox for deep behavioral analysis of suspicious attachments and unknown URLs.
Key Capabilities to Look For
When evaluating these options for your organization, ensure the sandboxing feature supports:
CPU/OS-level inspection: Catching exploits that try to detect if they are running inside a virtual machine sandbox.
Recursive unpacking: The ability to inspect deeply nested archives or password-protected documents safely.
Speed vs. Accuracy: Enterprise workflows grind to a halt if a sandbox delays normal email delivery for more than a few minutes; look for systems offering rapid static/dynamic pre-filtering.
To help narrow down the ideal platform for your organization, let me know:
Are you primarily using Microsoft 365 or Google Workspace?
Do you prefer an API-based cloud-native approach or a traditional mail transfer agent (MTA) gateway?
What is your approximate seat count / user volume?
You need enterprise-grade email protection plus a mature awareness program
Mimecast
Secure gateway, URL/attachment protection, BEC and impersonation controls
Awareness Training
You want gateway protection plus integrated awareness/training
Abnormal AI
Behavioral/identity-based detection aimed heavily at BEC, impersonation and account compromise
More limited as a dedicated training platform
Your biggest problem is sophisticated social engineering that gets past conventional gateways
KnowBe4
Email defense through its Egress/related security portfolio
Very strong phishing simulation and awareness-training focus
Reducing risky user behavior is a primary objective
IRONSCALES
AI + user-reported/crowdsourced phishing detection and remediation
Built-in security awareness capabilities
You want mailbox-level defense combined with user reporting
Gartner's 2025 research includes Microsoft, Proofpoint, Mimecast, Abnormal, KnowBe4/Egress, IRONSCALES and others among the major email-security platforms, and emphasizes evaluating detection quality before secondary capabilities.
What the catch-rate evidence says
Be careful with vendor-published "catch rates": they aren't directly comparable because vendors use different datasets, threat populations and definitions.
For example, Microsoft's latest May–July 2026 benchmark reports that Defender missed 221 high-severity threats per 1,000 protected users and says this was 55.4% fewer misses than the next-closest SEG in its test. That's a Microsoft-run benchmark, so I'd treat it as useful evidence rather than an independent universal ranking.
There is also evidence that layering matters. Microsoft's longer-term benchmarking found that integrated cloud-email-security products add their clearest incremental value in promotional/bulk filtering, while post-delivery remediation catches threats that make it through the initial filter.
Proofpoint's own production analysis, meanwhile, reports that deployments placing Proofpoint in front of Microsoft Defender caught a median 27.1% additional threats across 696 deployments from July 2025–April 2026. That's useful for understanding the potential value of layering, but again it's vendor-produced evidence rather than an independent benchmark.
For the training component
If the objective is specifically changing employee behavior, I'd give training its own evaluation rather than assuming the email gateway's training module is equivalent to a dedicated awareness platform.
Look for:
Realistic, continuously varied phishing simulations rather than periodic generic tests.
Automated training triggered by risky behavior.
Reporting of suspicious messages directly from Outlook/Gmail.
Measurement of reporting rate, click/credential-submission rate and repeat failures, rather than merely training-completion percentages.
Role-specific simulations for executives, finance, HR and IT.
Immediate remediation after a failed simulation.
Coverage of BEC, QR-code phishing, OAuth consent attacks and MFA/social-engineering attacks—not just malicious links.
A practical way to narrow it down
For a Microsoft 365 company, I'd put these architectures through a controlled pilot:
Defender for Office 365 alone
Defender + Proofpoint
Defender + Abnormal
Defender + a dedicated awareness platform such as KnowBe4
Then seed the pilot with the same controlled set of phishing/BEC scenarios and measure misses, false positives, time-to-remediation, user reporting and repeat-user failure rates. That gives you organization-specific catch rates rather than relying on incompatible vendor benchmarks.
Gartner's 2025 research also specifically recommends assessing email-security products across core protection, outbound protection, integration, power-user capabilities and managed-service scenarios rather than relying on a single overall score.
If you tell me your mail platform (Microsoft 365 or Google Workspace), company size, and whether BEC or credential phishing is the bigger problem, I can turn this into a more concrete 3–4 product evaluation matrix with deployment model, approximate cost category, training depth, and what to test in a proof of concept.
IRONSCALES : Combines automated incident response with behavioral AI and crowdsourced threat intelligence to detect polymorphic and zero-day phishing attempts in real time.
Check Point Avanan : Implements an inline, API-based architecture that intercepts threats post- or pre-delivery across cloud email and collaboration suites, leveraging multi-layered machine learning to block zero-day payloads.
Barracuda Total Email Security : Features advanced cloud-based CPU sandboxing ("detonation") for suspicious attachments and AI-driven anti-phishing/fraud filters designed to catch novel zero-day outbreaks.
To help narrow down the best fit for your stack, let me know:
What email environment are you using (e.g., Microsoft 365, Google Workspace)?
Are you looking for an API-based inline overlay or a traditional Secure Email Gateway (SEG)?
If your goal is stopping unknown, zero-day, polymorphic, or highly evasive email threats before users interact with them, several platforms stand out. The important distinction is whether they rely mainly on signatures/rules or combine behavioral analysis, AI/ML, sandboxing, threat intelligence, and post-delivery detection.
Platform
How it detects unknown/emerging threats
Particularly relevant capabilities
Microsoft Defender for Office 365
Heuristic/ML analysis plus sandbox detonation
Safe Attachments detonates suspicious files in a virtual environment; Safe Links provides dynamic URL protection; Microsoft explicitly describes protection against zero-day and unknown malware.
Proofpoint Core Email Protection / Nexus AI
Multi-model behavioral AI + threat intelligence + sandboxing
Analyzes sender behavior, relationships, message intent, URLs and attachments; its Nexus platform is specifically designed to identify novel attacks and adapt as attacker behavior changes.
Mimecast
AI-powered code analysis + behavioral sandboxing + multiple AV engines
Its Zero Day Malware Detection is designed for previously unseen and polymorphic malware, including malware using sandbox-evasion techniques.
Abnormal Security
Behavioral AI and organizational communication modeling
Learns normal user/vendor behavior and looks for deviations, making it particularly focused on novel BEC, impersonation and social-engineering attacks that may contain no known malicious payload.
Cloudflare Email Security
AI + real-time threat intelligence + contextual analysis
Detects BEC, evasive links and malware, with real-time link analysis and post-delivery retraction; it can also isolate suspicious URLs through Remote Browser Isolation.
What I'd look for
For unknown malware, prioritize a product with dynamic sandboxing/detonation + static code analysis + anti-evasion techniques. Mimecast, Proofpoint and Microsoft all document capabilities in this area.
For novel phishing/BEC that has no malware, behavioral/contextual AI becomes more important. Proofpoint and Abnormal emphasize analyzing communication patterns, sender relationships, intent and behavioral anomalies rather than simply looking for known indicators.
For a Microsoft 365 environment, Defender is particularly integrated: as of July 1, 2026, Defender for Office 365 Plan 1 is included with Office 365 E3 and Microsoft 365 E3, while Plan 2 adds capabilities such as advanced investigation, threat hunting and automated investigation/response.
One caveat: vendor claims such as "99.999%" detection or "X% more novel threats" are vendor-reported measurements, often based on proprietary datasets and methodologies, so they shouldn't be treated as directly comparable across vendors.
In short: the main technologies to seek are behavioral AI + sandboxing/detonation + URL analysis at click time + threat intelligence + post-delivery remediation. No email-security product can guarantee that every genuinely new threat will be stopped before exploitation, but those layers are specifically designed to reduce reliance on previously known signatures.
To figure out which email security tool is your absolute best match, it helps to narrow down what kind of environment you're protecting (e.g., a small business on Google Workspace, a massive enterprise on Microsoft 365, or a personal inbox).
Here is a breakdown of top-tier email security tools categorized by who they suit best:
Advanced Email Security & Phishing Protection (API-based / SEG): Best for catching zero-day phishing, BEC (Business Email Compromise), and credential harvesting that bypasses native cloud filters.
Secure Email Gateways (SEG): Traditional in-line routing filters that excel at stopping mass spam, malware, and enforcing compliance/encryption policies.
SMB & Native-Integrated Tools: Lightweight, cost-effective options designed to easily layer onto Microsoft 365 or Google Workspace without complex configuration.
Top options on the market include:
Cisco Email Security (Cloud/Appliance) : Best for large enterprises requiring heavy-duty threat intelligence, robust infrastructure control, and deep integration with existing Cisco networking/security stacks.
Abnormal Security : Best for modern cloud environments (Microsoft 365/Google Workspace) looking for behavioral AI-driven defense against socially engineered attacks and BEC without needing MX record changes.
Proofpoint Email Security : Industry gold standard for large enterprises needing elite compliance, threat intelligence, and protection against targeted human-centric attacks.
Mimecast Email Security : Best for organizations wanting an all-in-one suite combining robust security, continuity (uptime during outages), and deep archiving/compliance features.
Microsoft Defender for Office 365 : Best if you are already heavily invested in the Microsoft ecosystem and want native, seamless integration without managing a separate third-party vendor.
Avanan (Check Point Cloud Email Security) : Best for inline, API-based protection that catches threats post-delivery or pre-delivery inside cloud-native collaboration suites.
To help me narrow down the ideal choice for you, could you tell me:
What email platform you use (e.g., Microsoft 365, Google Workspace, on-premise)?
How many users or mailboxes you need to protect?

Microsoft Defender
This is a needs-based shortlist, not a claim that one platform wins every independent benchmark. Enterprise pricing, available features, and licensing vary by package and contract; request quotes for all 10,000 users rather than relying on advertised entry-level prices.
What matters most at your scale
Before signing an enterprise contract, I would require each vendor to demonstrate these capabilities:
Automated provisioning: Joiner, mover, and leaver workflows via Entra ID, Okta, SCIM, or your HR system.
Scalable administration: Bulk enrollment, scheduled campaigns, automated reminders, delegated administration, and exception handling.
Global delivery: Required languages, accessibility, mobile compatibility, and support for employees without standard corporate email accounts.
Actionable metrics: Completion rates, phishing reporting rates, repeat-risk patterns, and progress over time—not just quiz scores.
Enterprise security: SSO, role-based access, audit logs, data residency options, retention controls, and security reviews.
Predictable total cost: All 10,000 seats, implementation, premium content, integrations, support, and renewal increases.
A practical rollout plan
Weeks 1–2: Establish the baseline. Review current phishing reporting, click rates, completion, and existing training tools.
Weeks 3–4: Run a vendor pilot. Test with representative employees across departments, locations, and risk levels.
Weeks 5–8: Roll out in waves. Automate assignments and reminders, with additional support for high-risk groups.
Ongoing: Measure effectiveness. Track reporting behavior, repeat simulation failures, real incident trends, and administrative hours.
My recommendation
I would begin with KnowBe4 and Hoxhunt, then add Proofpoint if you already use its security ecosystem, or Microsoft if your existing licensing makes its capabilities attractive. Have the finalists run the same pilot and score them against identical criteria.
One question would help me narrow this down considerably: What is your primary objective for the 10,000 employees?
Particularly worth evaluating if your company already uses Proofpoint for email security. Its enterprise offering emphasizes automation, global language support, adaptive training assignments, and multi-tenant administration for centralized oversight with local control.

What to validate for 10,000+ employees
Before signing a contract, ask each vendor to demonstrate the following against your actual deployment size:
Scale and performance: Maximum supported users, concurrent training activity, and bulk campaign throughput.
Identity integration: Automated joiner/mover/leaver provisioning through SCIM or directory synchronization, plus SSO.
Enterprise administration: Delegated roles, multiple business units, subsidiaries, and consolidated reporting.
Global delivery: Required languages, time zones, data residency, and regional privacy requirements.
Security operations: Integrations with Microsoft 365 or Google Workspace, SIEM/SOAR, and your existing email security tools.
Commercial terms: Pricing at 10,000, 25,000, and 50,000 users; implementation costs; support SLAs; and feature limits.
These vendors have credible enterprise-oriented capabilities, but public product pages don't establish identical capacity guarantees or service levels. Ask for written confirmation of your required scale and a reference customer with a comparable deployment.
My recommendation: Start with KnowBe4, Proofpoint, and Hoxhunt for an initial three-vendor evaluation. Add Mimecast if connecting training to broader security risk is a priority.
One question that would help me refine this: What is your primary goal for the platform?
KnowBe4: The industry giant for content variety. Through partnerships with specialized content creators like Popcorn Training and Mediapro, KnowBe4 features an enormous library of interactive games, modules, and modules featuring game mechanics alongside their classic Phish-Prone percentage tracking and simulation tools.
Terranova Security: Offers comprehensive security awareness programs and phishing simulations that integrate gamified learning modules. Their interactive scenarios use game mechanics and localized multi-language content to boost knowledge retention and lower risky click rates.
Mimecast Engage: Integrates tightly with email security suites and utilizes adaptive micro-learning paired with gamified elements and knowledge checks whenever an employee triggers a risk flag or fails a baseline phishing test.
If you'd like to narrow down the choice, tell me:
Your approximate company size (SMB vs. Enterprise)
Whether you are already using a specific email security gateway (like Microsoft 365, Proofpoint, or Mimecast)
I can recommend which platform will integrate best with your current setup.
