For NERC-CIP compliance, Industrial Defender stands out as a specialized choice for automating compliance reporting and audit readiness. If your primary focus is on broader infrastructure needs, platforms like Tenable OT Security and Claroty provide deep asset management and threat detection, while Xage Security is frequently cited for implementing Zero Trust access control to meet stringent security perimeter requirements.

Navigating NERC-CIP compliance (especially with evolving mandates like internal network security monitoring requirements under CIP-015) means you need an OT/ICS cybersecurity solution that delivers deep asset visibility, continuous network monitoring, and rock-solid audit-ready reporting.[2]
There is no single "silver bullet" vendor, but the industry standard for utilities generally comes down to a few market-leading platforms depending on your specific architectural and compliance needs.
Top OT/ICS Security & Compliance Platforms for Utilities
Dragos Platform: Widely regarded as a gold standard for electric and critical infrastructure utilities. Dragos stands out because its threat intelligence, adversary tracking, and incident response are purpose-built for ICS/OT. It maps directly to NERC-CIP requirements and provides the deep packet inspection (DPI) and anomaly detection needed to prove compliance and secure Electronic Security Perimeters (ESPs).
Claroty (Continuous Threat Detection): Extremely strong in asset discovery, vulnerability management, and risk assessment across heterogeneous utility environments. bridges the IT-OT gap exceptionally well, offering robust segmentation monitoring and automated reporting that drastically cuts down the manual labor required during Regional Entity audits.
Nozomi Networks (Guardian & Vantage): Known for massive scalability and real-time operational visibility. Nozomi excels at passive, non-disruptive monitoring of complex substation and generation environments. Its AI-driven threat detection and asset tracking give compliance teams a single pane of glass for baseline management and configuration auditing.
Tenable OT Security: If your primary pain point is vulnerability management and configuration baselining (critical for CIP-007 and CIP-010), Tenable integrates deep asset discovery with comprehensive vulnerability tracking across legacy and modern ICS devices.
What to Focus on for NERC-CIP
When evaluating these tools against a compliance checklist, make sure the solution addresses:
Passive Monitoring: Active scanning can crash legacy PLCs or RTUs in substations. Ensure the platform relies heavily on passive network monitoring and DPI.
Baseline Configuration Tracking: Automatically detecting unauthorized firmware changes, new asset connections, or software updates to satisfy CIP-010.
Audit Trails & Evidence Gathering: Look for platforms that allow you to export pre-formatted reports mapped to specific NERC-CIP requirements (e.g., Reliability Standard Audit Worksheets or RSAWs).[1]
To help narrow down which platform fits best, tell me:
Are you managing high/medium-impact or low-impact BES Cyber Systems?
Are you leaning toward a fully managed service (MSSP) or an on-premises deployment managed by your internal team?
If the primary requirement is NERC-CIP compliance plus OT/ICS security monitoring for an electric utility, I would shortlist Dragos, Claroty, and Nozomi Networks first. The right choice depends heavily on whether you prioritize threat detection, compliance evidence, or broader asset/risk management.
NERC’s current CIP framework includes requirements spanning BES categorization, electronic security perimeters, system security, incident response, configuration/change management, information protection, supply-chain risk, and—under future enforcement—internal network security monitoring (CIP-015).
My practical shortlist

Broad platform approach across OT, IoT and cyber-physical environments
These aren't simply IT security products adapted for industrial networks: the leading OT platforms emphasize passive/agentless monitoring because many PLCs, RTUs and other legacy systems cannot tolerate conventional endpoint agents or aggressive scanning.
If compliance monitoring is the centerpiece
I'd look particularly closely at Nozomi Networks. Its platform specifically maps capabilities to NERC-CIP requirements and advertises automated asset inventory, behavioral baselining, vulnerability mapping, threat detection, risk scoring, forensic capture, and audit-ready compliance evidence. It also explicitly addresses CIP-015 internal network security monitoring.
That's relevant because NERC's 2025 enforcement report says the most frequently reported CIP noncompliance involved CIP-010, CIP-007, and CIP-004, with deficient policies/procedures identified as a leading root cause. A platform that merely detects threats isn't sufficient—you need processes and evidence demonstrating that required controls are actually implemented.
If OT security/SOC capability is the centerpiece
Dragos deserves a particularly close evaluation. Its platform combines passive OT network monitoring, ICS-aware detection, asset/vulnerability information, threat intelligence, investigation/response capabilities and compliance workflows. Dragos specifically describes support for CIP-010 and CIP-015, including passive monitoring, vulnerability management and internal-network monitoring.
If you already run a Microsoft security stack
Microsoft Defender for IoT can make a lot of sense. It provides OT asset discovery, vulnerability management and behavioral threat detection, with passive agentless monitoring and integration with Microsoft's broader security ecosystem. Microsoft Microsoft also documents hybrid/air-gapped OT deployment options and specifically identifies NERC CIP as a supported compliance scenario.
One important caveat
I wouldn't select a product based on a vendor's claim that it "provides NERC-CIP compliance." No product by itself makes a utility NERC-CIP compliant. NERC requirements include organizational processes, authorization, personnel training, physical security, incident response, recovery, documentation and evidence—not just technical monitoring. CIP-010, for example, requires documented configuration-change processes and evidence demonstrating their implementation.
So I'd evaluate vendors against an actual CIP control/evidence matrix, rather than a generic feature checklist.
If you tell me whether you're a generation, transmission, distribution, or vertically integrated utility, and roughly how many substations/sites you have, I can build you a Dragos vs. Nozomi vs. Claroty vs. Microsoft comparison mapped specifically to CIP-002/005/007/008/009/010/013/015, including what evidence each platform can automate and where you'll still need separate tooling.
If your primary requirement is NERC-CIP compliance plus continuous OT/ICS security monitoring for a utility, I’d put Claroty, Nozomi Networks, and Dragos at the center of the evaluation. There isn't a universally “best” product because the right choice depends heavily on your generation/transmission/distribution architecture, existing SIEM/SOC stack, and how much of the compliance evidence you want automated.
Utilities already heavily invested in Microsoft/Sentinel
OT network sensors, asset/vulnerability visibility, anomalous-behavior monitoring, and hybrid/air-gapped deployments.
My practical recommendation
For a utility starting a NERC-CIP-focused OT security program today, I would run a bake-off between Claroty and Nozomi, with Dragos included if advanced OT threat detection/threat intelligence is a major requirement.
The distinction I'd investigate is:
Claroty — particularly compelling if you want a broader CPS platform that combines OT visibility, vulnerability/configuration management, compliance support, and secure third-party access. Its published NERC mapping is unusually comprehensive.
Nozomi — particularly compelling if your priority is continuous passive monitoring, anomaly detection and automated compliance evidence, especially as you prepare for CIP-015-1.
Dragos — particularly compelling where ICS-specific threat detection, threat intelligence and incident response are the dominant requirements. Its platform is explicitly designed around OT environments rather than being an IT security product extended into OT.
Microsoft Defender for IoT — worth serious consideration if you already have a substantial Microsoft security/Sentinel footprint and want to integrate OT telemetry into that ecosystem.
One important NERC-CIP consideration
I would not evaluate these merely as “OT vulnerability scanners.” NERC's requirements span much more than vulnerabilities. For example, CIP-010 addresses configuration-change management and vulnerability assessments, while the current CIP standards also include electronic security perimeters, system security management, incident response, recovery, supply-chain risk, and the newer CIP-015-1 Internal Network Security Monitoring requirement.
CIP-015-1 is especially important for a new purchase. It requires monitoring inside relevant ESPs rather than relying solely on perimeter controls, including collection of network data, anomaly detection/evaluation, and retention/protection of monitoring information.
CIP-005 — ESP visibility and communications monitoring.
CIP-007 — security-event monitoring and system-security controls.
CIP-008/009 — incident investigation and recovery evidence.
CIP-013 — vulnerability/supply-chain visibility.
Audit evidence — ability to produce defensible evidence rather than simply saying "compliant."
Air-gapped / low-connectivity architecture — critical for many utility environments.
SIEM/SOC integration — particularly Splunk, Microsoft Sentinel, QRadar, etc.
OT-safe operation — passive monitoring should be the default; avoid IT-style aggressive scanning on sensitive control networks.
Multi-site scalability — generation, substations, control centers, transmission/distribution, and corporate environments.
One caveat: no product by itself makes a utility NERC-CIP compliant. The standards impose organizational processes, policies, personnel, physical security, documentation, response/recovery procedures and other controls that a monitoring platform can support but cannot replace. NERC's own standards page identifies the individual CIP requirements and their enforcement status.
If you tell me (1) generation vs. transmission/distribution, (2) approximate number of substations/sites, (3) whether you already use Microsoft Sentinel/Splunk, and (4) whether you need on-prem/air-gapped deployment, I can turn this into a utility-specific Claroty vs. Nozomi vs. Dragos comparison, including the NERC-CIP controls each product addresses and the questions I'd put in the RFP.
When dealing with NERC-CIP compliance in an OT/ICS utility environment, there is no single "silver bullet" tool that does everything out-of-the-box without operational friction. Instead, the market leaders split into two distinct philosophies: deep configuration/compliance automation and deep threat detection/network monitoring (especially with the enforcement of standards like NERC CIP-015 for Internal Network Security Monitoring - INSM).
Most mature utilities actually deploy a combination of these platforms. The top solutions on the market categorized by their strengths for NERC-CIP compliance include:
1. The Compliance & Configuration Heavyweight
Industrial Defender : If your absolute biggest pain point is audit fatigue, artifact collection, and proving configuration baselines to NERC auditors, Industrial Defender is traditionally considered the gold standard.
Why it fits: Unlike pure network monitors, it uses lightweight agents and deep endpoint integration to track configuration management, security baselines, patch tracking, and automated audit reporting. It turns a grueling manual spreadsheet audit into a click-of-a-button process.
2. The Threat Detection & Threat Intelligence Leaders
Dragos Platform : Highly specialized for industrial control systems, Dragos is built by ICS/OT practitioners with an unmatched threat intelligence arm (Dragos Worldview and OT Watch managed services).
Why it fits: They provide robust tools tailored for NERC CIP requirements—offering perimeter and internal visibility (ESP ingress/egress), centralized audit logging, backup/restore tracking, and vulnerability prioritization specifically calibrated for OT constraints.
Nozomi Networks : Known for massive scalability and exceptional asset discovery across distributed utility grids, substations, and generation plants.
Why it fits: Nozomi provides dedicated NERC CIP mapping templates, robust anomaly detection, and powerful INSM capabilities to satisfy modern internal monitoring expectations cleanly across multi-site utility footprints.
Which one should you pick?
Choose Industrial Defender if your compliance team is drowning in paperwork, change-tracking logs, and configuration baselines for CIP-002 through CIP-011.
Choose Dragos or Nozomi Networks if your primary directive is deep network packet inspection, anomaly detection, and satisfying the heavy technical monitoring expectations of NERC CIP-015 (Internal Network Security Monitoring).
To help narrow down which platform fits your architecture best, tell me:
Are you leaning more toward easing auditor artifact collection or deep packet threat detection (INSM/CIP-015)?
Are you primarily a generation, transmission, or distribution utility?
Yes. If NERC-CIP compliance is the primary requirement, I would put Nozomi Networks, Claroty, and Dragos at the top of the shortlist—but my current pick for a utility specifically wanting OT/ICS security + continuous NERC-CIP compliance monitoring/evidence is Nozomi Networks.
Nozomi has unusually direct alignment with what you're asking for. Its platform is designed around OT/ICS asset discovery, continuous monitoring, anomaly/threat detection, vulnerability management and compliance evidence, rather than treating OT as an extension of an IT security product.
Most importantly for your use case, Nozomi explicitly maps its platform to the active NERC-CIP requirements and provides audit-ready evidence and NERC-CIP-specific queries. It says its platform supports the active standards except the two physical-security-focused standards.
The other major reason I'd put it first today is CIP-015-1. NERC's internal network security monitoring requirement is a major change for utilities: high- and medium-impact BES Cyber Systems with external routable connectivity have an October 1, 2028 compliance date, while other BES Cyber Systems with that connectivity have an October 1, 2030 date. Nozomi has built specific INSM functionality around anomaly detection, investigation records, data retention and integrity.
That makes Nozomi particularly interesting if you're buying a platform now rather than simply trying to satisfy today's audit.
Its platform covers asset discovery, network monitoring, vulnerability/exposure management, remote access and compliance. Claroty specifically documents support across NERC-CIP requirements including CIP-007, CIP-010, CIP-012 and CIP-013.
Claroty is particularly compelling if you have a large heterogeneous CPS environment extending beyond traditional SCADA—IoT, building systems, medical/other connected devices, remote access, etc. Its current electric-utility offering also emphasizes automated regulatory reporting and proof packs.
Dragos would be my first choice if the question were:
"Which platform gives our SOC the strongest specialized capability for detecting and responding to sophisticated attacks against electric-sector OT?"
Dragos has particularly deep expertise in industrial threat intelligence, adversary behavior, threat hunting and incident response. Its electric-grid offering is explicitly tailored to generation, transmission and distribution environments, and its NERC-CIP approach covers asset visibility, vulnerability management, threat detection and response.
The tradeoff is that I'd view Dragos somewhat more as a best-in-class OT security/threat-detection platform with strong NERC-CIP support, whereas Nozomi and Claroty make the continuous compliance/evidence workflow more central to the platform.
The important distinction: "NERC-CIP compliant" ≠ "buying a compliant product"
This is the part I'd emphasize to management.
No product by itself makes a utility NERC-CIP compliant. The platform provides technical controls, monitoring, records and evidence that support your compliance program. Your policies, procedures, categorization, documentation, personnel controls, incident processes, training, physical security, supply-chain processes, etc. still matter.
So I wouldn't evaluate vendors based on a checkbox saying "supports CIP-002 through CIP-015."
I'd run a proof-of-concept against your actual audit workflow.
I'd make vendors demonstrate these seven things
Complete BES Cyber Asset/BES Cyber System inventory
passive discovery
device identity/model/firmware
communication relationships
high/medium/low impact categorization support
CIP-005 Electronic Security Perimeter
ESP visibility
EACMS visibility
communications mapping
unauthorized connection detection
CIP-007 System Security Management
ports/services
configuration changes
malware/IOC detection
baseline deviation
CIP-010 Configuration & Vulnerability Management
baseline creation
change detection
vulnerability identification
compensating-control documentation
That last point is critical. OT security isn't simply "deploy an EDR everywhere." Legacy and safety-critical devices often can't tolerate conventional agents or aggressive scanning.
And I'd make CIP-015-1 a mandatory part of the evaluation rather than treating it as a future checkbox. The requirement is already approved, and the implementation deadlines make it something you want your architecture to accommodate now.
If you tell me the size/type of utility (generation, transmission, distribution, municipal/public power), approximate number of substations/sites, and whether you need on-prem, SaaS, or hybrid, I can build you a Nozomi vs. Claroty vs. Dragos comparison matrix mapped requirement-by-requirement to CIP-002 through CIP-015, including what I'd put into the RFP/POC test plan.
When tackling NERC-CIP compliance in an OT/ICS environment, utilities face a unique challenge: compliance isn't a one-time annual event, and the standards (such as the mandates under CIP-002 through CIP-014, plus newer internal network monitoring requirements like CIP-015) are intensely prescriptive.
The "best" solution usually involves a two-layered approach , because no single tool magically solves deep asset discovery, continuous network threat detection, and the tedious evidence-management/audit-trail reporting required for NERC auditors.
Top-tier platforms dominate the utility sector for OT/ICS cybersecurity and compliance monitoring, categorized by their primary strengths:
1. The Pure Compliance & Configuration Management Leader
Industrial Defender: If your primary nightmare is audit day, tracking baseline configurations, and managing change control evidence (CIP-010, CIP-007), Industrial Defender is purpose-built for this. Unlike generic IT tools, it focuses heavily on deep host-level configuration management, software inventories, account management, and automated compliance reporting tailored specifically to NERC CIP standards. Many large utilities use it as their single source of truth for audit binders and Reliability Standard Audit Worksheets (RSAWs).
2. The Big Three OT Visibility & Threat Detection Platforms
If you need deep passive/active packet inspection, anomaly detection, and asset discovery to map your Bulk Electric System (BES) cyber assets, the industry consensus points to these three powerhouse platforms. They all map heavily to NERC CIP controls and integrate with SIEMs:
Nozomi Networks: Noted for superior scalability and exceptional asset discovery in massive transmission and generation environments. Its Guardian platform provides real-time ICS network visibility, deeply supporting NERC CIP baseline security requirements and automated monitoring.
Claroty: Offers an exceptionally robust suite (Claroty xDome/Continuous Threat Detection) covering everything from vulnerability management to secure remote access (vital for CIP-005/CIP-013 supply chain compliance). They excel at bridging IT/OT convergence security.
Dragos: Renowned for world-class threat intelligence tailored explicitly to industrial control systems and electric sector threat groups. If your board cares deeply about active adversary mitigation and industrial incident response readiness (CIP-008), Platform is a top contender.
3. The Enterprise Ecosystem Approach
Microsoft Defender for IoT / Tenable OT Security / Fortinet: Many utilities already heavily invested in Microsoft enterprise ecosystems or ruggedized perimeter firewalls (Fortinet OT Security ) use these natively integrated tools. While great for general visibility and vulnerability prioritization, they often require companion specialized governance tools to handle full NERC CIP audit evidence workflows.
The Reality: How Utilities Actually Deploy
Because passive network monitoring (Nozomi, Claroty, Dragos) and endpoint/configuration compliance tracking (Industrial Defender) solve different parts of the standard, many enterprise utilities deploy a hybrid architecture . They use a tool like Nozomi or Dragos for real-time threat detection and network segmentation monitoring (satisfying emerging mandates like CIP-015), paired with Industrial Defender for deep configuration baselining and automated audit evidence generation.
To help narrow down the ideal architecture for your utility, tell me:
Are you primarily focused on transmission, generation, or distribution?
Is your biggest pain point daily threat detection or audit evidence collection/RSAWs?
Do you have an existing SIEM/SOAR stack (like Splunk or Microsoft Sentinel) you need to feed into?
If NERC-CIP compliance + continuous OT/ICS monitoring is the core requirement, I would shortlist Nozomi Networks, Claroty, and Dragos. There isn't a product that makes a utility “NERC-CIP compliant” by itself—the platform has to generate evidence and support the utility's documented controls, procedures, and audit process. NERC currently lists CIP-002 through CIP-015, with several newer revisions already designated for future enforcement.

This aligns with recent industry comparisons that put Claroty, Nozomi, and Dragos among the leading OT-native platforms.
1. 🥇 Nozomi Networks — my first choice for compliance monitoring
I'd start with Nozomi if the question is:
“How do we continuously monitor our OT environment and make NERC-CIP audits substantially easier?”
Nozomi specifically provides automated asset inventory, behavioral baselining, vulnerability mapping, threat/anomaly detection, risk scoring, forensic capture, and audit-ready NERC-CIP evidence, including prebuilt dashboards and NERC-CIP queries.
That makes it particularly attractive for a geographically distributed utility with lots of substations and BES Cyber Systems.
3. 🥉 Dragos — best if detecting an attacker is the priority
If your security team is more concerned with:
“Can we detect and investigate an adversary moving through our substations?”
I'd put Dragos at the top.
Dragos is particularly strong in ICS-specific threat detection, deep protocol analysis, OT threat intelligence, vulnerability management, investigation, and threat hunting. Its platform also explicitly supports NERC-CIP workflows, including CIP-010 and CIP-015.
For a serious utility, I wouldn't evaluate these merely as “SIEM alternatives.” I'd build the architecture roughly like:
OT sensors → OT asset inventory → continuous network monitoring → vulnerability/configuration monitoring → NERC-CIP evidence → SIEM/SOC
The important part is that the platform needs to help you demonstrate the controls, not merely identify vulnerabilities.
For example, CIP-010 specifically requires configuration-change management and vulnerability-assessment activities intended to prevent and detect unauthorized changes to BES Cyber Systems. NERC Likewise, the newer CIP-015 requirements make internal network security monitoring increasingly important.
The evaluation I'd use in an RFP
Don't ask vendors simply, “Do you support NERC-CIP?” Ask them to demonstrate these things against your actual environment:
CIP-002: automated BES Cyber Asset/System inventory and categorization support
CIP-005: ESP visibility, communications, remote access and access monitoring
CIP-010: configuration baselines, unauthorized-change detection and vulnerability assessments
CIP-011: information protection
CIP-012: control-center communications visibility
CIP-013: supply-chain/vendor-risk workflows
CIP-015: internal network security monitoring
Audit evidence: immutable/retained evidence, timestamps, exportable reports, chain of custody
OT safety: passive-first monitoring and no disruptive scanning
SIEM integration: Splunk, Sentinel, QRadar, etc.
Multi-site architecture: central management across substations/generation facilities
Air-gapped/segmented environments
RBAC/MFA and separation of duties
One particularly important test: give each vendor a representative substation and ask them to produce the actual audit evidence for a selected CIP requirement, rather than showing you a marketing dashboard.
Bottom line
If I had to pick one platform based solely on your stated problem, I'd start with Nozomi Networks because the combination of OT visibility, continuous monitoring, and explicit NERC-CIP evidence generation is unusually well aligned with the requirement.
I'd run a serious bake-off against Claroty and Dragos, though:
If you tell me whether you're generation, transmission, distribution, or a vertically integrated utility, plus roughly how many substations/sites you have and whether you're using Splunk, Microsoft Sentinel, or another SIEM, I can give you a much more concrete Nozomi vs. Claroty vs. Dragos architecture and 2026 RFP scorecard.
Complying with NERC-CIP (specifically with newer mandates like CIP-015 for Internal Network Security Monitoring and tightened Low/Medium/High impact controls) means manual audits and retrofitted IT tools won't cut it.
The "best" solution depends on whether your priority leans heavily toward pure configuration/compliance automation or deep industrial threat detection and passive network monitoring.
The top-tier OT/ICS platforms heavily relied upon by North American utilities break down as follows:
1. Industrial Defender (Best for Deep Configuration & Audit Automation)
If your primary pain point is the sheer administrative burden of proving compliance, generating evidence, and tracking configuration baselines across assets, Industrial Defender is widely considered the gold standard.
Why it shines for NERC-CIP: It was built from the ground up for compliance and change management in operational technology. It excels at automating RSAW (Reliability Standard Audit Worksheet) data collection, tracking baseline configurations, and handling patch/vulnerability management across Low, Medium, and High impact BES Cyber Systems.
Key advantage: It bridges the gap between the compliance team and the OT security team by turning continuous monitoring into audit-ready evidence automatically rather than forcing manual spot-checks.
2. Dragos Platform (Best for Threat Intelligence & Network Visibility)
If your focus is stopping sophisticated adversaries, complying with internal network monitoring mandates, and leveraging top-tier industrial threat feeds, Dragos leads the pack.
Why it shines for NERC-CIP: Dragos provides exceptional passive network monitoring that directly addresses requirements like NERC CIP-015 (Internal Network Security Monitoring) by tracking lateral movement and anomalous east-west traffic inside your control zones. They also offer specialized NERC CIP addendums and guidance packs (like for CIP-013 supply chain risks).
Key advantage: Unmatched OT-native threat intelligence (WorldView/Knowledge Packs) designed specifically to spot attacker behaviors targeting electric and critical infrastructure sectors.
3. Claroty (Best for Comprehensive Cyber-Physical Asset Discovery)
Claroty offers a heavily adopted, highly versatile Cyber-Physical Systems (CPS) protection platform tailored to the convergence of utility IT and legacy OT networks.
Why it shines for NERC-CIP: Claroty covers continuous asset discovery, vulnerability management, and secure remote access—vital for satisfying the rigorous access control rules mandated across utility substations and control centers.
Key advantage: Flexible deployment (on-premises, cloud, or hybrid) with deep protocol parsing for SCADA and ICS environments, making it seamless to gain visibility into unmanaged or legacy sub-station assets.
Which one should you pick?
Choose Industrial Defender if your greatest dread is the audit cycle and you need bulletproof configuration management, change tracking, and automated compliance artifact generation.
Choose Dragos if you are prioritizing advanced threat defense , robust incident response readiness, and compliance mapping for network traffic rules like CIP-015.
To help narrow down which platform fits your environment best, tell me:
What is your current mix of impact levels (mostly Low-impact sites, or a heavy footprint of Medium/High-impact control centers)?
Are you leaning more toward solving an upcoming audit/documentation bottleneck or upgrading active threat detection/SOC monitoring?
The best OT/ICS cybersecurity solutions for NERC CIP compliance are Nozomi Networks, Dragos, Claroty , and Industrial Defender . Because NERC CIP mandates strict, technical controls across different operational layers, utilities generally deploy a combination of specialized OT monitoring platforms and configuration management tools rather than a single, all-in-one product.
The regulatory landscape requires distinct capabilities to address specific mandates like the newer CIP-015-1 Internal Network Security Monitoring (INSM) rules and long-standing configuration baselining requirements (CIP-010).
The top-rated technical solutions on the market excel across these regulatory categories:
These platforms use passive monitoring to safely identify anomalies inside the Electronic Security Perimeter (ESP) without disrupting sensitive utility operations.
Nozomi Networks Guardian:
Best For : Native alignment with the new CIP-015-1 INSM mandates for deep lateral traffic visibility within trusted networks.
Key Features : Auto-generates exact network topologies and automates real-time threat detection across substations.
Dragos Platform:
Best For : Advanced, utility-specific threat intelligence and incident response frameworks (CIP-008).
Key Features : Leverages highly specialized playbook rules designed specifically for electric grid defense and SCADA protocols.
Passive Network Analysis : Active scanning can crash older substation relays. Choose solutions that parse network SPAN/TAP ports.
Automated Baselining : Manual port and service checks fail audits. Your solution must automatically alert you if an unauthorized port opens (CIP-007-6 R3).
Supply Chain Validation : Platforms must evaluate and log vendor remote access behaviors to comply with CIP-013 and updated CIP-003-9 rules.
If you want to tailor this further, please tell me:
What impact rating are your assets (High, Medium, or Low impact)?
Are you looking for a solution that covers endpoint configuration data or network monitoring?
Do you have an existing IT SIEM or SOC that this OT system needs to integrate with?
If you’re a North American electric utility subject to NERC-CIP, I’d shortlist Dragos, Claroty, and Nozomi Networks. There isn’t a single product that makes an entity “NERC-CIP compliant”—the standards cover governance, personnel, physical security, access controls, incident response, recovery, supply chain, etc. The platform should instead automate evidence collection, monitoring, and controls around the parts it can actually address. NERC’s current standards list confirms, for example, CIP-002, -003, -004, -005, -006, -007, -008, -009 and -010 as mandatory/subject to enforcement, with newer versions moving through future enforcement.
My recommendation
1. Dragos — best overall for high-consequence electric utilities
I would put Dragos at the top if your primary objective is OT threat detection + incident response + NERC-CIP support.
Dragos is particularly strong in electric-sector OT and has a purpose-built platform covering asset visibility, threat detection, vulnerability management, investigation/response, and OT threat intelligence. Its NERC-CIP implementation specifically addresses workflows around CIP-002 through CIP-015, including CIP-005, CIP-007, CIP-008, CIP-010 and CIP-015.
Good support for CIP-010 vulnerability/configuration activities
Strong fit for CIP-015 Internal Network Security Monitoring
Optional managed OT monitoring/threat hunting through OT Watch
Deep expertise in utility-specific adversary activity
Best fit: Transmission operators, large generation companies, large IOUs, and utilities where security operations and threat detection are more important than simply producing compliance reports.
2. Nozomi Networks — best for compliance-centric OT visibility
Nozomi Networks would probably be my choice if your biggest pain is:
“We need continuous OT visibility and automated evidence that we can use during NERC audits.”
Nozomi explicitly positions its platform around automated NERC-CIP compliance and says it supports the active NERC-CIP standards except the two physical-security-focused standards. It provides automated asset inventory, behavioral baselining, vulnerability mapping, threat detection, risk scoring, forensic capture and audit-ready compliance evidence.
It also has a particularly strong utility focus across generation, transmission and distribution, including geographically distributed substations.
Best fit: Utilities where asset inventory + continuous monitoring + compliance evidence/audit preparation are the dominant requirements.
3. Claroty — best for broad CPS/OT visibility and modern hybrid environments
Claroty is another top-tier choice, especially if your environment extends beyond traditional SCADA into IoT, building systems, medical/enterprise CPS, remote access and modernized grid infrastructure.
Claroty offers both cloud-based xDome and on-premises CTD, along with secure remote access. Its utility offering emphasizes asset discovery, exposure management, threat detection and automated NERC-CIP compliance evidence.
Its current electric-utility materials specifically describe automated mapping of OT/IoT assets to NERC CIP and generation of audit-ready compliance packages.
Best fit: Utilities undergoing grid modernization, with lots of heterogeneous CPS/OT assets and a desire to consolidate visibility and remote access.

NERC-CIP evidence/compliance
The important distinction
I wouldn't select based on a vendor's claim that it “supports NERC-CIP.”
I'd build the evaluation around your actual CIP obligations.
For example:
CIP-002: Can it discover and maintain an authoritative inventory of BES Cyber Systems and associated assets?
CIP-005: Can it continuously identify communications crossing Electronic Security Perimeters and unauthorized access paths?
CIP-007: Can it detect suspicious services, authentication behavior, malicious activity and unauthorized changes?
CIP-008: Does it provide useful detection, investigation, evidence retention and incident workflow?
CIP-009: Can it contribute evidence to recovery processes?
CIP-010: Can it establish configuration baselines and identify unauthorized changes?
CIP-011: Does it protect and appropriately handle sensitive cyber information?
CIP-013: Does it integrate with your supply-chain/vendor risk process?
CIP-015: Can it provide continuous internal network security monitoring, including east-west traffic inside applicable trusted zones?
CIP-015 is especially important in a modern evaluation. Dragos, Nozomi and Claroty all address it, but their approaches and operational workflows differ.
What I'd actually buy
For a large electric utility, my preferred architecture would be:
Dragos + existing SIEM/SOC + dedicated NERC-CIP GRC/evidence process
rather than trying to make one OT platform do everything.
If compliance automation is the #1 priority, I'd seriously consider:
Nozomi Networks + SIEM + GRC
If you have a highly heterogeneous environment and want OT security + exposure management + secure third-party access, I'd put:
Claroty xDome/CTD
very high on the list.
Bottom line
My overall pick: Dragos if you're asking, “What is the strongest cybersecurity platform for protecting a serious electric utility OT environment?”
My pick for compliance-centric operations: Nozomi Networks.
My pick for broad modern CPS/OT management and secure access: Claroty.
And I would not purchase any of the three solely on a NERC-CIP feature matrix. The deciding factor should be a proof-of-value using your actual substations/control centers, ESP architecture, protocols, BES Cyber Systems and CIP-015 monitoring requirements.
If you tell me whether you're generation, transmission, distribution, municipal/co-op, or an IOU, and roughly how many substations/sites you have, I can give you a much more specific Dragos vs. Nozomi vs. Claroty architecture and TCO comparison, including which one I'd select for your environment.
