Which Zero Trust Network Access (ZTNA) solution is the best replacement for a traditional corporate VPN?

Short answer

If you mean “What should a typical enterprise buy to replace its traditional remote-access VPN?”, my default recommendation in 2026 is Zscaler Private Access (ZPA).

It is particularly strong for large organizations because it replaces “put the user on the corporate network” with identity- and policy-based access to specific private applications, reducing lateral-movement exposure. Independent 2026 comparisons continue to put ZPA among the leading enterprise ZTNA platforms.

CISA and its partners explicitly recommend moving away from broad traditional VPN access toward more granular, identity/context-aware approaches such as ZTNA, SSE, and SASE.

My shortlist

Current comparisons similarly distinguish Zscaler/Palo Alto as enterprise-scale SASE choices, while Cloudflare, Twingate and Tailscale tend to be easier/faster VPN-replacement deployments.

What I'd choose by organization

• 5,000+ users / global enterprise: Zscaler ZPA
• 500–5,000 users: Zscaler ZPA, Cloudflare One, or Prisma Access, depending on your existing security stack.
• 50–500 users: Cloudflare Access or Twingate
• Engineering-heavy organization: Tailscale or Twingate
• Already standardized on Palo Alto: Prisma Access
• Already standardized on Microsoft Entra: Entra Private Access
• Strong DLP/compliance requirements: Netskope

The most important caveat is that ZTNA isn't simply “a better VPN.” A good implementation grants access to applications/resources, not an entire subnet. If you configure the product to effectively give users broad network access, you've recreated much of the VPN's security problem under a different name.

If you tell me your approximate user count, whether apps are on-prem/AWS/Azure/SaaS, your IdP (Entra/Okta/etc.), and whether you already use Palo Alto/Zscaler/Cloudflare, I can narrow this to the best 2–3 choices and compare licensing, architecture, performance, and migration effort.

Current comparisons similarly distinguish Zscaler/Palo Alto as enterprise-scale SASE choices, while Cloudflare, Twingate and Tailscale tend to be easier/faster VPN-replacement deployments.

What I'd choose by organization

There is no single "best" ZTNA solution for every organization, because the right choice depends heavily on your current infrastructure, cloud footprint, and budget. However, industry leaders categorized under the Secure Access Service Edge (SASE) and Security Service Edge (SSE) frameworks consistently rank at the top for replacing traditional corporate VPNs.

Leading ZTNA solutions are categorized below by their primary strengths:

• Zscaler (Zero Trust Exchange): Best for a pure cloud-native approach. It routes user connections directly to applications via a massive global cloud architecture rather than placing users on a network layer, completely eliminating lateral movement.
• Palo Alto Networks (Prisma Access): Best for enterprise-grade hybrid environments. It combines robust firewall-level security inspection with high-performance global scaling, making it ideal for organizations heavily invested in Palo Alto's hardware or cloud ecosystem.
• Cloudflare One: Best for speed, ease of use, and edge-native performance. Cloudflare’s ZTNA integrates smoothly with its massive global edge network, offering exceptional user experience and fast, simplified policy management.
• Microsoft Entra Private Access: Best for organizations deeply embedded in the Microsoft 365 / Entra ID (Azure AD) ecosystem. It natively ties conditional access policies directly to user identities and device postures already managed in Entra.
• Netskope (One SSE): Best for data-centric security. It heavily emphasizes inline data loss prevention (DLP) and deep inspection, ensuring that data moving to private apps via ZTNA is tightly monitored.

How to Choose the Right One for You

Instead of looking for a universal winner, evaluate solutions based on these core criteria:

1. App Location: Are your applications hosted locally in an on-premises data center, spread across AWS/Azure, or a mix of both? (Ensure the ZTNA vendor has a lightweight connector that supports your private network layout).
2. Ecosystem Integration: Does it plug smoothly into your existing Identity Provider (IdP) like Okta, Microsoft Entra ID, or Google Workspace?
3. User Experience (UX): Does it require a heavy client agent on employee laptops, or does it run seamlessly in the background without causing latency?

To help narrow down the best fit, tell me:

• Where are your primary applications hosted (AWS, Azure, on-prem data centers, or a mix)?
• What identity provider do you currently use (Microsoft Entra ID, Okta, etc.)?
• Roughly how many remote users need coverage?

There is no single "best" Zero Trust Network Access (ZTNA) solution for everyone, because the right choice depends heavily on your existing tech stack, company size , and infrastructure complexity . Instead of a one-size-fits-all product, the market is led by top contenders categorized by use case.

Top Enterprise & Cloud-Scale Leaders

• Zscaler Private Access (ZPA): Widely considered the gold standard for large global enterprises. It isolates private apps seamlessly without putting users on the network, but it works best if you lean fully into the broader Zscaler Zscaler Zero Trust Exchange ecosystem.
• Netskope Private Access: A consistent Gartner Leader in Security Service Edge (SSE). Excellent for data-centric security and organizations looking for deep inline data loss prevention (DLP) alongside ZTNA.
• Palo Alto Prisma Access: Best for organizations already invested in Palo Alto hardware/infrastructure who want heavy-duty traffic threat inspection paired directly with remote access.

Best for Agility, Speed, and Simplicity

• Cloudflare Access (Cloudflare One): Outstanding for fast, frictionless rollouts (including clientless/browser-based options) leveraging Cloudflare's massive global edge network. Highly approachable with a strong free tier to start testing.
• Twingate: Highly praised by mid-market and modern engineering teams for being exceptionally fast to deploy and offering precise, resource-level access control without heavy network reconfiguration.
• Tailscale: Built on WireGuard, this is a developer favorite for creating an easy, peer-to-peer zero-trust mesh network without managing complex enterprise appliances.

Best for Ecosystem Consolidation

• Microsoft Entra ID / Intune: If your organization is already deeply embedded in the Microsoft 365/Azure ecosystem, turning on Microsoft’s native conditional access and Global Secure Access ZTNA features provides the path of least resistance.
• Cisco Secure Access / Duo: Ideal if you already rely on Cisco networking gear or Duo Security for robust, phishing-resistant multi-factor authentication (MFA) and device posture checks.

To help narrow down which solution fits your environment, tell me:

• What is your primary identity provider (e.g., Microsoft Entra ID, Okta, Google Workspace)?
• Are your internal apps hosted mostly in the cloud (AWS/Azure/GCP) or on-premises/data centers?
• Roughly how many remote users need access?

If you mean “What should a company deploy instead of its traditional remote-access VPN?”, my top choice for most organizations in 2026 is Cloudflare One / Cloudflare Access.

The important caveat is that there isn't one universal winner: Zscaler Private Access can be the better choice for a large enterprise already invested in SSE/SASE, while Microsoft Entra Private Access is especially compelling in Microsoft-heavy environments.

My shortlist

Why I'd pick Cloudflare

Cloudflare's architecture is particularly well suited to replacing the “connect to the corporate network” VPN model. Instead of putting a user onto a subnet, it authenticates the user and device and grants access to specific private applications/resources. Cloudflare supports device-to-network, device-to-device, and network-to-network scenarios.

It also gives you a relatively gradual migration path: you can move your highest-risk applications/users first and eventually eliminate the VPN rather than doing a big-bang migration.

Cloudflare Access supports both browser-based/clientless access and client-based access for things such as SSH, RDP and other TCP/UDP resources, which makes it considerably more capable than simply putting an identity proxy in front of web applications.

When I would choose something else

• Choose Zscaler ZPA if you're a large enterprise already standardizing on Zscaler's SSE/SASE ecosystem. It's one of the strongest choices for a comprehensive enterprise ZTNA program.
• Choose Entra Private Access if your organization is deeply invested in Microsoft Entra ID, Intune and Microsoft's security stack. The integration can outweigh differences between ZTNA products.
• Choose Netskope if ZTNA needs to be part of a broader Netskope security/SSE deployment; its current offering explicitly targets VPN replacement as well as legacy application access.
• Choose Twingate if you primarily want to replace a conventional VPN quickly without taking on a huge SASE platform. Independent 2026 comparisons specifically identify it as a strong option for small and midsize organizations seeking straightforward VPN replacement.
• Choose Tailscale if the problem is predominantly developer/server/infrastructure connectivity rather than conventional employee-to-business-app access.

Bottom line: For a greenfield corporate VPN replacement, I'd start with Cloudflare One and Zscaler ZPA as the two products to evaluate seriously, then add Entra Private Access if you're a Microsoft-centric organization.

If you tell me your company size, whether you're Microsoft/Google-centric, on-prem vs. cloud, and what the VPN currently provides (RDP/SSH/file shares/full network access/etc.), I can give you a much more specific recommendation and a Cloudflare vs. Zscaler vs. Entra comparison.

When I would choose something else

There is no single "best" ZTNA solution for everyone, because the right choice depends heavily on your existing cloud footprint, infrastructure, and security stack. However, industry leaders consistently break down into top contenders depending on what your organization prioritizes.

Leading ZTNA platforms serving as robust VPN replacements include:

• Zscaler Private Access (ZPA): Best for massive global enterprises needing scale. It uses a true cloud-native architecture via the Zscaler Zero Trust Exchange , connecting users directly to specific applications rather than placing them on the network, which completely eliminates lateral movement.
• Cloudflare One (Cloudflare Access): Best for speed, simplicity, and ease of deployment. It integrates smoothly with identity providers and leverages Cloudflare's massive global edge network, making it a favorite for modern development teams and agile enterprises looking to augment or replace a VPN quickly.
• Palo Alto Networks (Prisma Access): Best for organizations deeply invested in a comprehensive Secure Access Service Edge (SASE) framework and hardware-to-cloud unification. It excels if you need deep, rigorous traffic inspection alongside strict zero-trust controls.
• Microsoft Entra Private Access: Best for organizations heavily entrenched in the Microsoft 365 and Entra ID (formerly Azure AD) ecosystem. It natively extends conditional access policies to on-premises applications without requiring complex third-party integrations.
• Cisco Secure Access: Best for enterprises already utilizing Cisco infrastructure (such as AnyConnect/Secure Client migrations), offering unified security across web, cloud, and private applications.

To help narrow down which solution fits your environment best, tell me:

• What identity provider (IdP) do you use (e.g., Microsoft Entra ID, Okta, Ping)?
• Are your corporate applications hosted on-premises, in the cloud (AWS/Azure/GCP), or a hybrid of both?
• Do you prefer a pure cloud-native service or a vendor that integrates with your existing hardware firewalls?

If your goal is replacing a traditional corporate remote-access VPN, my default recommendation is Zscaler Private Access (ZPA).

My ranking

🥇 Best overall: Zscaler Private Access

ZPA is particularly strong when you're trying to retire VPN infrastructure rather than simply replace it with another network tunnel.

Traditional VPN:

User → VPN → Corporate network → Application ZTNA:

User → Identity/device verification → Specific application ZPA brokers one-to-one connections between authorized users and applications, meaning the user doesn't receive general network access. Zscaler also supports application discovery, granular segmentation, third-party/BYOD access, RDP/SSH/VNC, and agentless browser access.

That's the architectural change I'd prioritize: don't recreate your VPN's broad network access model inside a ZTNA product.

🥈 Best value: Cloudflare

Cloudflare is probably my choice if you're a smaller organization or already heavily invested in Cloudflare.

Cloudflare Access can protect internal web applications without a VPN, while Cloudflare's private-network functionality supports private IPs, hostnames and ranges through its client/tunnel architecture.

It's especially attractive if your requirements are:

• Web apps and SaaS
• SSH/RDP/private services
• Remote employees and contractors
• Minimal infrastructure
• Strong identity-based policies
• Good price/performance

🥉 Best if you're a Microsoft shop: Entra Private Access

If you already have Microsoft Entra ID + Intune + Microsoft 365, I'd seriously consider Microsoft Entra Private Access before buying a separate ZTNA platform.

Microsoft explicitly positions it as a VPN replacement, including a "Quick Access" mode that can initially provide VPN-like connectivity and then allow you to progressively move toward per-application segmentation.

That migration path is important: you can get off the VPN first and tighten access afterward.

The decision I'd make

Choose ZPA if:

• 500+ employees
• Hybrid/multicloud environment
• Lots of legacy/on-prem applications
• Security is a major priority
• You want mature enterprise ZTNA/SSE capabilities
• You expect to eliminate VPN entirely

Choose Cloudflare if:

• You're smaller or cloud-native
• Cost and simplicity matter
• You have lots of web applications
• You already use Cloudflare

Choose Entra Private Access if:

• You're heavily standardized on Microsoft
• Entra ID/Intune are already deployed
• You want the fewest additional vendors

Choose Twingate/Tailscale if:

• You're primarily trying to solve straightforward private infrastructure access
• You don't need a large enterprise SSE/security platform

One caveat: ZTNA isn't automatically a 1:1 VPN replacement. If your VPN currently provides access to arbitrary network protocols, legacy applications, VoIP, network shares, industrial systems, etc., you need to inventory those flows first. The strongest ZTNA architecture is to progressively turn network access into application/service access, rather than recreating the old VPN subnet wholesale.

Bottom line: For a typical enterprise starting a serious VPN-replacement project in 2026, I'd shortlist Zscaler ZPA, Cloudflare, and Microsoft Entra Private Access, with ZPA as my overall default pick.

It's especially attractive if your requirements are:

There is no single “best” ZTNA replacement for a corporate VPN; the right choice depends on your existing security stack, application mix, scale, and whether you want a standalone VPN replacement or a broader Security Service Edge (SSE)/SASE platform. Leading options today include Zscaler Zscaler Private Access, Palo Alto Networks Prisma Access, Netskope Private Access, Cloudflare Access, and Microsoft Entra Private Access.

Short answer

For most large enterprises replacing a traditional VPN:

1. Best overall enterprise VPN replacement: Zscaler Private Access (ZPA)

• Strongest fit for organizations moving toward a full zero-trust architecture.
• Mature application-level access model: users connect to specific apps, not the corporate network.
• Good choice for thousands to hundreds of thousands of users and globally distributed workforces.
• Especially attractive if you also want Zscaler Internet Access (ZIA) and a broader SSE strategy.

2. Best if you already run Palo Alto security: Prisma Access

• Natural choice for organizations standardized on Palo Alto firewalls, Panorama, and security tooling.
• Combines ZTNA with cloud-delivered firewalling and broader SASE capabilities.
• Often the lowest-friction migration path for Palo Alto customers.

3. Best for Microsoft-centric organizations: Microsoft Entra Private Access

• Strong fit if your identity platform is already Microsoft Entra ID and Microsoft 365.
• Can reduce the number of separate vendors involved in identity-driven access.
• Particularly attractive for organizations already investing heavily in Microsoft security licensing.

4. Best for data-security-focused organizations: Netskope Private Access

• Good choice when ZTNA is part of a larger data protection strategy involving CASB, DLP, and SaaS security.
• Often selected by organizations where protecting sensitive data is the primary driver.

5. Best lightweight/modern deployment: Cloudflare Access

• Strong fit for web applications, developer teams, and organizations wanting quick deployment.
• Often easier to adopt than large enterprise SSE platforms.
• May require additional design work for complex legacy applications.

Practical decision guide

What I would evaluate before buying

A good VPN replacement should provide:

• Application-level access (not subnet/network access)
• Identity-based policies (user, role, device, risk, location)
• Device posture checks
• Integration with your IdP (Entra ID, Okta, Ping, etc.)
• Support for legacy apps (SSH, RDP, SMB, internal TCP apps)
• Privileged access controls
• Logging/SIEM integration
• A migration path that lets you retire VPN gradually

The biggest architectural mistake is buying “ZTNA” but recreating the old VPN model with broad network access. A true replacement should make internal applications invisible by default and grant only the access required for a specific user and task.

If you share your environment (number of users, cloud/on-prem mix, current VPN vendor, IdP, and whether you use Palo Alto/Cisco/Microsoft security), I can narrow this to a top 2–3 recommendation.

There is no single "best" ZTNA solution for everyone, as the right choice depends heavily on your organization's size, infrastructure, and security maturity. Industry leaders evaluated by Gartner Peer Insights and major security reports generally categorize the top ZTNA alternatives to traditional VPNs into distinct use cases:

• Zscaler Private Access (ZPA): Best for large enterprises wanting a dedicated, cloud-native Security Service Edge (SSE) approach . It excels at app-level segmentation (connecting users directly to specific applications rather than putting them on the network) and scales massively without hardware bottlenecks.
• Cloudflare One (Cloudflare Access): Best for speed, developer-friendly deployment, and small-to-midmarket value. Cloudflare offers a generous free tier for small teams , clientless browser-based access , and an edge network that drastically reduces latency compared to routing traffic through centralized enterprise concentrators.
• Palo Alto Networks Prisma Access: Best for complex hybrid environments. It integrates heavy-duty enterprise firewall controls, advanced threat protection, and robust ZTNA into a unified SASE framework, making it ideal for organizations heavily invested in Palo Alto hardware/ecosystems.
• Tailscale / Twingate: Best for lean IT, engineering teams, and SMBs. Built on WireGuard , Tailscale offers a peer-to-peer mesh overlay that makes setting up secure, zero-trust remote access as simple as logging into an identity provider, entirely bypassing the clunky setup of legacy enterprise agents.
• Microsoft Entra Private Access: Best for Microsoft-centric shops. If your identity backbone is already deeply entrenched in Entra ID (formerly Azure AD) and Microsoft Defender, adding their native ZTNA solution provides frictionless conditional access policy mapping.

To help narrow down which solution fits your environment, tell me:

• Roughly how many remote users do you need to support?
• Are your corporate applications hosted primarily in the cloud (AWS/Azure/GCP/SaaS) or on-premises (data center/legacy servers)?
• What identity provider (IdP) do you currently use (e.g., Microsoft Entra ID, Okta, Google Workspace)?

There is no single "best" ZTNA solution for every organization, because the ideal choice depends heavily on your company's scale, existing infrastructure, and whether you need a pure-play access tool or a comprehensive security service edge (SSE) suite.

The top-tier ZTNA solutions serving as modern corporate VPN replacements fall into distinct categories based on organizational needs:

• Zscaler (Zscaler Private Access - ZPA)
  • Best for: Large enterprise scale and global organizations.
  • Why it works: It pioneered cloud-native ZTNA by connecting users directly to specific applications rather than placing them on the corporate network. It eliminates lateral movement entirely and integrates smoothly if you are already using the Zscaler Zero Trust Exchange for web security.
• Palo Alto Networks (Prisma Access)
  • Best for: Organizations wanting a unified SASE/SSE architecture.
  • Why it works: Offers advanced "ZTNA 2.0" capabilities with continuous trust verification and deep app inspection. It is ideal if you already rely on Palo Alto firewalls or want an integrated ecosystem combining network and endpoint security.
• Cloudflare (Cloudflare One / Access)
  • Best for: Cloud-first teams wanting lightning-fast edge performance.
  • Why it works: Leverages Cloudflare’s massive global edge network. It shines by offering robust Cloudflare Access options—including smooth clientless (browser-based) access for contractors or legacy web apps alongside traditional device-client setups.
• Twingate
  • Best for: Mid-market or growing teams looking for a clean, fast-to-deploy VPN replacement.
  • Why it works: Built specifically to mimic the simplicity of modern software while providing granular, resource-level network segmentation. It is far easier to set up and manage than legacy enterprise heavyweights.
• Tailscale
  • Best for: Engineering-heavy, developer-first, or remote-first teams.
  • Why it works: Built on WireGuard, it creates a peer-to-peer mesh network that is exceptionally fast, lightweight, and easy to configure for connecting developers to internal servers, cloud resources, or remote devices without complex enterprise bloat.

To help narrow down which one fits your environment best, tell me:

• What is your approximate company size?
• Are you primarily looking for clientless access (e.g., for contractors/web apps) or device-managed clients?
• Do you already use a specific cloud ecosystem (AWS/Azure/GCP ) or identity provider (Okta, Microsoft Entra ID) ?

If you want one default recommendation for a traditional corporate VPN replacement, I’d shortlist Zscaler Zscaler Private Access (ZPA).

It is particularly strong for a mid-size or large enterprise because it was purpose-built around the VPN-replacement use case: users get access to specific applications rather than the corporate network, with identity/context-based policies and application segmentation. Zscaler says ZPA brokers one-to-one connections between authorized users and apps rather than putting users on the network.

My 2026 shortlist

Independent 2026 comparisons similarly put ZPA, Prisma Access, Netskope and Cloudflare among the leading enterprise ZTNA platforms, while Twingate is particularly attractive for smaller organizations seeking straightforward VPN replacement.

Why I'd pick ZPA

The important architectural difference is:

Traditional VPN: User → VPN → Corporate network → Application

ZTNA: User → Identity/device verification → Authorized application

That matters because compromising a VPN account can potentially give an attacker broad network access and opportunities for lateral movement. ZTNA instead enforces least-privilege access to individual applications.

ZPA also makes sense if you're eventually planning to adopt a broader SASE/SSE architecture, rather than treating ZTNA as an isolated VPN replacement.

When I would not choose Zscaler

I'd choose Cloudflare One/Access instead if your priorities are simplicity, fast deployment, strong global connectivity, and cost efficiency. Cloudflare explicitly supports replacing VPNs with ZTNA and can provide both clientless access and client-based access to TCP/UDP/ICMP resources.

I'd choose Prisma Access if you're already a major Palo Alto customer, because consolidating your security stack can outweigh the differences between ZTNA products.

So, in short:

Best overall enterprise VPN replacement: Zscaler Private Access. Best alternative for simplicity/value: Cloudflare One. Best if you're a Palo Alto shop: Prisma Access. Best if you're Microsoft-centric: Entra Private Access. If you tell me your number of users, whether apps are on-prem/Azure/AWS, existing identity provider (Entra/Okta/etc.), and whether you need RDP/SSH/SMB/VoIP, I can narrow this to a specific recommendation and compare ZPA vs Cloudflare vs Prisma vs Entra on architecture, licensing, performance, and migration effort.
