The best ZTNA solution is usually a dedicated ZTNA platform for private app access, unless the organization is ready to buy a full SASE stack. ZTNA platforms give users access to specific applications, not the whole network, which cuts risk from stolen credentials and unmanaged devices. SASE is broader and often better for secure web access, cloud controls, branch security, and remote access in one package.
TLDR: ZTNA is the cleaner replacement for legacy VPN when employees, contractors, and partners need controlled access to private apps. For example, a 600 person software company could reduce contractor onboarding from three days to under one hour by assigning app level policies instead of VPN groups. In many deployments, help desk tickets also drop because users no longer need to connect, disconnect, and retry a slow VPN client. SASE is best when the same company also wants web filtering, CASB, firewall as a service, and centralized security policy.
What makes a ZTNA platform “best”?
A strong ZTNA platform should make access tighter and user work simpler. That sounds obvious, but many tools still make admins click through five screens to change one policy. Honestly, it feels like some products were built to impress auditors more than help security teams run clean access.
The best ZTNA solutions usually include:
- Application level access: Users reach only approved apps, not full subnets.
- Identity based policy: Access depends on user role, group, device, location, and risk.
- Device posture checks: The platform checks patch status, OS version, disk encryption, EDR, and compliance.
- No inbound exposure: Private apps stay hidden from the open internet.
- Good user experience: Login should feel close to single sign on, not a daily obstacle.
- Useful logs: Security teams need clear records of who accessed which app, when, and from what device.
- Simple policy design: Naming, grouping, and rule testing should be easy to understand.
Top ZTNA solution types
ZTNA products fall into several practical groups. The right pick depends on company size, app hosting, compliance needs, and existing security tools.
- Standalone ZTNA platforms: These focus on secure private app access. Examples include Twingate, Zscaler Private Access, Cloudflare Access, Appgate, and Perimeter 81 by Check Point.
- SASE based ZTNA: These include ZTNA as one part of a larger cloud security service. Examples include Netskope, Palo Alto Prisma Access, Cato Networks, Cloudflare One, and Zscaler.
- Endpoint led zero trust access: These pair access decisions with endpoint security. Microsoft Entra Private Access and Cisco Secure Access can fit this model well for existing Microsoft or Cisco shops.
- Open source or self managed options: These can work for technical teams, but they often require more upkeep, more monitoring, and stronger in house skills.
ZTNA platforms vs SASE
ZTNA is a feature set. SASE is a larger security model. This is the main difference.
A ZTNA platform secures access to private apps. SASE usually bundles ZTNA with secure web gateway, cloud access security broker, firewall as a service, data loss prevention, DNS filtering, and sometimes SD WAN.
SASE makes sense when an organization wants to replace several security products at once. It can reduce vendor sprawl and give one policy layer for users, branches, cloud apps, and private resources. The downside is cost and rollout time. Expect to waste time on policy cleanup if old firewall rules, VPN groups, and web filtering rules are messy.
A standalone ZTNA platform makes sense when the main problem is remote access. It is often faster to deploy and easier to test with one business unit. A team can start with sales access to CRM admin tools, engineering access to Git servers, or contractor access to ticketing systems.

VPNs still work, but they give too much trust too quickly. Once connected, a user may see broad network ranges unless rules are carefully locked down. That creates a larger blast radius after credential theft or device compromise.
ZTNA changes the model. The user does not “join the network.” The user gets access to one approved application through a brokered connection. If the device fails posture checks, access can be blocked or limited. If the user changes location or risk score rises, the session can be challenged again.
VPN often wins on legacy compatibility. Some older systems expect network level access, fixed routing, or thick client behavior. ZTNA may need connectors, app mapping, and testing. Still, for modern private web apps, admin portals, internal tools, and developer services, ZTNA is usually cleaner.
ZTNA vs other zero trust alternatives
Zero trust is not one product. ZTNA is one control within a larger program. Several alternatives or companion tools may be needed.
- IAM: Identity and access management controls users, groups, single sign on, and multi factor authentication. It is essential, but it does not replace private app access control.
- PAM: Privileged access management protects admin accounts, secrets, and elevated sessions. It is vital for IT and DevOps teams.
- NAC: Network access control manages devices on office networks. It helps with campus security, but it is not ideal for remote private app access by itself.
- Microsegmentation: This limits east west movement inside data centers and cloud workloads. It pairs well with ZTNA.
- Endpoint security: EDR and device management help prove whether a device is healthy enough for access.
How to choose the best ZTNA solution
Security teams should start with the apps, not the vendor slide deck. The first question is simple: which private apps need protection, and who needs them?
- For small and mid sized teams: Cloudflare Access, Twingate, and Perimeter 81 can be strong picks due to simpler setup and friendly admin controls.
- For large enterprises: Zscaler Private Access, Netskope Private Access, Palo Alto Prisma Access, and Cisco Secure Access offer scale, reporting, and deeper security integrations.
- For Microsoft heavy environments: Microsoft Entra Private Access may fit well with existing Entra ID, Conditional Access, and Intune policies.
- For branch plus remote security: Cato Networks, Prisma Access, Cloudflare One, and Netskope are worth review because they cover more than private app access.
The buyer should test real workflows. A pilot should include at least one private web app, one SSH or RDP use case, one contractor group, and one unmanaged device scenario. If policy changes take too long or logs are vague, that pain will grow after rollout.
Common ZTNA mistakes
The biggest mistake is copying VPN groups into ZTNA without rethinking access. That only recreates old risk in a newer tool. ZTNA works best with smaller app based policies.
Another mistake is ignoring user experience. If access adds ten extra seconds to every app launch, users will complain and find workarounds. Good ZTNA should feel nearly invisible after login.
Logging also matters. A weak audit trail makes incident response harder. Security teams need session details, policy decisions, device posture data, and integration with SIEM tools.
FAQ
What is the best ZTNA solution?
The best choice depends on the environment. Standalone ZTNA tools such as Twingate, Cloudflare Access, and Zscaler Private Access are strong for private app access. SASE platforms such as Netskope, Prisma Access, Cato Networks, and Cloudflare One are better when broader cloud security is needed.
Is ZTNA better than VPN?
For most remote access use cases, yes. ZTNA gives access to specific apps instead of the full network. VPN may still be needed for some legacy systems.
Is ZTNA the same as SASE?
No. ZTNA controls access to private applications. SASE includes ZTNA plus tools such as secure web gateway, CASB, firewall as a service, and SD WAN.
Can ZTNA replace MFA?
No. ZTNA should use MFA as part of identity verification. MFA confirms the user, while ZTNA controls which apps that user can reach.
Who needs ZTNA most?
Organizations with remote workers, contractors, cloud hosted private apps, admin portals, or strict compliance needs benefit most. It is also useful for reducing risk after VPN related security incidents.
