Zero Trust Network Access (ZTNA)

Zero Trust is a security model that replaces legacy models that assumes anything inside a network is safe. Trust should never be assumed, and access is granted on a least-privileged basis.

ZTNA offerings help IT teams implement Zero Trust principles. They are based on a user-to-application model and provide secure granular access to internal applications and resources for remote users and devices based on identity, context, and policy. As a result, ZTNA is gaining popularity as a solution that can protect networks from today’s threats, especially as multi-cloud use and remote work continue to decentralize IT infrastructure and dissolve the traditional network perimeter.

ZTNA is a component of the Secure Access Service Edge (SASE) security model, which integrates multiple security services in a cloud-native platform.

In 2024, CyberRatings conducted independent tests of Zero Trust Network Access (ZTNA) offerings. The products were thoroughly tested to determine how they handled Authentication & Identity using Identity Providers, how the solutions handled Resource Access by limiting and blocking access to private (“hidden”) networks, how they handled Routing and Policy Enforcement, and support for TLS/SSL 1.2 & 1.3 cipher suites. For this test, CyberRatings tested up to 1 Gbps.
