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.

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