What is Zero Trust Network Access?

Traditional VPN and perimeter-based access control were built for a world where users and applications stayed inside the corporate network. Today’s enterprises with distributed, remote users, SaaS applications, and workloads across multiple clouds, require a fundamentally different approach.

Alkira’s ZTNA integrates zero trust access directly into your network architecture, without separate point products or complex integrations, delivering governed connectivity as one operating model, wherever users and applications reside.

FAQs


What is Zero Trust Network Access (ZTNA)?
+
ZTNA is a security model that eliminates implicit trust and grants access based on identity, device posture, and context. Instead of providing full network access, it ensures users can only access specific applications they are authorized to use.


How is Alkira ZTNA different from traditional solutions?
+
Alkira ZTNA delivers a unified zero-trust model across all traffic flows—including user-to-app, app-to-app, and user-to-internet—rather than focusing only on remote user access. This provides consistent security across the entire enterprise network.


Why is ZTNA better than VPN?
+
Unlike VPNs, which grant broad network access after login, ZTNA enforces least-privilege access and continuous verification. This reduces attack surfaces and prevents lateral movement within the network.


How does Alkira ZTNA support hybrid and multi-cloud environments?
+
Alkira ZTNA extends consistent security policies across on-premises, multi-cloud, and SaaS environments through a unified cloud networking platform—eliminating complexity while maintaining strong security and performance.
