Access is granted based on verified user identity, device posture, and contextual information rather than network location. This limits exposure and ensures least-privilege access.

2. Application-specific access

Users connect only to the applications they need, reducing the risk of lateral movement and improving network security.

3. Continuous verification

Modern Zero-Trust Network Access providers continuously monitor sessions to detect anomalies, enforce policies, and maintain secure access dynamically.

4. Integration with SASE

By integrating with SD-WAN, CASB, and security service edge solutions, top ZTNA providers offer holistic protection while simplifying management.

5. Global performance and scalability

Solutions from leading providers, like Tata Communications, utilise a worldwide network of SASE points of presence to deliver low-latency access and scalable performance for distributed workforces.
