Zero Trust Network Access

Zero Trust Network Access

Zero Trust Principles

Zero Trust Network Access (ZTNA) operates on the principle of 'never trust, always verify.' Unlike VPNs that grant broad network access, ZTNA provides application-level access based on identity, device posture, and context, minimizing attack surface.

Zero Trust Access

ZTNA Architecture

ZTNA solutions use broker-based architecture with clients connecting to access brokers that authenticate users, verify device security posture, and establish encrypted micro-tunnels to specific applications without exposing the network.

Identity-Centric Security

ZTNA enforces granular access controls based on user identity, role, device health, location, and time. Continuous verification ensures access privileges adapt to changing risk contexts, automatically revoking access when conditions no longer meet security requirements.

Benefits Over Traditional VPN

ZTNA offers superior security through least-privilege access, better user experience with direct-to-application connectivity, improved visibility and control, seamless cloud application support, and reduced attack surface compared to traditional VPNs.

Implementation Strategy

Adopt ZTNA gradually, starting with specific applications or user groups. Integrate with existing identity providers, define application access policies, deploy connectors or agents, and monitor adoption while maintaining VPN as backup during transition.
