Perimeter 81 is a Zero Trust Network Access (ZTNA) client that replaces traditional VPNs with identity-aware, software-defined perimeter capabilities.

The client enables seamless connectivity to cloud, on-premise, and hybrid environments while maintaining strict security policies.

Key Features:

Identity and device-aware access controls
Split tunneling and traffic segmentation
Cloud-native and on-premise resource connectivity
Centralized policy management dashboard
