About:
Perimeter 81 is a Zero Trust Network Access (ZTNA) client that replaces traditional VPNs with identity-aware, software-defined perimeter capabilities. It provides secure, granular access to corporate resources based on user identity, device posture, and context. The client enables seamless connectivity to cloud, on-premise, and hybrid environments while maintaining strict security policies.
Key Features:
  • Zero Trust Network Access (ZTNA) architecture
  • Identity and device-aware access controls
  • Split tunneling and traffic segmentation
  • Cloud-native and on-premise resource connectivity
  • Centralized policy management dashboard
Use Cases:
  • Secure remote access for distributed workforces
  • Replacing legacy VPN infrastructure with ZTNA
  • Segmented access to multi-cloud and hybrid environments
Alternatives:
  • Cloudflare Zero Trust – Similar ZTNA capabilities with broader CDN integration
  • Tailscale – WireGuard-based mesh VPN with simpler peer-to-peer architecture
  • OpenVPN – Traditional VPN solution without zero trust principles
