Perimeter 81 is a cloud-based zero-trust network access (ZTNA) platform that replaces traditional VPNs for remote workforces — offering software-defined networking, micro-segmentation, and identity-based access controls. Unlike traditional VPNs (all-or-nothing network access), Perimeter 81 grants access per-application based on user identity and device posture. Used by 3,000+ businesses including IBM and Booz Allen Hamilton. Acquired by Check Point in 2023.

The verdict
Our take on Perimeter 81
Best zero-trust network security for growing businesses replacing traditional VPN with per-application access controls. Perimeter 81's ZTNA architecture serves companies where remote employees accessing all internal systems through a single VPN tunnel creates over-permissive network access — IT teams at 100-500 person companies choose Perimeter 81 because micro-segmenting access to HR systems, financial tools, and development environments prevents a compromised laptop from accessing all internal systems.
