Perimeter 81

Perimeter 81 provides a client application that connects macOS devices to a zero‑trust network‑as‑a‑service platform. It establishes encrypted tunnels and enforces identity‑based access policies, allowing users to reach corporate resources without relying on traditional VPNs. The software is designed for organizations that need to protect internal applications and data while granting remote workers secure, per‑request connectivity.

The client runs natively on macOS, integrating with the operating system to route traffic through the service and apply the configured security rules. It supports the core features of the zero‑trust model, such as continuous verification of user and device posture, and it can be managed centrally through the provider’s dashboard.

As a stable release, the application is intended for production use in environments where consistent, reliable secure connectivity is required across macOS endpoints.
