Overview

What is Pomerium?

Pomerium is an identity-aware proxy that enables secure access to internal applications. Pomerium provides a standardized interface to add access control to applications regardless of whether the application itself has authorization or authentication baked-in. Pomerium gateways both internal and external requests, and can be used in situations where you'd typically reach for a VPN.

Pomerium can be used to:

• provide a single-sign-on gateway to internal applications.
• enforce dynamic access policy based on context, identity, and device state.
• aggregate access logs and telemetry data.
• a VPN alternative.

Architecture

In action

To make this a bit more concrete, see the following short video which demonstrates:

1. An unauthorized user authenticating with their corporate single-sign-on provider (in this case Google)
2. The unauthorized user being blocked from a protected resource.
3. The unauthorized user signing out from their session.
4. An authorized user authenticating with their corporate single-sign-on provider.
5. Pomerium delegating and grating access to the requested resource.
6. The authorized user inspecting their user details including group membership.
