Pomerium

Pomerium is an open-source identity-aware proxy built around zero trust principles that provides secure, clientless access to internal applications without a VPN. The platform continuously verifies user identity, device state, and request context before granting access, offering a modern alternative to traditional perimeter-based security. Founded on the premise that access control requires fundamental rethinking in a world where networks can no longer be trusted, Pomerium serves millions of requests daily for thousands of users across organizations of all sizes, from startups to Fortune 500 companies.
