Pomerium is a zero-trust secure access vendor focused on identity-aware, context-aware application access without traditional VPNs. Its mission is to rethink access control for a world where networks can no longer be implicitly trusted, using a zero-trust reverse proxy to secure applications and services across teams, deployment models, and environments. Its portfolio includes the open-source Pomerium Core, Pomerium Zero with a hosted control plane and self-hosted proxy, and Pomerium Enterprise for larger organizations needing self-hosted deployment, centralized management, governance, and audit capabilities. The platform is designed for clientless access to internal web applications, databases, services, Kubernetes environments, and other protected resources, enforcing per-request authorization based on identity, device state, request context, and policy.
