Pomerium provides a zero-trust reverse proxy, securing application access where traditional network trust is obsolete. Its products, Pomerium Zero and Enterprise, facilitate clientless remote access and scalable self-hosted deployments. The platform authenticates and authorizes access for human users, internal services, and AI agents, applying granular, policy-driven controls across diverse infrastructures.
Robert DeSimone founded Pomerium in 2019, driven by the need to rethink access control for modern, untrusted networks. His background, including selling his startup Surelock to BeyondTrust and extensive experience in Privileged Access Management, equipped DeSimone to build a contemporary access security framework.
The company serves organizations requiring secure internal, contractor, and time-bound access. Pomerium further secures internal APIs, Kubernetes environments, and AI agent interactions. Its vision is to establish a comprehensive access paradigm, enabling organizations to operate safely and efficiently as network perimeters dissolve.
