OpenVPN

Business VPN and zero trust network access built on the open source OpenVPN protocol.

OpenVPN commercializes the protocol its founders released as open source in 2002, offering CloudConnexa, a hosted service, and Access Server, a self-hosted option, for secure connectivity between employees, sites, and applications. The products add ZTNA-style access controls on top of the widely audited protocol. The company has grown without outside funding.
