OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) and business VPN solution that gives organizations full control over their own secure network. It's software organizations deploy directly into their own environment — on-premises hardware or their own cloud account on AWS, Azure, Google Cloud, or others — with tunnel traffic flowing directly between users and the server. With Access Server Link, teams can go from zero to a fully configured deployment in minutes: point-and-click setup across AWS, Azure, and GCP, automatic SSL certificate provisioning and renewal, and a web-based admin portal for managing users, certificates, and access — no SSH or manual DNS work required. Access is granted per application and per identity using domain names rather than broad network-level access, so users only reach what they're explicitly permitted to, and lateral movement is structurally blocked.
