What is OpenVPN Access Server?

OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution that runs inside your own environment — on-prem or your AWS, Azure, or GCP account — keeping tunnel traffic and configuration off any third-party network. Access is scoped to the application, not the IP or subnet: each user is routed only to the specific app they're authorized for, identified by domain name, with nothing else on the network visible to them. That makes lateral movement structurally impossible, not just restricted by policy. Access Server Link turns setup into a guided flow (hostname, cloud, region, password), with SSL certificates provisioned and renewed automatically, eliminating manual certificate handling as a source of risk. Because entitlements are bound to hostname rather than IP, they hold up through IP changes and autoscaling with no manual rework. Your instance remains entirely under your control, giving you the data ownership and audit trail needed for HIPAA, SOC 2, and GDPR — full control of the stack, delivered with SaaS-level ease. Administration happens through a browser-based portal instead of SSH: users, certificates, and access rules are managed without shell access, narrowing your attack surface. The Zero Trust App Broker routes each connection through a placeholder IP tied to a single authorized app — the real destination stays hidden, so a stolen credential offers no way to scan or reach other systems. Least privilege is built into the architecture, not left to policy that can drift. Native clients cover Windows, macOS, iOS, Android, and Linux, keeping identity- and app-based controls consistent across every endpoint. Templated deployment on AWS, Azure, and GCP means security teams get standardized, auditable rollouts rather than one-off manual builds.

What is Libreswan?

Libreswan is an open-source software that provides a robust implementation of IPsec and the Internet Key Exchange (IKE), enabling the establishment and management of secure virtual private networks. It supports both IKEv1 and IKEv2 protocols, facilitating the negotiation of security associations between multiple systems through IPsec while incorporating features such as certificate-based authentication and NAT traversal capabilities. Designed to operate as a network service on Linux and various BSD operating systems, it leverages the existing IPsec stack available in the host environment. Network administrators can efficiently configure connections and manage credentials using configuration files and command-line interfaces, while the built-in ipsec utilities allow for effective monitoring of tunnel statuses. Libreswan’s ability to connect with other compatible IPsec peers makes it ideal for both site-to-site and remote-access VPN setups. This software is an essential asset for network administrators and security professionals who need to configure and maintain IPsec VPN gateways or endpoints, thereby ensuring secure communication across various networks. Additionally, its open-source nature not only promotes transparency but also empowers users to tailor the software to suit their unique requirements, thus enhancing its adaptability in diverse deployment contexts. Ultimately, Libreswan stands out as a versatile solution that addresses the growing need for secure network communications in today's digital landscape.
