What is strongSwan?

strongSwan is an open-source framework that facilitates the implementation of the Internet Key Exchange (IKE) protocols, aimed at safeguarding IP traffic through both policy-based and route-based IPsec virtual private networks. It supports both IKEv2 and IKEv1 protocols, accommodates IPv4 and IPv6 tunnels, and includes features such as mobility, certificate and pre-shared key authentication, EAP methods, and a flexible plugin architecture for cryptographic, credential, and networking functions. This adaptable tool is highly regarded by network administrators and developers for building VPN gateways and interconnecting network endpoints, capable of handling everything from simple remote-access setups to complex IPsec configurations. Primarily designed for Linux systems, strongSwan has also been modified to work on other platforms such as FreeBSD, macOS, Windows, Android, and iOS, broadening its usability across a variety of devices. Furthermore, users can access an Android VPN client and a NetworkManager plugin specifically designed for Linux desktops, enhancing the overall user experience significantly. The source code is available under the GPLv2 license, with commercial licensing options for various components and specialized support services. To aid users in their journey, strongSwan provides extensive documentation covering installation, configuration, feature usage, and troubleshooting, which guarantees a seamless operational experience. Consequently, strongSwan stands out as a comprehensive solution for organizations in need of secure virtual private network implementations, offering both versatility and robust security features to meet diverse networking needs.

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.
