About strongSwan

strongSwan is an open-source implementation of the Internet Key Exchange (IKE) protocols for securing IP traffic with policy- and route-based IPsec virtual private networks. It supports IKEv2 and IKEv1, IPv4 and IPv6 tunnels, mobility, certificate and pre-shared-key authentication, EAP methods, and a modular plugin system for cryptography, credentials, and networking. Network administrators and developers use it to build VPN gateways and connect network endpoints, from remote-access setups to complex IPsec deployments. The core software runs on Linux and has been ported to FreeBSD, macOS, Windows, Android, and iOS. An Android VPN client and a NetworkManager plugin for Linux desktops are also available. The source code is licensed under GPLv2, with commercial licensing available for most components and separate commercial support options. Documentation covers installation, configuration, features, and troubleshooting.
