Licensing

While strongSwan is a true open source project, we offer alternative licensing schemes for many components, such as:

  • The core of the IKEv2 daemon
  • The libstrongswan crypto and utility library
  • Many plugins to extend the functionality of the daemon and the library

Licensing

strongSwan is licensed under the GNU General Public License version 2. Do you need a commercial license to integrate your own code into the IKEv2 components without licensing your extension under the GPL?

While the GPLv2 is sufficient for most partners, some prefer a commercial license. This allows you to keep your code closed for products you deploy, even if it is developed by us.

If you're interested in alternative licensing schemes, please contact us.
