Some projects require the extra freedom of Open Source platforms

Our R&D team creates one and only one software platform, the Centreon platform, which combines an Open Source core with commercial extensions.

We distribute the core framework of this Centreon platform under GPLv2 and Apache Open Source licenses. We’re proud of this Centreon Open Source project that we started in 2005 and is now used by over 200,000 IT Professionals all over the world! So proud that the exact same Open Source core powers all our Commercial editions.

We know from experience that some organizations need the extra freedom of Open Source software to create a bespoke IT Ops environment while others value the packaging and extra functionalities of commercial editions.
