Open to open source

Since its very beginning, Cyso has used open source software and owes a large part of its success to the efforts of the open source community. An important part of our servers has been using open source software for years, making it an essential part of our business. In order to make a contribution to the community ourselves, we have released some of our internal projects under an open source license.
