Open-source licences
The third-party software in our package repository and the licence each one carries. Which of them are present on a given appliance depends on the product line and the configuration.
Written offer of source code
For each component listed below that is under the GNU General Public License, the GNU Lesser General Public License or the GNU Affero General Public License, we will provide the complete corresponding source code. Write to info@zedmos.com with the name and version of the component. You will receive the source on a customary medium or as a download, for a charge no more than the cost of performing the distribution. This offer is open to anyone who asks and stands for at least three years from the shipping of the release in question.
Licence texts
The full licence text of every component is available on request at info@zedmos.com, and is carried by the packages themselves. Nothing on this page and nothing in our terms limits the rights any of those licences grants you.
Shipped unmodified
We ship these components as their authors published them. Libraries under the LGPL are linked dynamically, so you can put a version of your own in their place. Should a component ever ship modified, the offer above expressly covers the source of that modified version too.
What is not third-party software
The Zedmos inspection engine, the Zero Trust Console and the firewall interface are our own work and are not under an open-source licence. They are governed by the Terms.
