ZAP was originally forked from Paros which was developed by Chinotec Technologies Company. Simon Bennetts, the project lead, stated in 2014 that only 20% of ZAP's source code was still from Paros. The first release was announced on
Bugtraq in September 2010, and became an
OWASP project a few months later. In 2023, ZAP developers moved to the
Linux Foundation, where they became a part of the Software Security Project. As of September 24, 2024, all of the main developers joined
Checkmarx as employees, and ZAP was rebranded as ZAP by Checkmarx. ZAP was listed in the 2015
InfoWorld Bossie award for "The best open source networking and security software". ==Features==
