ZAP (Zed Attack Proxy) is a dynamic application security testing tool published under the Apache License. When used as a proxy server it allows the user to manipulate all of the traffic that passes through it, including HTTPS encrypted traffic. It can also run in a daemon mode, which is then controlled via a REST-based API.
ZAP was originally forked from Paros which was developed by Chinotec Technologies Company. [2] Simon Bennetts, the project lead, stated in 2014 that only 20% of ZAP's source code was still from Paros. [3]
The first release was announced on Bugtraq in September 2010, and became an OWASP project a few months later. [4] [5] In 2023, ZAP developers moved to the Linux Foundation, where they became a part of the Software Security Project. [6] [7] [8] As of September 24, 2024, all of the main developers joined Checkmarx as employees, and ZAP was rebranded as ZAP by Checkmarx. [9]
ZAP was listed in the 2015 InfoWorld Bossie award for "The best open source networking and security software". [10]
