ABOUT VEGA
Vega is an open source platform to test the security of web applications.

inadvertently disclosed sensitive information, and other vulnerabilities.
It is written in Java, GUI based, and runs on Linux, OS X, and Windows.


Vega includes an automated scanner for quick tests and an intercepting proxy for tactical inspection.
