Vega is a free and open source, gui-based, multi-platform and extensible scanner and testing platform to test the security of web applications.
Vega can help you find and validate SQL Injection, Cross-Site Scripting (XSS), 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. The Vega scanner finds XSS (cross-site scripting), SQL injection, and other vulnerabilities.
Vega includes a website crawler powering its automated scanner. Vega can automatically log into websites when supplied with user credentials.
Vega can be used to observe and interact with communication between clients and servers, and will perform SSL interception for HTTP websites.
The Vega proxy can also be configured to run attack modules while the user is browsing the target site through it. This allows for semi-automated, user-driven security testing to ensure maximum code coverage.
Vega is still early-stage software.
