IronWASP

IronWASP is an open source, powerful scanning engine that aims at vulnerability testing in Web applications (like SQL injections, XSS, etc), and supports both Python and Ruby scripts. It supports further extensibility by allowing plugins or modules written in Python, Ruby, C# or VB.Net to be incorporated with the source. The simple GUI and advanced scripting support add to this efficient tool’s appeal.
