Question

Are there any SQL injection tools out there so I can test my site for vulnerabilities? Any good ones? Free ones would be good.

Answer 1

If it is non-commercial (free only for non-commercial use), http://www.nessus.org/nessus/ offers some really good web-app SQL injection tests. It also tests for XSS, and hundreds of known vulnerabilities as well. It helped me find a hole or two.
