Compass Security is developing security tools on regular basis. I for myself created a plugin/extension for Burp Intercepting Proxy called BurpSentinel. It can makes some tedious manual testing more automated, and helps identifying security vulnerabilities in web applications like XSS weaknesses or SQL injections. Compared to fully automated scanners (like the one already integrated into Burp), it has the advantage that the tester is able to see which requests have been performed and what their answer is, and also the difference to the original response. Therefore it is not only possible to know what exactly has been tested and how, but also the side-effect can be more effectively gauged. Also the amount of false negatives and false positives can be better judged. BurpSentinel is under constant development, and is available on Github here.
