This is one of best software which I have used to scan an API for security issues, it's performance also very good as compare with any other tool available in market like nikto web server. Testing tools this has some UI problem that makes difficult when we want do test by click, but still its not much easy, because every thing was done so simple way..It always give us accurate results related scanning ..its just amazing....it worth paying money you can't find anything bad about red huntβ¦
