Hello,
I will provide full thorough vulnerability analysis of you website , web service or api. The tests will be very thorough and will also test any 0day vulnerabilities. I will provide you a detailed vulnerability report after the tests which will contain all the vulnerabilities, their probable causes and the ways to remove them.
Just try once for the safety of your website. I have 15 years experience in vulnerability analysis. The work will be of top class.
Thanks
