CheckMarx has been used an application to scan the applications to rectify vulnerability in the code and to check the security lapses. I have been using checkMarx to check the same in my .NET application and have found checkMarx to be great use. I would like to mention few good things about the same .
1.) It has support to many languages . In my case it can find the lapses in C#, Java script, J query , Typescript .
2.) The description is quite clear about the issues which makes it easier to understand the problem statement behind the security lapse.
3.) The online community present for CheckMarx is quite good which makes it easier to find the resolution Review collected by and hosted on G2.com.
