There are many automated DAST & SAST tools but from my perspective, there is no tool that can give you fully automated penetration testing, as most of the pentesting efforts are manual and depend on the professional and their way of thinking.
Also, you can use a variety of…
SAST - Veracode, goes well with integration
DAST - Either Microfocus Webinspect or Burp Suite Professional or OWASP ZAP (Open Source)
Component Scanning - Blackduck or Sonatype Nexus Platform or Whitesource Bolt
Vulnerability Auditing - Nessus & CIS - CAT ( Assessor Pro) or…
Yes OWASP ZAP is a good option as it's an open source so always preferred but Burp Suite Pro will give you more options, its one of the best tool to have for pentesters so defo worth it.
