They  are also known as Security Analyst.

Grey Hats :-

Grey Hat Hackers are intermediate hackers who are explorers extending the boundaries for themselves. They will scan a system or network for a vulnerability but they don’t have malicious reasons for doing it. If any vulnerabilities they usually report to the owner of the system. The fact that they do all this without the permission of the owner makes it illegal.
