Conducting frequent pentests is vital to maintaining an excellent security posture as they often uncover vulnerabilities that are not covered by standard vulnerability scans by employing the methodologies used by malicious actors.
Similarities between internal and external testing
Whilst internal and external pentests differ in scope, they share a similar approach and methodology. Including the following:
