A security audit is another service that many cybersecurity companies offer as a means of checking whether the client’s systems are adequately protected or not.

While the goal of this service and penetration testing is the same, the method used is different. Penetration testing seeks to identify weaknesses by trying to breach the scoped out network or device. On the other hand, systems auditing is done to check whether the client’s cybersecurity policies, protocols, and technologies are compliant with the legal requirements and industry standards. 

An expert can only perform these audits due to the detailed, highly technical, and evolving regulations set by relevant agencies and governments.  

For instance, most health insurance companies conduct a HIPAA (Health Insurance Portability and Accountability Act) audit to check off technical, physical, and administrative safeguards, employee training, and enforcement of the set standards.
