What Is a Cyber Security Audit?

A Cyber Security Audit is a structured review of an organisation’s cyber security controls, policies, systems and processes to identify weaknesses, measure effectiveness and improve overall security posture.

Cyber security audits help organisations understand where risks exist, whether controls are operating effectively and what improvements should be prioritised to reduce cyber threats.

Cyber Security Audit Explained

Many organisations invest in cyber security products without fully understanding whether their controls are configured correctly or providing adequate protection.

A cyber security audit provides an independent review of your security environment and identifies opportunities to strengthen protection against cyber attacks.

A cyber security audit answers three key questions:

What security controls do we have?
Are they working effectively?
What improvements should be made?
