A security audit is a systematic, measurable assessment of how an organisation’s security protocols align with established benchmarks. 

These audits scrutinise the efficiency and effectiveness of an organisation’s information systems, ensuring that necessary safeguards are in place to protect against internal and external vulnerabilities. 

The goal is to identify gaps and weaknesses and provide actionable recommendations to fortify these systems. In essence, a security audit is a diagnostic tool that aids in upholding an organisation’s integrity, confidentiality, and availability of its digital assets.
