Compliance audits are a key part of governance and risk management. They help organizations confirm that operations align with expectations and identify areas where improvements may be needed.

What a Compliance Audit Involves

A compliance audit typically includes reviewing documentation, examining processes, and testing whether controls are functioning correctly. This may involve:

Purpose of a Compliance Audit

  • Identify gaps or weaknesses in controls
  • Improve processes and documentation
  • Demonstrate accountability to regulators or stakeholders

Audits are often part of an ongoing cycle of review and improvement rather than a one-time exercise.
