ISO 27001 Guide 15: Surveillance Audit Best Practices

Surveillance Audit Best Practices

Quick Answer: Surveillance audits occur annually during your three-year certification cycle, examining selected controls and processes each year. Prepare by maintaining documentation, conducting regular internal audits, and addressing findings promptly. Minor nonconformities can escalate if not resolved, potentially risking your certification status.

Understanding Surveillance Audits

Surveillance audits occur annually after initial certification. They focus on selected areas rather than a full review, but preparation is still essential.

Annual Focus Areas

Each surveillance audit typically examines different controls and processes. Over three years, all major areas should be reviewed.

Preparation Strategies

Maintain readiness throughout the year rather than scrambling before audits. Keep documentation current and conduct regular internal audits.

Handling Nonconformities

Address surveillance audit findings promptly. Minor issues can escalate if not resolved, potentially jeopardizing your certification.
