What does an ISO 27001 Lead Auditor do?

An ISO 27001 Lead Auditor independently assesses whether your ISMS meets the standard and demonstrably works in practice. They review the risk analysis, Statement of Applicability, controls, internal audits and management review, and report findings and recommendations.

What is the difference between an internal audit and a certification audit?

You carry out an internal audit yourself or through a hired auditor as part of your ISMS. A certification audit is performed by an accredited certification body and leads to the ISO 27001 certificate. A solid internal audit and pre-audit make the certification audit considerably smoother.

What does an ISO 27001 audit cost?

The cost depends on the scope, the number of locations, the maturity of the ISMS and the type of audit. Book a no-obligation audit scan for a suitable estimate.
