ISO/IEC 27001 – Internal Audit Services
By Sherlocked Security – Qualified & Independent Auditors
Full Service Description
ISO/IEC 27001 is the global standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). An effective internal audit is essential to verify ISMS compliance, evaluate risk treatment effectiveness, and ensure readiness for certification and surveillance audits.
Sherlocked Security provides independent ISO/IEC 27001 Internal Audit services through the Make Audit Easy platform, helping organizations assess their information security posture and strengthen ISMS effectiveness.
Our internal audit methodology is risk-driven and evidence-based, covering both ISO/IEC 27001 management system clauses and Annex A controls. We evaluate governance practices, technical controls, and operational processes to ensure information security risks are identified, managed, and continuously improved.
The audit delivers clear, actionable findings that help management understand compliance status, address gaps, and enhance security controls—without disrupting business operations.
