IT & OT Internal Audit Services
By Sherlocked Security – Qualified & Independent Auditors
Full Service Description
As organizations increasingly integrate Information Technology (IT) and Operational Technology (OT) environments, the risk landscape expands across cybersecurity, operational continuity, and safety. Converged IT–OT systems require robust governance and specialized controls to protect critical operations and digital assets.
Sherlocked Security provides independent IT & OT Internal Audit services through the Make Audit Easy platform to help organizations assess the effectiveness of security and operational controls across enterprise IT systems and industrial OT environments.
Our audit approach is risk-based and technically focused, evaluating governance frameworks, network architecture, cybersecurity controls, access management, system monitoring, and incident response capabilities across IT and OT domains. The assessment aligns with recognized standards such as ISO 27001, IEC 62443, NIST, and CIS Controls.
The audit delivers clear visibility into cyber and operational risks, along with practical, prioritized recommendations to strengthen resilience, protect critical infrastructure, and support compliance readiness.
