About

DEFION’s OT Security Baseline Assessment provides a clear, independent evaluation of your OT environment, validating existing measures and identifying practical improvements to strengthen resilience.

Key Benefits

DEFION assesses your OT security posture with mapping, validation, and benchmarking against IEC 62443 and CRA. Practical recommendations with minimal disruption.

How It Works

  1. Mapping – Identify and document OT networks, assets, and risks.

  2. Validation – Review and test existing documentation, security measures, and controls.

  4. Benchmarking – Compare current practices against IEC 62443, the CRA, and relevant industry regulations.

  5. Process Review – Evaluate governance aspects such as access management, supplier management, update processes, and incident handling.

  6. Recommendations – Deliver practical, risk-based improvements adapted to your organization’s environment and resources.
