OT CYBERSECURITY
FRAMEWORK & ASSESSMENT
A critical infrastructure organization operating OT/ICS environments across multiple subsidiaries. Required a unified cybersecurity baseline and framework to strengthen compliance with regional and sector standards.
The client faced
- → Inconsistent OT security practices across sites
- → Unclear compliance requirements (IEC 62443, FIFA-2022, Qatar-NICS).
- → Network segmentation weaknesses
- → Outdated device configurations, and limited visibility into cyber risk.
- → Leadership lacked a clear roadmap to improve maturity and reduce operational exposure.
