01
IEC 62443 methodology
Gap assessment, zoning, and control design against IEC 62443, with safety and production constraints treated as hard requirements.
Sector focus
OT/ICS security for energy, ports, water, and telecom operators.
Critical infrastructure security is constrained by safety and uptime. Difaa delivers IEC 62443 OT/ICS assessments with passive-first discovery, IT/OT segmentation, secure remote access, and OT-aware monitoring. Where transactions reshape national assets, cyber diligence and post-deal hardening connect to the same operating reality.
Where we help
