Rating the Running Plant: IEC PAS 62443-2-2:2025 and the Security Protection Rating

Deep End Era. Engineering with Sankalp · Oct 28, 2026 · 56m

Two years after start-up, the Al Sahil Gas Complex's board asks a simple question: how secure is the plant, today, as operated? Its OT security lead Khalid Mansour has security levels from the design phase and a stack of vendor certificates, but nothing that describes the plant as it actually runs. Plant auditor Noor Haddad thinks the 2025 Publicly Available Specification IEC 62443-2-2 is the missing piece. Part six of The Deep End's 62443 series follows them through their first security protection rating.
