OT cybersecurity advisory purpose-built at the intersection of IEC 62443 and the SOCI Act — where technical security meets regulatory obligation.
Two principles underpin every port254 engagement.
IEC 62443 is the only international standard purpose-built for securing industrial control systems. Every assessment, recommendation, and remediation roadmap we deliver is anchored to it — not ISO 27001 adapted for OT, not a generic framework stretched to fit. We hold ISA/IEC 62443 Expert certification across all four domains: fundamentals, risk assessment, system design, and maintenance.
The SOCI Act is in force. CIRMPs are mandatory. CISC has moved from education into active assurance and audit. We understand the CIRMP Rules, the CISC audit cycle, and what board attestation actually requires — and we build that into every engagement so clients aren't managing two separate programs.
port254 engagements are delivered by practitioners certified across the full OT security lifecycle — from governance and risk assessment through to offensive security and system design.
