A review of your industrial network architecture, zones and conduits, remote access and IT–OT boundaries against IEC 62443.
We assess how your control networks are structured and connected, where IT and OT meet, how vendors access systems remotely and whether critical safety systems are properly isolated.

What’s included
Every OT Architecture Review engagement is scoped to your systems, risks and team, with clear outcomes agreed before work starts.
Asset and traffic mapping without active scanning of sensitive controllers.
Findings mapped to IEC 62443 security levels and requirements.
Recommendations that respect uptime, certification and safety constraints.
In industrial environments, availability and safety come first. Our OT specialists understand control systems and work with engineers to reduce cyber risk without disrupting production.
Learn the plant, processes and safety constraints with your engineers.
Build an inventory of controllers, HMIs, networks and remote connections, passively.
Evaluate risk and controls against IEC 62443 and NIST SP 800-82.
Deliver improvements in planned maintenance windows with full engineering sign-off.
