About Meridian
Engineering-led OT cybersecurity for brownfield control environments
Meridian Consultants supports industrial operators, automation projects and critical infrastructure teams with control system assurance, project lifecycle evidence and proportionate risk reduction in live operational environments.
Who Meridian is
Meridian focuses on the intersection of industrial automation, operational risk, project assurance and cybersecurity evidence. The consultancy is positioned for teams that need clear engineering outputs, not generic IT security commentary.
Engineering-led support for industrial control systems, automation projects and operational technology environments where uptime, safety and maintainability matter.
Practical and proportionate recommendations shaped around live environment constraints, legacy assets, supplier dependency and brownfield implementation.
Standards-aware methodology using IEC 62443 concepts such as systems under consideration, zones, conduits and verification evidence without implying certification.
Documentation-focused delivery so project teams, operations, suppliers and assurance stakeholders can understand decisions and close evidence gaps.
