OT cybersecurity support by role

For teams responsible for maintaining uptime, operational continuity, supportability, and safe change within live industrial environments. Typical concerns include system availability, remote access, unmanaged assets, backup arrangements, legacy infrastructure, supplier access, and the operational impact of cybersecurity controls.

For engineers and project teams who need cybersecurity requirements translated into clear and practical engineering decisions. Support includes architecture review, zones and conduits, supplier comment resolution, FAT/SAT evidence, interface assumptions, integration risks, and IEC 62443-aligned project documentation.

For OT security, network architecture, and cybersecurity teams working to reduce exposure across industrial control systems. Typical work includes asset visibility, network segmentation, firewall review, remote access control, vulnerability context, secure architecture review, and practical risk reduction within brownfield OT environments.

For teams who require clear, traceable evidence that cybersecurity requirements have been properly considered, implemented, reviewed, and closed out. Support includes audit-ready documentation, action tracking, evidence review, IEC 62443 alignment, CAF/NIS assurance support, and structured reporting for governance and project review activities.

For leaders who need a clear understanding of operational risk, project exposure, regulatory pressure, and proportionate cybersecurity investment priorities. Meridian helps translate technical findings into operational impact, business risk, project delay exposure, and practical next steps suitable for decision-making.

For suppliers and integrators responding to cybersecurity requirements within industrial control system projects. Support includes FAT preparation, evidence packs, cybersecurity documentation, design clarification, hardening evidence, review responses, and practical close-out of client comments and technical queries.
