How Meridian helps

Support focus

  • Translate OT cybersecurity requirements into clear engineering scope, boundaries, and design assumptions.
  • Review zones, conduits, remote access paths, package interfaces, and supplier deliverables before acceptance points.
  • Support IEC 62443-aligned thinking without turning project delivery into a generic IT compliance exercise.
  • Help engineering teams produce evidence that can support design review, FAT, SAT, handover, and close-out.

Useful language for this role

  • zones and conduits
  • SuC definition
  • remote access architecture
  • segmentation strategy
  • vendor package integration
  • FAT/SAT cybersecurity evidence
  • engineering assurance

Typical deliverables

Outputs are shaped around engineering evidence, review close-out, and decisions that can be used by operations, projects, assurance, or supplier teams.

Typical outputs

  • System under consideration definition
  • Zone and conduit model
  • Design review comments and close-out tracker
  • FAT/SAT cybersecurity evidence checklist
  • Requirements and evidence matrix
