Stakeholder
OT & Cybersecurity Teams
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.
What you are likely dealing with
OT cybersecurity work lands differently depending on the responsibility you hold. These are the practical pressures this role often has to balance.
- asset visibility
- network segmentation
- architecture weaknesses
- vendor access
- unsupported devices
- monitoring gaps
- evidence quality for risk decisions
Technically mature, architecture-focused support for understanding OT exposure, improving trust boundaries, and producing evidence that engineering teams can act on.
How Meridian helps
- Assess OT network architecture, trust boundaries, remote access, and critical communication paths.
- Build evidence that helps prioritise exposure reduction across legacy and brownfield environments.
- Support segmentation strategy, asset visibility improvement, and practical control selection for OT constraints.
- Create outputs that cyber, engineering, and operations teams can use in the same decision process.
- trust boundaries
- segmentation
- network architecture
- risk reduction
- remote access control
- OT exposure reduction
Typical deliverables
Outputs are shaped around engineering evidence, review close-out, and decisions that can be used by operations, projects, assurance, or supplier teams.
- OT architecture and exposure review
- Asset and interface register
- Segmentation options paper
- Remote access review
- Prioritised exposure reduction action plan
