OT Security

OT Cybersecurity & Managed Services

Securing operational technology — control systems, networks and connected assets — with assessment, segmentation, monitoring and ongoing managed support.

Protecting the systems that move real-world equipment.

Domain

OT, not just IT

Control systems, networks and connected plant

Model

Managed

Ongoing support rather than a one-off audit

Starting point

Asset inventory

You cannot protect what has never been listed

In practice

What this looks like on your asset

Operational technology fails differently from IT. A compromised control system does not leak data — it moves equipment, and the consequence is measured in production, safety and plant integrity rather than in records lost.

Work starts with discovery, because most OT estates have no complete inventory of what is connected. From there: architecture review, network segmentation, secure remote access, and monitoring tuned to industrial protocols rather than office traffic.

Delivered as a managed service, the controls stay current — patching, backup and change management continue after the assessment, which is where most OT security programmes quietly stop.

Scope of work

  • OT asset discovery and network inventory
  • Risk assessment and architecture review
  • Network segmentation and secure remote access
  • Continuous monitoring and anomaly detection
  • Patch, backup and change management for OT
  • Incident response planning and managed support

The rest of the portfolio

Most clients start with one service line and extend once the working relationship is proven.
