OT cybersecurity assessment and secure network validation
Our flagship engagement. We take your network as found, assess it against the standards, threat-model it, prove the weaknesses in the cyber range, and hand back a prioritised hardening plan — one standard process, one report, evidence throughout.
One standard process, from requirements to report
Every assessment follows the same six steps, so you know exactly what you are commissioning and exactly what comes back. The whole engagement is delivered on the Synapse platform: your network becomes a structured, queryable model, and every finding traces to the asset, zone or conduit it concerns.
- Requirements — scope, operational constraints and standards obligations captured up front
- As-found assessment — the network modelled as it actually is: assets, flows, zones, addressing
- Threat modelling — attack paths, exposed conduits and the consequences that matter to your operation
- Security baseline — the as-found network measured against IEC 62443-3-3 and NIST SP 800-82
- Cyber range testing — the network replicated in our range and put under test
- Hardening plan & report — a prioritised programme of security activities, with the evidence behind it
Proven in the range, not argued on paper
Paper assessments produce opinions; the cyber range produces evidence. We replicate your network in our range and test the design under realistic attack conditions — so the report distinguishes weaknesses that are exploitable from ones that are theoretical, and the hardening plan is prioritised by demonstrated risk rather than checklist order.
What you receive
The engagement returns a single, complete report — plus the living model behind it, which you keep and can re-check whenever the site changes.
- Zone-and-conduit diagram and full asset inventory
- Threat model with attack paths and consequence analysis
- IEC 62443-3-3 / NIST SP 800-82 baseline and gap analysis
- Cyber-range test findings with reproduction evidence
- A prioritised, costed programme of hardening activities
Frequently asked questions
What is an OT cybersecurity assessment?+
A structured evaluation of an operational-technology network's security posture: how the network is actually built, what threats apply to it, how far it falls short of the required baseline (IEC 62443, NIST SP 800-82), and what to fix first. Ours adds cyber-range testing so the findings are demonstrated, not assumed.
What do we need to provide?+
Typically network drawings, asset lists, switch and firewall configurations, and access to the engineers who know the site. We build the as-found model from what exists — incomplete or out-of-date documentation is normal and part of what the assessment corrects.
Do you need to touch the live network?+
No. The assessment is built from documentation, configurations and interviews, and the testing happens against a replica of your network in our cyber range — so protection, control and SCADA traffic are never put at risk.
Who is the assessment for?+
EPCs, systems integrators and engineering firms that outsource secure network validation, and asset owners who need an independent, standards-based view of a site before commissioning, after a change, or ahead of an audit.
