Cyber Assurance

Rail cyber security

Protecting rail systems from cyber risk

We help train operators, suppliers and OEMs understand cyber risk, build security into rail systems and provide clear evidence of assurance.

Support shaped around your business

Our support is tailored to the systems you operate, the products you supply and the evidence you need to provide.

Understand risk and maintain assurance

We help operators understand their operational technology, manage cyber risk and maintain assurance as systems and threats change.


Map assets and interdependencies

Build a clear view of systems, connections and critical dependencies.


Assess and manage risk

Create risk assessments that can be reviewed and reused through engineering change.


Set strategy and improvement plans

Turn priorities into an achievable OT cyber security roadmap.


Strengthen supplier assurance

Develop contract schedules, assess suppliers and set clear security expectations.


Test, respond and improve

Scope penetration testing, respond to findings and update assurance evidence.

Build security in and evidence it

We help suppliers and OEMs embed cyber security in their products and give customers confidence in the result.
