How do we secure your OT systems?

We've tailor made a risk management framework depending on your industry's safety risks


Five areas we examine to ensure system cyber security:

  • Design: Systems using modern technologies, including (TCP/IP), MODBUS and other standardised protocols, should be designed with security in mind as an integral part of your system

  • Development: Recognised secure software development standards exist that

  • should be used when developing software to be used within any environment

  • Installation: installation of the new or upgraded systems should not compromise the security that has already been put in place. It should not increase the attack surface that could be exploited by an attacker.

  • Maintenance: You should maintain systems throughout their life cycles to

  • ensure optimum functioning.

  • Decommissioning and Disposal: We decommission systems and dispose of them securely to prevent hostile 3rd parties acquiring your data

  • Independent Validation: ensuring security implementations and security

  • products have a level of assurance that has been tested
