Why Work With Us?

How do we secure your OT systems?

We've a tailor made security risk management framework depending on your industry's safety risks. We assist you in development and delivery of cyber security and safety assurance case in accordance with your engineering management framework. 


Five key areas we examine to ensure systems 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 incl. COTS 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: We ensure security design, implementation and maintenance operation have a level of assurance in accordance with your engineering assurance framework.
