• Helping clients to understand their attack vectors that could be exploitable by threats.
• Designing secure OT network architectures and perimeter defences.
• Delivery of innovative security solutions to overcome security limitations of older OT systems.
• Authoring of OT specific policies, processes, and technical standards.
• Assurance of cyber transformation projects.
• Supporting the selection and development of security solutions and technologies.
• Designing OT remote access solutions.

What we’re looking for

• An understanding of OT products and systems, such as PLCs and SCADA.
• Understanding of the common cyber security challenges, cyber security controls and approaches within OT environments.
• Understanding of the different priorities of cyber security in OT & IT.
• Knowledge of cyber security frameworks, including but not limited to ISA/IEC62443, NCSC CAF, NIST SP 800-82, HSE OG86, ISO 27001.
• Awareness and understanding of the OT security threat landscape.
• Ability to understand and articulate the impacts of cyber security events in various OT environments.
• Experience in performing cyber risk assessments.
• Familiarity with asset discovery, vulnerability analysis, and threat detection tooling.
