Organisations are rapidly adopting new IT technologies in their OT environments as they embark on their digital transformation journey. The integration and increased connectivity between the two environments bring about new advantages such as increased productivity, efficiency, operations agility, as well as the ability for management to identify and capture next-generation business opportunities with the use of data analytics.


However, the IT and OT convergence has also brought about new cybersecurity challenges. With more OT devices and networks being connected to the internet, the attack surfaces of organisations have expanded. Consequently, organisations are now more exposed to new threat vectors that could potentially impact their critical OT systems such as Supervisory Control and Data Acquisition (SCADA) systems, Human-Machine Interfaces (HMI), Process Control Systems, and Safety Systems.

Ensign OT Cybersecurity Framework
Ensign’s approach is a comprehensive solution that follows a framework procedure to Identify, Protect, Detect, Respond and Recover in line with the NIST Cybersecurity Framework. Our end-to-end approach proactively secures your OT environment, detecting and mitigating cyberattacks before they compromise your systems.


  • Gain visibility over the OT environment to identify critical assets and high-risk assets that can be impacted by different cyber threats.
  • Prioritise risks, as well as communicate and recommend mitigation measures to management.



  • Implement secure-by-design and zero-trust architecture principles across IT and OT environments.
  • Manage access control policies, as well as third-party and staff remote connections to the OT environment.



  • Perform continuous monitoring and anomaly detection throughout the ICS cyberattack kill-chain
  • Reduce mean-time-to-detect threats through Ensign’s SOAR- and intelligence-driven SOC.





  • Develop Incident Response playbooks and Business Continuity Plans to enhance cyber resiliency.
  • Establish processes for timely restoration of critical operations and essential services affected by cybersecurity incidents.
Unique Value Proposition & Differentiators

Deep knowledge of IT and OT systems and architecture

We possess deep knowledge of OT environments through our partnerships with ICS vendors. This gives us an edge in implementing secure-by-design architectures with reference to ISA/IEC 62443 standards.

Solve challenges across the entire ICS cyberattack kill-chain

We manage cyber threats across IT and OT domains by taking a more holistic approach to identify risks, as well as detect and mitigate advanced cyber-attacks.

Customised technology solution architecture approach

We take an agnostic approach to technology, using only best-of-breed solutions that best fit our clients’ environments and needs—in collaboration with customers, vendors and extended partners.

Advanced hybrid IT/OT skillsets and expertise

Our subject matter experts are recognised with GICSP, CEH, ISA/IEC 62443, CISSP certifications, among others. These credentials enable us to implement and deliver global industrial cybersecurity projects.
