Cyber Security for Operational Technology
Boosting cybersecurity resiliency for Operational Technology (OT) is an essential proactive strategy to safeguard critical assets, operations, and the overall business success of an organisation.
OT encompasses systems that control and manage physical processes, such as manufacturing, energy production and transportation. Cybersecurity is crucial for OT because breaches in these environments could lead to operational disruptions, safety risks and large financial losses.
Many OT systems control processes with direct safety implications, such as power generation and transportation. Robust cybersecurity helps to maintain the safety of workers, the public and the environment. There are also numerous regulations and standards which require certain levels of cybersecurity in OT environments to show compliance.
Arcanum’s highly qualified and widely experienced OT Team can help your organisation to holistically identify and mitigate your risk appropriate to your business goals and objectives.
We can help you with every aspect of the process, from identifying and prioritising the risks your systems or processes face, to creating and validating policies and procedures, and ensuring that all the mitigations are considered and chosen within your specific business context to give maximum risk reduction in the most efficient means.

Organisations from all sectors may need to comply with cyber security regulations and standards. This can include the Health and Safety Executive (HSE) OG86, the Network and Information Systems (NIS) Regulations or the National Cyber Security Centre’s (NCSC) Cyber Assessment Framework (CAF).
Our OT Risk Assessments align to the Detailed Risk Assessment methodology laid out in ISA/IEC 62443-3-2. This is a process of identifying and evaluating the security risks that may affect the OT environment and can help to establish a security baseline.
Cyber Security Management System (CSMS)
The CSMS is for managing cyber security risk used in the ISA/IEC 62443 standard. It is a methodology for securing your OT environment and helps to define your organisation’s cyber security strategy. It can also be aligned with other regulations and standards such as the NIST Cyber Security Framework.
An Audit provides key stakeholders with a view of your business’ cyber security maturity and allows you to understand your cyber security posture. We are independent and vendor-agnostic, providing a clear and accurate audit capability in-line with relevant industry standards and regulations.
Network Architecture Review
Understanding OT architecture is an important step in all phases of the lifecycle of OT systems, including the design and implementation of systems, maintaining the components and systems, and scaling up or expanding operations as efficiently and effectively as possible.
Arcanum’s CREST accredited penetration testing team are experienced with performing both vulnerability assessments and penetration tests in OT environments. Penetration tests play an important role in assurance and strengthening your OT environment’s security.
Supply Chain Risk Management
The Supply Chain is often the most common threat vector into an organisation. Your own cyber security may be top-notch, but what about your supply chain? Having an understanding, awareness, and control of your supply chain risk is crucial in ensuring your business’ own cyber security.
