OT Cyber Security Assessments

Conducting OT Cyber Security Assessments is vital to identify vulnerabilities, understand potential risks, and develop strategies to manage and reduce the impact against cyber threats. Secolve’s OT Cyber Security assessments cover various levels of organisational detail – from high-level strategic risks to detailed technical gap analyses – and include evaluations of third-party and supply chain vulnerabilities using industry standards and frameworks. 

Risk Assessments 

Risk assessments identify, quantify, and prioritise potential threats to OT systems at strategic, technical, and system levels. They help organisations understand vulnerabilities, mitigate third-party risks, and proactively defend against threats, enabling informed, risk-based decisions.

High-level (Strategic) Risk Assessments 

Low-level (Technical) Risk Assessments

System Level (Detailed) Risk Assessment 

Third Party and Supply Chain Risk Assessments 

OT Threat Assessments

Gap Assessments

Gap assessments compare an organisation’s OT security practices against industry frameworks and standards like NIST, AESCSF, and ISA/IEC 62443. These assessments identify improvement opportunities against industry best practice, providing a clear understanding towards improving compliance, and enhancing overall security posture.

Readiness Assessments

Readiness assessments evaluate the preparedness of business units, divisions, or critical assets to meet regulatory requirements and industry standards, such as SOCI and AESCSF. These assessments enable organisations to quickly identify their current state at a high level and prioritise their next steps towards achieving compliance obligations and reaching their targeted cyber security posture.
