FAQ

Questions about OT cybersecurity?

Here are some of the questions organisations commonly ask before starting an OT security assessment.

What is an OT cybersecurity assessment?+

An OT cybersecurity assessment evaluates the security posture of industrial environments, including assets, network architecture, communications, vulnerabilities, security controls and operational risks.

Why is OT cybersecurity different from IT cybersecurity?+

Industrial environments have different operational constraints. Availability, safety, legacy systems, specialised protocols and process continuity must be considered alongside traditional cybersecurity requirements.

What does an assessment include?+

The scope can include asset visibility, network architecture, segmentation, vulnerability exposure, security controls, remote access, industrial protocols and alignment with recognised OT cybersecurity practices.

Can Sentra OT work with IEC 62443?+

Yes. IEC 62443 can be used as a reference framework to assess industrial cybersecurity controls and identify practical opportunities for improving the security posture of OT environments.

Will the assessment affect production?+

The approach is designed around the operational constraints of industrial environments. Assessment activities are planned to minimise disruption and avoid unnecessary impact on critical production systems.

What do we receive after the assessment?+

The outcome is designed to provide a clear picture of the current security posture, the most relevant risks and a prioritised roadmap of recommended improvements.

Can Sentra OT support remediation?+

Yes. Beyond the initial assessment, Sentra OT can provide advisory support to help organisations prioritise remediation activities, improve security architecture and strengthen their OT cybersecurity programme.

How do we start?+

The first step is a short conversation about your industrial environment, objectives and current security challenges. From there, we can define an appropriate assessment scope.
