OT Security Assessment

Identify and prioritise security gaps across plants, industrial networks, and connected control systems before they affect uptime, safety, or production continuity.

Exfinity uses an assessment approach designed for live industrial environments, with scope, timing, and testing methods agreed before activity begins.

The Challenges

OT systems are connecting more closely with enterprise IT, cloud services, and remote access tools. Limited asset visibility, older equipment, third-party access, weak network separation, and incomplete incident readiness can increase operational risk.

Industrial environments cannot be treated like standard IT systems. Security work must consider production dependencies, availability, safety, vendor access, and the consequences of disruption while still giving leadership a clear view of risk.

The Solution

Exfinity assesses asset visibility, connectivity, access, governance, third-party exposure, and incident readiness using carefully planned and non-disruptive methods.

Asset Discovery and Visibility: Map OT, ICS, and SCADA assets, communication, connectivity, and dependencies.

Segmentation and Access Review: Assess IT-OT boundaries, network design, privileged access, and remote vendor pathways

Configuration and Vulnerability Review: Evaluate system configurations and weaknesses using passive and controlled methods agreed in advance.

Governance and Incident Readiness: Review policies, monitoring, response, recovery, third-party risk, and physical exposure.

What is an OT security assessment?

It is a structured review of cybersecurity risk across operational technology, industrial control systems, SCADA, and supporting networks.

Will the assessment disrupt production?

The engagement is planned around live environments. Scope, methods, timing, and permitted validation are agreed before activity begins.

How is OT security different from regular IT security?

OT assessment considers industrial systems, production dependencies, control networks, availability, and operational consequences that require a different risk lens.

What systems can be covered?

The agreed scope may include PLCs, RTUs, HMIs, SCADA systems, historians, engineering workstations, and supporting network infrastructure.

What do we get at the end?

You receive prioritised findings linked to operational and business risk, with practical recommendations for decision-makers and technical teams.
