Critical Infrastructure & OT Cybersecurity
Critical infrastructure increasingly depends on interconnected IT, OT, communications, cloud services and third-party systems. The security objective is therefore not simply to prevent intrusion; it is to understand operational consequences, reduce attack pathways and maintain essential services through disruption.
Asset visibility and critical dependency mapping
Identify OT assets, supporting IT systems, communication paths, third-party dependencies and the systems whose failure could have the greatest operational consequence.
IT/OT segmentation and security boundaries
Design meaningful zones and controlled conduits so that operational communications are limited, understood and monitored.
Remote and privileged access
Strengthen vendor and administrative access with strong identity, least privilege, controlled sessions, logging and time-bound permissions.
Legacy and difficult-to-patch environments
Use risk-based compensating controls where immediate replacement or patching is operationally impractical.
Incident response and recovery
Prepare coordinated IT/OT response procedures, recovery priorities, operational communications and tested restoration arrangements.
Governance and cyber resilience
Bring engineering, cybersecurity, management and vendor stakeholders into a common risk-management framework.
