OT/ICS security architecture
Segmentation between IT and OT environments designed around actual plant and grid topology, not generic network diagrams.

Critical Infrastructure
Cyber-physical security for energy, water, transportation, and the operational technology that keeps essential services running.
Critical infrastructure operators carry a risk that most industries don't: a successful attack doesn't just cost data, it can cost power, water, or physical safety. Ransomware groups increasingly treat OT environments as high-leverage targets precisely because downtime is not an option for operators — which makes them more likely to pay, and more attractive to attack. Cyberpert's critical infrastructure practice is built around the reality that IT and OT security require different assumptions, different tooling, and different recovery priorities.
What makes this sector different
- Operational technology and industrial control systems that were never designed with internet-era threat models in mind
- IT/OT convergence that expands the attack surface faster than most security teams can adapt
- Zero tolerance for unplanned downtime, which limits how aggressively patching and monitoring can be applied
- Ransomware actors who specifically target infrastructure operators because outages create maximum leverage
- An expanding patchwork of regulation (NIS2, sector-specific directives) with real penalties for non-compliance
How Cyberpert supports this sector
Continuous OT-aware monitoring
Detection tuned for industrial protocols, with alerting that distinguishes operational anomalies from genuine threats.
Incident response for cyber-physical events
Response playbooks that account for safety systems and physical consequences, not just data recovery.
Supply chain and vendor remote-access review
Hardening of the third-party and remote-maintenance access paths that are now the most common OT entry point.
Regulatory compliance mapping
Control evidence aligned to NIS2 and sector-specific critical infrastructure directives.
Tabletop exercises for operations and safety teams
Crisis simulations that bring IT, OT, and physical safety teams into the same room before a real incident does.
Frameworks and authorities we build against
NIS2 Directive
IEC 62443
NIST Cybersecurity Framework for critical infrastructure
