Hardening SCADA Systems Against State-Sponsored Actors

Challenge: A critical national infrastructure operator needed to validate the resilience of its Operational Technology (OT) and SCADA systems against highly sophisticated, state-sponsored APTs. Solution: INTUISCO LTD deployed a highly specialised APT Emulation, mimicking known state-actor TTPs targeting industrial control systems. This involved deep dives into network segmentation and defensive architecture. Result: Uncovered critical vulnerabilities in their OT network's perimeter and internal segmentation. Our recommendations led to immediate hardening, dramatically reducing their attack surface and increasing their resilience against nation-state level cyber threats, ensuring operational continuity.
