Industrial Control System Security

Cyber-Physical Defense for Mission-Critical Operations

Industrial Control Systems (ICS) are the heartbeat of critical infrastructure—from energy and water utilities to manufacturing and transportation. As these systems grow more connected, they become more exposed to cyber threats that can cause real-world consequences. InfraShield delivers proven cybersecurity solutions purpose-built to secure the industrial technologies that keep your operations running.

Specialized ICS Security for OT and SCADA Environments

ICS environments were not designed for today’s threat landscape. They run on legacy equipment, require high availability, and often lack visibility or segmentation. InfraShield’s ICS security services focus on securing everything from PLCs to RTUs and critical OT endpoints—without disrupting the mission.

We help secure your industrial ecosystem by addressing:

ICS/ OT asset visibility and risk prioritization

SCADA protocol protection and network segmentation

Endpoint security for legacy and modern control systems

Remote access hardening and interconnection defense
