GIAC Response and Industrial Defense

GRID

The GIAC Response and Industrial Defense (GRID) certification validates your ability to defend Industrial Control Systems (ICS) using Active Defense strategies. It proves you understand how ICS-specific attacks inform mitigation, and that you can apply network security monitoring, digital forensics, and incident response in operational technology environments. For ICS incident responders, SOC analysts, and security professionals protecting critical infrastructure, GRID demonstrates real-world readiness to detect, respond to, and contain threats targeting industrial networks.
