Platform Capabilities
Purpose-Built for OT Environments
OT/IT Convergence Monitoring
Monitor the convergence of IT and OT networks with unified visibility across Purdue model levels, detecting anomalous cross-zone traffic in real time.
SCADA & ICS Asset Discovery
Passively discover SCADA controllers, PLCs, RTUs, and HMIs without injecting traffic into sensitive OT networks or risking process disruption.
Network Segmentation Validation
Validate that network segmentation between IT, DMZ, and OT zones adheres to IEC 62443 standards and organizational security policies.
Vulnerability Management for OT
Identify vulnerabilities in OT firmware and protocols with risk scoring tuned for operational environments where patching windows are limited.
NIS2 Compliance for Essential Services
Map your OT security posture directly to NIS2 Article 21 requirements for essential entities operating critical infrastructure.
Air-Gapped Deployment Option
Deploy Gatekeeper in fully air-gapped environments with local data retention, ensuring compliance even in isolated operational networks.
