Our verdict on AetherGuard

AetherGuard is an OT, ICS and IoT security platform for mid-market and enterprise teams protecting industrial networks and connected-device environments. Its passive approach inventories devices from network traffic, while protocol inspection, behavioral anomaly detection and ICS threat detection provide visibility into activity. It is a fit for teams that need to understand device exposure and attack paths without making active discovery the core of their inventory process.

The platform’s deeper value is in connecting network visibility to operational risk. It assesses vulnerabilities and exposure, maps attack paths across the Purdue model, and scores assets by criticality, exploitability and physical consequence. Teams can simulate segmentation policies against observed device flows before applying changes. Fingerprinting extends visibility to unmanaged IoT and IIoT devices, and a security copilot is grounded in telemetry. These functions make AetherGuard more than an inventory tool; they support analysis of how weaknesses and device relationships could affect industrial operations.

Deployment options include cloud, self-hosted and air-gapped environments, with an edge sensor described as operating autonomously offline. Optional virtual patching, access control and containment add response measures, though they are not presented as universal core controls. Pricing is handled through contact with sales rather than published plan tiers. AetherGuard suits OT teams looking for asset discovery, attack-path analysis and policy planning in industrial settings. Organizations seeking a straightforward device inventory product, or published pricing for a self-service purchase, should consider alternatives.
