Active Asset Discovery for Complete OT Visibility and Threat Detection

Smart Polling™ extends Guardian’s built-in asset discovery functionality with active capabilities that deliver comprehensive and precise details about each asset in your network.

The add-on module for Guardian™ uses precise, active technologies to identify non-communicating assets, giving you visibility into rogue devices that don’t belong. And, it gathers extensive information about all assets, including operating system, firmware, patch levels and more, to help you identify weak spots before they’re exploited.
