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.

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.
