About The Product Group

The Counter Adversary Operations (CAO) Team is a first-of-its kind team that brings together CrowdStrike Falcon® Intelligence and the CrowdStrike® Falcon OverWatch™ threat hunting team to disrupt today’s adversaries and ultimately raise their cost of doing business. Both threat hunting and intelligence operations are essential to detect, disrupt and stop today’s adversaries. CrowdStrike Counter Adversary Operations has the power of both — along with the trillions of telemetry events from the AI-powered CrowdStrike Falcon® platform — to quickly act and intensify its impact on adversary activity. CrowdStrike’s deep adversary knowledge, expertise in pursuing and stopping threats, and visibility derived from the Falcon platform make us uniquely qualified to deliver the most effective method of stopping breaches and protecting customers.
