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.
