CrowdStrike was founded in 2011 to fix a fundamental problem : The sophisticated attacks that were forcing the world’s leading businesses into the headlines could not be solved with existing malware-based defenses. Founder George Kurtz realized that a brand new approach was needed — one that combines the most advanced endpoint protection with expert intelligence to pinpoint the adversaries perpetrating the attacks, not just the malware.

There’s much more to the story of how Falcon has redefined endpoint protection but there’s only one thing to remember about CrowdStrike : We stop breaches.
