In an analysis piece called 'Assessing the Scope of the CrowdStrike Endpoint Detection and Response Incident,' FireEye noted that there was a surge in the number of newly detected threats, which involved CrowdStrike's updated software. Approximately 850 million Windows devices worldwide were affected by this update, affecting less than 1% of all Windows installations. This incident, therefore, showcases the immediate impact on ongoing defenses and availability, demonstrating the business reliance on CrowdStrike's services for managing numerous security threats.
