What is CrowdStrike, the company linked to the global outage?

A global computer outage on Friday, impacting airports, banks, and other businesses, was partly attributed to a software update from US cybersecurity firm CrowdStrike. The issue stemmed from a defect in a single content update of CrowdStrike's Falcon software on Microsoft Windows operating systems. The company's engineers addressed the problem by advising customers to reboot their computers. The outage, not caused by a cyberattack, led to a 10% drop in CrowdStrike's stock in premarket trading. CrowdStrike, known for its cybersecurity services to many businesses and governmental agencies, has also been notable for investigating significant cyber incidents, including Russian interference in the 2016 US election.
