Behind a massive IT failure that grounded flights, upended markets and disrupted corporations around the world is one cybersecurity company: CrowdStrike Holdings.

Known as a dominant supplier of software that protects businesses from ransomware attacks, CrowdStrike was thrust into the spotlight on Friday as it struggled to fix a faulty patch that led to cascading, system-wide failures, paralyzing the operations of clients ranging from banks to global retail giants to health-care systems on Friday. 

CrowdStrike was founded by former executives of antivirus pioneer McAfee and launched in 2012. It has grown into the leading maker of a relatively new type of security software that’s considered among the best defenses against ransomware and other hacking threats. It controls about 18% of the $8.6 billion global market for so-called “modern” endpoint protection software, just ahead of archrival Microsoft, according to market research firm IDC.
