CrowdStrike sells cloud-based software that helps companies detect and stop cyberattacks on their computers and networks.
CrowdStrike is a cybersecurity company. It sells software that watches over a company's computers, servers, and cloud systems and tries to catch hackers before they do damage. Its main product is a lightweight program called the Falcon agent, which runs on each machine and sends clues about suspicious activity up to CrowdStrike's cloud, where the company's software decides whether it is an attack. A small team at a customer can then manage security for thousands of machines from one screen, without installing heavy old-style antivirus gear.
The idea that started the company is worth knowing. The founders believed that traditional antivirus software, which relied on spotting known bad files, was too slow, because a new piece of malware could slip past until someone wrote a signature for it. Instead, CrowdStrike watches behavior and shares what it learns across all its customers at once, so an attack seen at one company helps protect everyone else almost instantly. This "we all get smarter together" effect is a real advantage: the more customers it has, the more attack data it sees, and the better its detection gets. Customers pay a subscription, usually per computer protected, and often buy extra modules for things like identity protection or managed threat hunting. The company also sells incident response services—helping firms that have already been breached—and that work has brought it into some of the biggest hacking cases in recent years, including investigations into state-backed attacks. Competition is fierce, from giant platform vendors like Microsoft and Palo Alto Networks to smaller specialists, and Microsoft in particular has bundled security features into its products at low prices, which pressures everyone in the market.
CrowdStrike is a fast-growing, high-margin software business. In its fiscal year ended January 2025, revenue reached about $3.95 billion, up roughly 29% from the prior year. The messy part is real, though. In July 2024, a faulty software update crashed millions of Windows computers worldwide, grounding flights and disrupting hospitals and banks. The company apologized, fixed it quickly, and offered customer credits, but the episode showed how much the world now depends on a few security vendors—and how a single bad update at one firm can become everyone's problem.
