SentinelOne, Inc.
SentinelOne, Inc. operates as a cybersecurity provider in the United States and internationally. The company's Singularity Platform delivers an artificial intelligence-powered autonomous threat prevention, detection, and response capabilities across an organization's endpoints, cloud workloads, and identify credentials, which enables seamless and autonomous protection against a spectrum of cyber threats. It also offers generative AI-security agent (Purple AI), security information and event management, endpoint security, cloud security, identity security, exposure and vulnerability management, and threat services. The company was formerly known as Sentinel Labs, Inc. and changed its name to SentinelOne, Inc. in March 2021. SentinelOne, Inc. was incorporated in 2013 and is headquartered in Mountain View, California.
What does it do?
SentinelOne makes software that protects businesses from hackers and cyberattacks. Think of it like a very smart security guard that watches every computer, server, and cloud system in a company at once. Instead of waiting for a human to notice something suspicious, SentinelOne's AI detects and stops threats automatically — sometimes in milliseconds. If a hacker tries to install ransomware on a hospital's computers, SentinelOne's software can block it before any damage is done.
Cyberattacks are at an all-time high, and companies of every size are being forced to spend more on protection — making cybersecurity one of the few areas of tech spending that is genuinely recession-resistant. SentinelOne sits at the intersection of two massive trends: the explosion of AI-powered tools and the growing complexity of keeping hybrid cloud environments secure. With regulations tightening globally and data breaches costing companies millions, the question for most businesses is no longer whether to buy this kind of software, but which vendor to trust.
How does it make money?
SentinelOne makes almost all of its money through subscriptions — businesses pay an annual or multi-year fee to use its Singularity Platform across their devices and cloud systems. Revenue grew from $0.8B to $1.0B in the latest year, a roughly 25% increase, which shows strong customer demand. The company also sells add-ons like Purple AI (its generative AI security assistant) and data management tools, which let it charge more per customer over time. Like many fast-growing software companies, it is still losing money — net loss of $0.5B last year — as it spends heavily on sales and engineering to win market share.
Why do investors care?
The core growth story is that SentinelOne is taking customers away from older, slower security tools — most notably CrowdStrike and legacy players like McAfee — by offering a more modern, AI-first platform. Investors are betting that as AI threats become more sophisticated, only AI-native defenders can keep up, and SentinelOne is built from the ground up for that world. For the thesis to work, the company needs to keep growing revenue quickly, expand how much it earns from each customer (called net revenue retention), and eventually turn its losses into profits as the business matures.
