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 has a collaboration with Amazon Web Services (AWS) to deliver unified AI governance for customers building on Amazon Bedrock. 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 computers, company networks, and cloud systems from hackers — automatically, without a human having to press a button. Think of it like a security guard that never sleeps and can spot a threat in milliseconds. When a hacker tries to break into a company's systems, SentinelOne's software detects and stops the attack in real time. It works across laptops, servers, and even cloud infrastructure — basically anywhere a company stores or processes data.
Cyberattacks are getting more frequent and more expensive, which means companies can't afford to skimp on security — making SentinelOne's market recession-resistant in a way most tech companies aren't. AI is also changing the game: SentinelOne is one of the few cybersecurity companies using AI natively to automate threat response, not just as a marketing buzzword. Investors are watching to see whether it can take market share from the dominant player, CrowdStrike, which stumbled badly in mid-2024 after a software update crashed millions of Windows machines worldwide.
How does it make money?
SentinelOne makes almost all of its money through subscriptions — companies pay an annual fee to use its Singularity Platform, and the more endpoints (devices, servers, cloud accounts) they protect, the more they pay. Revenue grew from $0.8 billion to $1.0 billion in the latest year, a roughly 25% increase. It also sells add-on products like Purple AI, its generative AI security assistant, and data services that help companies investigate past incidents. The challenge is that while revenue is growing, the company is still losing money — it spent roughly $0.5 billion more than it earned last year.
Why do investors care?
The core growth story is simple: cybersecurity spending is rising every year, and SentinelOne is taking a bigger slice of a growing pie. Its AI-powered platform is genuinely differentiated — it can respond to threats autonomously, which appeals to companies that don't have large in-house security teams. The 2024 CrowdStrike outage gave SentinelOne an unexpected opening, as security teams began looking for alternatives. For the thesis to work, SentinelOne needs to convert that opportunity into long-term customers, scale efficiently, and eventually turn its losses into profits.
