SentinelOne doesn't need to beat CrowdStrike to work, because cybersecurity is large enough for multiple winners and should keep growing as AI adds agents, cloud workloads and autonomous software that need protecting. It already has more than $1.2 billion of ARR, 20%-plus growth and improving margins. Its growth is the slowest of the group today, but if it remains a major security platform over the next decade, its current valuation leaves a lot of room. x.com 

SentinelOne appears undervalued relative to its expected revenue growth. Analysts forecast 19.2% NTM revenue growth, versus 23.2% for CrowdStrike, which trades at a premium on forward EV/sales. x.com 

Security software is arguably more of an AI bubble than semiconductors. Firms are bid up to nosebleed multiples on moderate AI-related revenue acceleration while facing medium- to long-term risks from Microsoft, Google and the AI labs and a 10-year Treasury yield above 5%. Their forward P/Es rest on non-GAAP earnings that exclude large stock compensation. A reversal could come from results missing high buy-side bars, security share gains by Microsoft or Google, or AI lab security launches. x.com  … Show more

SentinelOne is an often overlooked cybersecurity play that is nearly profitable and has two recent upgrades. Its chart shows a bullish scallop pattern, with the next move expected above 20.7. x.com 

Cybersecurity is now an essential layer of the AI theme, as agentic AI makes fraud prevention, digital identity and enterprise security indispensable. CrowdStrike found an 89% year-over-year rise in attacks by AI-enabled adversaries, and SentinelOne forecasts AI-powered phishing will exceed 42% of global intrusions in 2026. The Amplify Cybersecurity ETF is up 43% this year and the Global X Cybersecurity ETF 44%, against 16% for the Nasdaq. x.com 

SentinelOne is a pathetic company because it still runs -23% GAAP margins at about $1B of ARR while growing roughly 20%. Comparable software companies grew 40%+ at that scale while losing less money on a GAAP basis. Per @Sam_Badawi, Q4 revenue rose 20% to $271.2M and ARR 22% to $1.12B, with FY2027 revenue guided to $1.195-1.205B. x.com  x.com  x.com 

SentinelOne is objectively one of the best cybersecurity software companies ever, and its incompetent management is why it trades at only 4x ARR. Few software companies ever reach $1B of ARR, fewer are still growing 20%+ at that scale, and fewer still can be bought at 4x ARR. Its -23% GAAP margin, raised by @davey_juice, is not great. x.com  x.com  x.com 

Cybersecurity stocks have a powerful long-term tailwind because more AI means more complexity, more attack surface and more need for security. CrowdStrike, SentinelOne, Palo Alto Networks, Zscaler, Fortinet, Okta and Rubrik moved up strongly premarket after Anthropic CEO Dario Amodei published an essay arguing the AI industry should slow down, with Anthropic committing to give third-party evaluators permanent access to verify its safety measures. The market may be connecting those dots. x.com 

SentinelOne should be growing far faster on about one-fifth of CrowdStrike's revenue, yet its growth keeps slowing. Revenue grew 20% versus CrowdStrike's 23%, billings growth slowed to 11.7%, $100k+ customer additions fell and retention slipped to 109% versus about 115% at CrowdStrike. The GAAP net loss widened to $110M, free cash flow is negative and net margin has not improved since 2024. SBC is 29% of revenue, the share count rose 4.2%, and buybacks make no sense with negative free cash flow. … Show more

SentinelOne's growth is solid and profits are starting to pour in, yet the stock trades at only 5x forward sales. It reported $56M of net new ARR, with total ARR of $1.218B, up 22% year over year. Matching CrowdStrike's net new ARR jump would have required about $65M; per @SergeyCYW, CrowdStrike added a record $333M, up 50.5%. x.com  x.com  x.com
