Overview
SentinelOne’s Singularity Platform is built around Storyline, which its annual report describes as continuously linking process behaviour into contextual narratives that a behavioural AI model evaluates on the endpoint itself[6]. Because a Storyline records every unauthorised change made during an attack, the agent can remediate or roll back those changes with a single action, which the company presents as eliminating manual clean-up[6]. Storyline Active Response (STAR) lets users write custom indicator-of-compromise rules that run in real time, and Purple AI, a generative AI assistant, supports natural-language hunting and automated investigation[6]. The 10-K lists the tiers as Singularity Core (EPP replacing antivirus), Control (adds device and network control), Complete (the flagship EDR offering), Commercial and Enterprise, priced generally per endpoint[6]. The company is listed on the New York Stock Exchange; for the quarter to 31 July 2026 revenue grew 21% to US$292 million and ARR 22% to US$1.218 billion, with 1,715 customers above US$100,000 ARR[7]. Prices are not available on its own site to automated readers in this review, and the full EDR feature set requires the Complete tier or higher.
