SentinelOne, Inc. (S): A Bull Case Theory

We came across a bullish thesis on SentinelOne, Inc. on Shareholdersunite Essentials’s Substack by Shareholdersunite. In this article, we will summarize the bulls’ thesis on S. SentinelOne, Inc.'s share was trading at $17.72 as of July 17^th. S’s forward P/E was 84.03  according to Yahoo Finance.

SentinelOne is a cybersecurity company pioneering the world’s first AI-powered Extended Detection and Response (XDR) platform designed to make cybersecurity defense autonomous. It addresses a generational shift in security as digital transformation, AI adoption, and an expanding attack surface outpace legacy solutions and outstrip available cybersecurity talent.

Modern cyberattacks are increasingly fast, stealthy, and AI-enhanced, exploiting complex hybrid environments and overwhelming human analysts with alert volumes. Legacy tools relying on signatures, manual monitoring, or limited historical data struggle to detect and neutralize these threats, while cloud-only or on-premise-only solutions often fail to meet enterprises’ hybrid deployment and compliance requirements.

SentinelOne’s Singularity Platform unifies prevention, detection, and automated response across endpoints, cloud workloads, identities, IoT, and unmanaged devices. It ingests and correlates petabytes of data in real-time, building dynamic behavioral “Storylines” via distributed Static, Behavioral, and Streaming AI models that operate locally and in the cloud. When threats are detected, the platform autonomously stops attacks and rolls back unauthorized changes, minimizing disruption.

Purple AI, SentinelOne’s generative AI engine, replicates expert analyst reasoning, automating threat hunting, investigation, and remediation through natural language queries. The Singularity Data Lake, flexible deployment options, and multi-OS parity underpin its broad, integrated security architecture.

Growth is driven by innovation, a “land-and-expand” model with 110% net retention, global expansion, and strategic acquisitions that strengthen cloud and advisory offerings. Competing with leaders like CrowdStrike and Palo Alto Networks, SentinelOne differentiates through AI-driven autonomy, platform breadth, and speed, offering enterprises a comprehensive defense aligned with modern cybersecurity demands.

Previously we covered a bullish thesis on SentinelOne, Inc. (S) by Matthew | Sycamore Capital in March 2025, which highlighted accelerating revenue growth, expanding AI-driven offerings, and its milestone shift to profitability. The company’s stock has depreciated about 8% since then as ARR growth was hit by retiring a legacy product. The thesis still stands as Shareholdersunite shares a similar view but emphasizes the Singularity Platform’s autonomous capabilities.
