Sentinel One

Market position

SentinelOne is a publicly traded endpoint and enterprise security vendor and a Russell 1000 component, described in media as a Silicon Valley CrowdStrike competitor and as larger than Wiz in revenue and headcount at the time of their 2023 dispute, though its market capitalization fell roughly 80% in the two years after its 2021 IPO. The company reports repeated placement as a Leader in the Gartner Magic Quadrant for Endpoint Protection Platforms and recognition in the IDC MarketScape for SIEM and the Latio Security Market Report, and it is AV-TEST certified.

SentinelOne positions its patented behavioral AI and autonomous, machine-speed detection and response as differentiators from traditional signature-based antivirus, delivering endpoint, identity, cloud, and AI protection through a single lightweight agent and unified console with deployment flexibility across SaaS, on-premises, hybrid, and air-gapped environments. The company states it was the first pure cybersecurity vendor to introduce agentic and generative AI into its platform, and it cites the Prompt Security integration for runtime AI security across browsers, desktop applications, and APIs, including MCP gateway coverage of more than 13,000 known MCP servers.

Technology

The platform applies machine learning and a patented behavioral AI heuristic model to monitor endpoints, IoT devices, and cloud workloads, providing real-time detection, automated response, and remediation via a single agent. Additional components include Singularity Identity for identity threat detection and response, cloud security/CNAPP capabilities, an AI SIEM and data analytics layer (Scalyr, and pending Observo AI pipeline technology that ingests, enriches, summarizes, and routes telemetry with claimed data-volume reduction up to 80%), and Purple AI plus agentic workflows for triage, correlation, and routine response. Prompt Security adds runtime GenAI protection with policy-based controls, prompt-injection and data-leakage prevention, model-agnostic coverage across providers such as OpenAI, Anthropic, and Google as well as self-hosted models, and MCP gateway security.

Go-to-market

SentinelOne markets through direct sales, partners and channel resellers, industry-specific solution packaging, product demos, and its own conference, OneCon (OneCon26 scheduled for October 20-22 in Las Vegas). It has used reseller and technology-integration partnerships (for example the 2023 Wiz re-sell agreement, later terminated, and a CyberArk identity integration) and publishes threat research through SentinelLABS, annual threat reports, and analyst recognition to support demand generation.

Enterprises and organizations across industries worldwide, including global enterprises and smaller security teams; named customers referenced on the company site include the Golden State Warriors, Norwegian Airlines, and Aston Martin Lagonda. Buyers include CISOs, IT leaders, and SOC analysts.

Geography

Headquartered in Mountain View, California, with offices in Boston, Prague, Tokyo, and Tel Aviv. The company is frequently described in media as Israeli-founded or Israeli-based, has customers worldwide, and offers its website in multiple languages including German, Spanish, French, Italian, Japanese, Korean, Dutch, and traditional Chinese.

History

SentinelOne was founded in 2013 as Sentinel Labs, Inc. by Tomer Weingarten, Almog Cohen, and Ehud ("Udi") Shamir, and was renamed SentinelOne, Inc. in 2021. It raised a $120 million Series D led by Insight Partners in June 2019, a $200 million Series E in February 2020 at roughly a $1.1 billion valuation, and a $267 million round in 2020 at a $3.1 billion valuation. The company completed an IPO on the NYSE on June 30, 2021, raising $1.2 billion under the ticker S. It acquired Scalyr (2021, $155 million), Attivo Networks (2022, $616.5 million), Krebs Stamos Group (2023, relaunched as PinnacleOne), PingSafe (2024, valued above $100 million), Prompt Security (announced August 2025, reported at about $250 million), and announced an agreement to acquire Observo AI (September 2025). In 2023 it terminated an exclusive reseller partnership with Wiz and, per Reuters, retained Qatalyst Partners while weighing a sale; in July 2025 reports described advanced acquisition talks with Palo Alto Networks at an $8-10 billion valuation, which was not officially confirmed.

Risks & controversies

SentinelOne's market capitalization declined roughly 80% in the two years following its 2021 IPO, prompting reports that it hired Qatalyst Partners to explore a sale and repeated takeover speculation (Wiz in 2023, Palo Alto Networks in 2025). Its exclusive partnership with Wiz was terminated in 2023 amid public acrimony, with a non-competition clause reportedly restricting both parties from selling competitors' products. In April 2025 the Trump administration ordered an investigation into Chris Krebs, whom SentinelOne had hired through the Krebs Stamos Group acquisition, and suspended the company's security clearances pending a national-interest review; Krebs subsequently resigned. The company remains unprofitable, reporting a $288 million net loss for fiscal 2025, and pending acquisitions carry integration and closing risks.
