Funding

[edit | edit source]

In June 2019, SentinelOne received $120 million in a Series D funding round led by Insight Partners.[11] The company received an additional $200 million in Series E funding in February 2020.[14] The Series E round placed SentinelOne at a valuation of about $1.1 billion.[4][3] In 2020, SentinelOne closed a round for $267 million in funding, bringing its total valuation to $3.1 billion.[15]

On June 30, 2021, SentinelOne completed an initial public offering on the NYSE, raising $1.2 billion.[16] It trades under the symbol S, which was formerly used by telecommunications company Sprint prior to its 2020 merger with T-Mobile US.

Acquisitions

[edit | edit source]

In February 2021, SentinelOne announced the acquisition of cloud-scale data analytics platform Scalyr for $155 million in cash and equity.[17]

In March 2022, SentinelOne announced the acquisition of the identity detection and response technology company, Attivo Networks, for $616.5 million in cash and equity.[18]

In early November 2023, SentinelOne acquired[19] the boutique consultancy Krebs Stamos Group, founded by former CISA Director Chris Krebs and former Facebook Chief Security Officer Alex Stamos, which was rebranded and relaunched[20] as PinnacleOne Strategic Advisory Group.[21] In April 2025, Chris Krebs resigned from the company after being targeted by the Trump Administration in an executive order.[22]

In January 2024, SentinelOne agreed to acquire PingSafe, valuing the company at over $100 million.[23]

In August 2025, SentinelOne announced a definitive agreement to acquire Prompt Security, an Israeli startup focused on securing AI in runtime and preventing data leakage from generative AI tools, for an estimated $250 million in cash and stock.[24][25] The acquisition extends SentinelOne's Singularity Platform to secure the rapidly growing use of generative and agentic AI in the workplace, providing real-time visibility into AI tool usage, automated enforcement to prevent prompt injection and sensitive data leakage, and protection against AI-specific threats. The deal closed in SentinelOne's third fiscal quarter of 2025.

In September 2025, SentinelOne announced its intention to acquire Observo AI, an AI-native real-time data pipeline platform that specializes in streaming data for telemetry pipeline management.[26] The transaction is expected to close in SentinelOne's third fiscal quarter of 2025 through a combination of cash and stock, subject to regulatory approvals and customary closing conditions. Observo AI's platform ingests, enriches, summarizes, and routes data across enterprises before it reaches a SIEM or data lake, with the capability to reduce data volume by up to 80% while maintaining access to complete logs when needed. The acquisition aims to accelerate SentinelOne's AI SIEM strategy and advance their vision of autonomous security operations centers (SOCs).
