SentinelOne (NYSE: S) and identity‑security specialist Silverfort announced a strategic partnership on April 21 2026 to secure human, AI agent, and other non‑human identities (NHIs). The alliance combines Silverfort’s runtime security for identities with SentinelOne’s Singularity Platform, which protects endpoints, cloud workloads and AI applications, creating a unified control plane for autonomous runtime protection across the enterprise.
The partnership addresses the growing need to protect AI‑driven workloads and autonomous agents. By unifying identity, endpoint, and cloud security, SentinelOne expands its footprint in the identity‑security market and complements its AI‑native security capabilities, positioning the company to defend against sophisticated identity attacks that target both people and machine identities.
"By joining forces with Silverfort, we're moving beyond traditional boundaries to create a security ecosystem that is truly autonomous. We want to take the guesswork out of identity protection. Together, we're delivering a level of visibility and real‑time enforcement that neither identity nor endpoint tools could achieve alone, ensuring our customers remain resilient in an increasingly complex threat landscape," said Melissa K. Smith, SVP of Global Strategic Partnerships and Initiatives at SentinelOne. "Security architectures built around isolated tools are failing to keep up with modern threats. By unifying runtime identity enforcement with autonomous AI security, we are helping organisations stop identity‑driven attacks before damage occurs and preparing them to secure the next generation of AI‑powered environments," added Ron Rasin, Chief Strategy Officer at Silverfort. "Together, this joint solution enables organisations to secure their entire environment from a single platform, consistently across both cloud and on‑premises environments," he added.
SentinelOne reported Q4 FY2026 revenue of $1 billion, a 22% year‑over‑year increase, and achieved full‑year operating profitability. The company’s Q4 EPS of $0.07 beat analyst estimates of $0.06, while revenue of $271.15 million fell slightly short of the $271.18 million consensus. Gross margins have declined for five consecutive quarters, and insider selling totaled $4.6 million in the three months leading up to the announcement. SentinelOne’s AI security portfolio expanded in March 2026 with the launch of Prompt AI Agent Security, Prompt AI Red Teaming, and the general availability of Purple AI Auto Investigation.
The alliance positions SentinelOne to capture the rapidly growing AI security market. Silverfort’s patented Runtime Access Protection technology extends security to previously unprotected resources, while SentinelOne’s Singularity Platform delivers AI‑driven threat detection and response. Together, the partnership offers customers a single platform that protects people, devices, and AI agents in real time, potentially opening new revenue streams and deepening customer engagement in an era of increasing AI adoption.
