SentinelOne Opens AI Agent Security Product to Early Access

SentinelOne’s Singularity Agentic Detection and Response entered early access Oct. 21, adding a tool designed to discover AI agents, govern their activity, and detect or stop unintended or malicious actions.

SentinelOne co-founder and CEO Tomer Weingarten said AI security must extend to agents as well as the systems and models they use. “AI Security has to cover everything AI touches: the surfaces it runs on, the models behind it, and now the agents acting on its behalf,” Weingarten said.

SentinelOne’s September expansion of Wayfinder Frontier AI Services included capabilities for code-risk analysis, compromise assessment and malware analysis. Those tools were in private preview at the time.

SentinelOne generated $292 million in revenue in fiscal second-quarter 2027, up 21% year over year. Annualized recurring revenue (ARR) rose 22% to $1.218 billion. The quarter ended July 31, 2026.
