The collaboration unifies security across identities, endpoints, cloud workloads and AI applications to protect against identity attacks.
Silverfort and SentinelOne have announced a partnership to secure human, AI agent and other non-human identities (NHIs). This collaboration unifies security across identities, endpoints, cloud workloads and AI applications to protect against sophisticated identity attacks.
As enterprises accelerate the adoption of AI-driven systems and agentic platforms, new forms of identity risk are also emerging. Modern enterprise environments are now populated by a diverse array of “workers,” including service accounts, APIs, workload identities, and increasingly autonomous AI agents. These agents are executing actions for humans and systems at machine speed and scale.
In the past few weeks, high profile attacks have provided a preview into what lies ahead for modern defenders and the speed at which they will need to respond to agentic and identity-based threats in today’s automated enterprises.
On March 31, 2026, a North Korean state actor executed a sophisticated supply chain attack by hijacking the npm credentials of the primary Axios maintainer. In this attack, the first infection was observed 89 seconds after publication, a pace no manual workflow could possibly defend.
A week prior, SentinelOne caught and blocked a trojaned version of LiteLLM that had been updated by an autonomous coding assistant – identifying and preemptively killing a malicious process chain originating from Anthropic’s Claude Code running with unrestricted permissions. The malicious action was done without any human in the loop. Just a normal, automated workflow. In this case, SentinelOne’s behavioral AI caught the trojaned package mid-execution, preemptively killing it in under 44 seconds, as detailed in the blog.
While these are examples of third-party software supply chain attacks, they each illustrate just how fast such trusted authentication tactics could be executed in modern, automated IT environments, and the speed at which security teams will need to respond.
Through this partnership, Silverfort and SentinelOne are directly addressing this challenge by securing identity at runtime, resulting in faster containment, reduced lateral movement & privilege escalation. Both the companies are laying a foundation for securing environments where humans, machines, and AI agents operate simultaneously and autonomously.
Identity risk becomes a first-class signal in AI-driven threat detection and automated SOC workflows and illegitimate authentication requests are stopped at runtime while compromised credentials can be isolated and quarantined.
Security architectures built around isolated tools are failing to keep up with modern threats,” said Ron Rasin, Chief Strategy Officer, Silverfort. “By unifying runtime identity enforcement with autonomous AI Security, we are helping organizations stop identity-driven attacks before damage occurs, and preparing them to secure the next generation of AI-powered environments. Together, this joint solution enables organizations to secure their entire environment from a single platform, consistently across both cloud and on-premises environments.”
“In cybersecurity, the strongest defense is a unified one,” said Melissa K. Smith, SVP of Global Strategic Partnerships & Initiatives, SentinelOne. “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.
