Silverfort , the identity security company, and SentinelOne® (NYSE: S), a leader in AI security, today announced a strategic partnership to secure human identities, AI agents and other non-human identities (NHI). This collaboration brings together best-in-class runtime security across identities, endpoints, cloud workloads and AI applications to protect against increasingly sophisticated identity attacks. As a result, organizations can confidently leverage agentic innovation while ensuring they have autonomous defenses in place to detect and respond to both human and agentic threats at machine speed.
As enterprises accelerate the adoption of AI-powered systems and agent-based platforms, new forms of identity risk are also emerging. Modern enterprise environments are now populated by a diverse set of “workers,” including service accounts, APIs, workload identities, and increasingly autonomous AI agents. These agents perform actions for people and systems at machine speed and scale. In recent weeks, high-profile attacks have provided a preview of what lies ahead for modern defenders and the speed with which they will need to respond to agent-based and identity-based threats in today’s automated enterprise.
On March 31, 2026, a North Korean state actor carried out a sophisticated supply chain attack by hijacking the npm credentials of the primary Axios developer. In this attack the first infection was observed 89 seconds after publication, a rate that no manual workflow could defend.
One week earlier SentinelOne detected and blocked a trojanized version of LiteLLM which had been updated by an autonomous coding assistant – which identified and preemptively shut down a malicious process chain originating from Anthropic’s Claude Code running with unrestricted privileges. The malicious action was performed without any human in the loop. Just a normal, automated workflow. In this case, SentinelOne’s behavioral AI detected the trojanized package in mid-execution and preemptively shut it down in under 44 seconds.
While these are examples of attacks from third-party software supply chains, they all illustrate how quickly such trusted authentication tactics can be carried out in modern, automated IT environments, and how quickly security teams need to respond.
Through this partnership, Silverfort and SentinelOne address this challenge head-on by securing identity at runtime, resulting in faster containment, reduced lateral movement, and privilege escalation. Silverfort’s expertise in detecting and securing AI agents, non-human identities, combined with SentinelOne’s leadership in AI-driven detection and its expansion into AI security, lays a foundation for securing environments where humans, machines, and AI agents work simultaneously and autonomously. The impact for customers is immediate and significant. Identity risk becomes a first-class signal in AI-driven threat detection and automated SOC workflows, and illicit authentication requests are stopped at runtime while compromised credentials can be isolated and quarantined.
The partnership goes beyond simple integrations to deep technical collaboration and joint research, integrating identity verification directly into autonomous security operations. By carefully aligning Silverfort's runtime Identity Security With SentinelOne's AI-powered Singularity™ security, enterprises establish a unified, real-time control plane to connect identity and endpoint information into a single decision tree, enabling real-time enforcement actions across both endpoint and identity domains.
”Security architectures built around isolated tools are unable to keep up with modern threats,” says Ron Rasin, Chief Strategy Officer, Silverfort. ”By unifying identity management at runtime with autonomous AI security, we help organizations stop identity-driven attacks before damage occurs and prepare them to secure next-generation AI-driven environments. Together, this joint solution enables organizations to secure their entire environment from a single platform, consistently across both cloud and on-premises environments.”
Key aspects of the joint solution and partnership include:
- Runtime identity security: Silverfort Discovers protects all identity types with runtime access controls, including multi-factor authentication (MFA), just-in-time (JIT) access, virtual machine identity demarcation, and customizable policies. IT extends robust identity security controls to sensitive resources and assets, including legacy systems, proprietary applications, and critical IT infrastructure that was previously unprotected.
- AI-powered threat detection and response: SentinelOne's Singularity platform delivers best-in-class, AI-powered detection and response capabilities across endpoints, cloud workloads, and user identities. The joint solution enables real-time correlation of endpoint and identity signals during execution. This enables seamless data exchange to enrich threat context and accelerate remediation actions.
- Autonomous safety position: The integrated solution enables organizations to autonomously block identity-based threats at runtime, preventing attackers from using legitimate credentials to move laterally within the network. This significantly reduces the window of exposure and impact of a potential breach. Responders can surgically remove threat actors without taking down the entire business.
- Simplified deployment and management: Joint customers benefit from a simplified security architecture that centralizes identity security management, improves operational efficiency, and provides a coherent security posture across the entire IT ecosystem.
”"In cybersecurity, the strongest defense is a unified defense,", says Melissa K. Smith, SVP of Global Strategic Partnerships & Initiatives, SentinelOne. ”By joining forces with Silverfort, we are moving beyond traditional boundaries to create a security ecosystem that is truly autonomous. We want to eliminate the guesswork when it comes to identity protection. Together, we deliver a level of visibility and real-time enforcement that neither identity nor endpoint tools could achieve on their own, ensuring our customers remain resilient in an increasingly complex threat landscape.”
