Silverfort, an identity security company, and SentinelOne, an AI security leader, have announced a strategic partnership to deliver enhanced runtime security for human, AI agent, and other non-human identities, aiming to counter increasingly complex identity attacks.
The collaboration integrates runtime security capabilities across identities, endpoints, cloud workloads, and AI applications. This initiative is designed to enable organizations to leverage agentic innovation while deploying autonomous defenses capable of detecting and responding to both human and agentic threats at machine speed.
The increasing adoption of AI-driven systems and agentic platforms in enterprise environments has introduced new identity risks. Modern IT infrastructures now feature a diverse range of “workers,” including service accounts, APIs, workload identities, and autonomous AI agents that execute actions at high speeds. Recent incidents underscore the rapid response required from defenders against agentic and identity-based threats in automated enterprises.
As an example, on March 31, 2026, a North Korean state actor executed a supply chain attack by compromising the npm credentials of a primary Axios maintainer. The initial infection was observed 89 seconds after publication, indicating a pace beyond manual defense capabilities. Prior to this, SentinelOne detected and blocked a trojaned version of LiteLLM, updated by an autonomous coding assistant, identifying and neutralizing a malicious process chain originating from Anthropic’s Claude Code that operated with unrestricted permissions. This action, completed in under 44 seconds, was an automated workflow without human intervention. These cases highlight the speed with which trusted authentication tactics can be exploited in automated IT environments.
Through their partnership, Silverfort and SentinelOne aim to address these challenges by securing identity at runtime, leading to faster threat containment and reduced lateral movement and privilege escalation. Silverfort contributes its expertise in discovering and securing AI Agents and non-human identities, while SentinelOne brings its AI-powered detection capabilities and expanding focus on AI security. This collaboration establishes a foundation for securing environments where human, machine, and AI agents operate concurrently and autonomously.
For customers, this partnership integrates identity risk as a primary signal within AI-driven threat detection and automated Security Operations Center (SOC) workflows. Illegitimate authentication requests are intended to be halted at runtime, and compromised credentials can be isolated and quarantined. The partnership involves deep technical collaboration and joint research, embedding identity enforcement directly into autonomous security operations. By aligning Silverfort’s runtime Identity Security with SentinelOne’s AI-powered Singularity™ security, the companies are developing a unified, real-time control plane to consolidate identity and endpoint intelligence, enabling real-time enforcement actions across both domains.
Ron Rasin, Chief Strategy Officer at Silverfort, stated that security architectures built on isolated tools struggle with modern threats. He added that unifying runtime identity enforcement with autonomous AI security helps organizations stop identity-driven attacks and prepares them for AI-powered environments, providing a single platform for security across cloud and on-premises environments. Melissa K. Smith, SVP of Global Strategic Partnerships & Initiatives at SentinelOne, commented on the strength of unified defense, stating that the partnership moves beyond traditional boundaries to create a truly autonomous security ecosystem, offering visibility and real-time enforcement capabilities beyond what individual identity or endpoint tools can achieve.
Key aspects of the joint solution include:
Runtime Identity Security: Silverfort’s platform discovers and protects all identity types, implementing runtime access controls such as Multi-Factor Authentication (MFA), Just-in-Time (JIT) access, virtual fencing for machine identities, and adaptive policies. It extends robust identity security controls to sensitive resources, including legacy systems, proprietary applications, and critical IT infrastructure that may have been previously unprotected.
AI-Powered Threat Detection and Response: SentinelOne’s Singularity Platform offers AI-driven detection and response across endpoints, cloud workloads, and user identities. The joint solution enables correlation of endpoint and identity signals during real-time execution, enriching threat context and accelerating remediation.
Autonomous Security Posture: The integrated solution is designed to autonomously block identity-based threats at runtime, preventing attackers from using legitimate credentials for lateral movement within a network. This approach aims to reduce the window of exposure and the potential impact of a breach, allowing incident responders to address threats precisely.
Simplified Deployment and Management: Joint customers are expected to benefit from a streamlined security architecture that centralizes identity security enforcement, enhancing operational efficiency and fostering a cohesive security posture across the entire IT ecosystem.
