Shift Security is an agentic third-party risk management (TPRM) platform that automates and unifies the vendor security lifecycle. It replaces manual, fragmented TPRM workflows with autonomous AI agents that continuously discover vendors, monitor third-party access, assess risk, and respond to incidents. Key functional areas include: Discovery & Visibility: Continuously identifies all vendors and their access paths, including unmanaged or shadow vendors, providing a unified view across the organization. Agentic Onboarding: Automates vendor intake, tiering, evidence collection, security artifact review, and gap analysis using customizable AI workflows. Access Monitoring: Provides real-time monitoring of third-party access to internal systems and sensitive data, flagging risky, stale, or excessive permissions. Re-assessments: Automatically re-evaluates vendor risk as posture, access, or context changes, without requiring manual intervention. Offboarding: Automates workflows to eliminate dormant risks and finalize vendor lifecycle closure. Breach Response: Delivers instant alerts on vendor breaches with tailored impact assessments and automated containment actions, with auditable response trails. The platform operates inside the firewall to provide deep visibility into vendor interactions. It targets enterprises seeking to reduce third-party exposure, with claimed outcomes including up to 86% reduction in total third-party exposure, 5x more shadow vendor discovery, and up to 93% reduction in manual onboarding work.
