Shift Security is a cybersecurity company focused on third-party risk management (TPRM). The platform is designed to help organizations manage vendor-related security exposure through an agentic, AI-driven approach that replaces manual, compliance-driven workflows with continuous, automated processes. The platform covers the full vendor lifecycle, including discovery, onboarding, ongoing monitoring, re-assessments, offboarding, and breach response. Key capabilities include automatic vendor risk re-evaluation as posture or access changes, real-time monitoring of third-party access to identify risky or excessive permissions, and automated workflows for vendor lifecycle closure. The platform also provides AI-driven intake, tiering, evidence collection, artifact review, and gap analysis during vendor onboarding. A core feature is the platform's ability to operate inside the firewall, providing visibility into which vendors have access to internal systems and sensitive data. It surfaces shadow vendors and unauthorized access paths, and delivers tailored breach impact reports with automated containment actions when a vendor incident occurs. Shift Security targets enterprise security teams and CISOs seeking to reduce third-party exposure beyond traditional questionnaire-based compliance programs. The company claims up to 86% reduction in total third-party exposure, discovery of 5x more shadow vendors, and up to 93% reduction in manual onboarding work. Partners include Wiz, NVIDIA, Cyera, AWS, and Okta. The platform has received endorsements from former CISOs at Barclays and F5, as well as the co-founder of Aqua Security.
