Overview
About Prefactor
Prefactor is the essential control plane for AI agents, a foundational infrastructure you must have to move autonomous agents from proof-of-concept to secure, compliant production. It solves the critical governance gap that prevents regulated enterprises from deploying AI agents with confidence. For product, engineering, security, and compliance teams in industries like banking, healthcare, and mining, managing multiple agent pilots without Prefactor is an unacceptable risk. It provides a single, unified layer of trust that gives every AI agent a first-class, auditable identity. Prefactor transforms the complex, fragmented challenge of agent authentication, authorization, and auditing into an elegant, scalable solution. By offering dynamic client registration, delegated access, and fine-grained role-based controls, it ensures complete visibility and policy-as-code management over every agent action. Built with SOC 2-ready security and interoperable OAuth/OIDC support, Prefactor is not a luxury; it's the necessity that allows you to maintain regulatory compliance and prevent costly security incidents before they happen. It aligns all stakeholders around one source of truth, enabling you to govern faster with shared visibility, auditability, and control.
