Overview

About Prefactor

Prefactor is the essential control plane for AI agents, designed to bridge the critical gap between experimental proof-of-concept and secure, compliant, and scalable production deployment. In an era where autonomous AI agents are rapidly evolving from demos to core operational components, organizations face immense challenges in governance, visibility, and security. Prefactor directly addresses this by providing every AI agent with a first-class, auditable identity, transforming how enterprises manage their automated workforce. It is built specifically for product, engineering, security, and compliance teams within regulated enterprises such as those in financial services, healthcare, and mining, who are running multiple agent pilots and need a unified source of truth. The platform's core value proposition lies in turning the complex, fragmented challenge of agent authentication and authorization into a single, elegant layer of trust. By offering dynamic client registration, fine-grained role-based access control, policy-as-code management, and full auditability, Prefactor enables companies to govern their AI agents at scale with confidence. This ensures that innovation can proceed without compromising on security or regulatory requirements, allowing teams to move from isolated pilots to governed production deployments efficiently.
