Description
Fact0 is designed to facilitate security reviews and provide runtime audit trails specifically for AI agents. It aims to help enterprises prove tool boundaries, data exfiltration protections, and human-in-the-loop policies to Chief Information Security Officers (CISOs). By utilizing Fact0, organizations can unblock enterprise deals that are often stalled due to security review processes, enabling them to pass these reviews in days rather than months.

The platform features a universal fact layer that includes tamper-evident audit trails and execution observability for AI agents. This allows organizations to track every tool execution, input parameters, and output results with origin attributes. The tamper-evident history ensures that logs have not been altered, verified by third-party auditors, providing a mathematical proof of integrity. Additionally, signed evidence packs are created with an Ed25519 digital wax seal, allowing auditors to mathematically verify reports.
Fact0 operates asynchronously, ensuring that applications continue running without delays, even during agent loops. The platform is built for enterprise needs, focusing on proving tool permissions, data exposure, and human intervention in AI operations. It is particularly beneficial for industries such as fintech, healthcare, and legal, where accountability and compliance are critical.
Users can start with a free tier that allows for 30,000 monthly audit events, making it accessible for teams looking to instrument their agents and pass initial security reviews. As organizations grow, they can scale to Pro or Enterprise plans that offer additional features such as collaborative tools, role-based access control, and self-hosting options. Fact0 is also completing its SOC 2 Type II audit, with security posture details available upon request.
