Harden

Harden is building the security layer for the new generation of AI agents. As agents gain access to code, infrastructure, APIs, business data and production systems, companies need a way to control what those agents can actually do. Harden sits at the action boundary. Before an AI agent executes a shell command, calls an API, moves sensitive data, changes infrastructure or invokes a tool, Harden evaluates the action and enforces the right policy. Our platform combines build-time security with runtime enforcement. Teams can scan agentic applications for risks across code, dependencies, secrets, configurations and deployment posture, then apply controls at runtime across tool usage, API access, network destinations, sensitive data movement and permissions. Harden is designed to work across different AI coding agents and agent frameworks rather than locking security to a single model or vendor. The goal is simple: let agents build and operate quickly while keeping security teams in control of what they are allowed to do.
