Status unknown Integrate Run a live scan

Pre-action security for agent systems

A security boundary for agent actions.

Warden inspects untrusted agent output before it reaches payments, tools, links, or secrets. It returns a policy verdict and an inspectable record.

Request path

              
Place Warden before execution.

            

            

              The caller sends output and context to Warden, receives a
              decision, then applies its own policy before any consequential
              action.

              SANITIZE

              BLOCK

            Fast checks cover known patterns. Optional semantic analysis covers
            novel phrasing only when thorough mode is enabled. Evaluation
            figures are dated snapshots, and ALLOW is not a universal safety
            guarantee.

                The bundled reference record is verified locally. One byte is
                then changed and the same verifier must reject the chain.
