About Impart Security | Runtime AI Security Platform

At AI Speed, Runtime Is the Only Source of Truth

Most security tools were built to run outside of where the action is. They sit outside production systems, monitoring and alerting rather than taking action. In the AI era, that approach is no longer effective.

Impart was built to be a runtime security control that changes outcomes by being running where the action is - within runtime. Running within the runtime is the only way security teams can stop attacks, control agents, and shape outcomes with the accuracy and precision needed for the AI era.
