Building the Agent Control Layer

27 Companies 4 Categories

The OpenAI and Hugging Face incident showed that autonomous agents cannot be trusted to report or police their own behavior. As agents gain more authority, companies will need an independent control and evidence layer around them. This landscape focuses on new pure play companies building that layer rather than established security platforms expanding into agent security.
