The company extends Zero Trust security to the actions AI agents take. Instead of keeping credentials, keys, and secrets in one place, Outerlimit splits them across the agent system. They are only brought together when an agent needs to use a tool.

Before any action is executed, the system checks the agent’s identity, permissions and context. This ensures every action is authorised and gives businesses control over exactly what an AI agent can do.

"The demand to deploy agentic AI is unparalleled, but security teams are being asked to sign off on risks they cannot adequately control," said Tony Pepper, CEO of Outerlimit. "Blocking adoption isn't a strategy, it simply drives the use of unsanctioned AI outside of enterprise oversight.

"We've spent decades building security systems around human qualities such as loyalty, trust, compassion, and even fear which drive predictable decision-making," said Dr Peter Vincent, Founder and CTO of Outerlimit. "In this new agentic era, where agents use reasoning models with access to tools that can impact the world, they simply don't operate within these human constructs.
