Why Securing AI Agents Requires a New Approach

AI agents do not behave like traditional software. Securing them means moving beyond access and protocols to govern autonomous systems in real time.

What makes AI agents different?

AI agents are like digital employees, with roles, access, data, and the ability to make decisions in pursuit of goals in real time. The minimum viable definition of an agent is a large language model equipped with at least one tool. The tool can be anything from an API to an MCP to a SaaS connector.

  • Agents are different in both focus and scale to how human employees operate:

    Agents can chain tools, make instant decisions, and have the capability to impact operations at a speed and call orders-of-magnitude beyond any employee or team.

  • Agents function differently than traditional software:

    Agents are unpredictable, and their decisions do not follow a specific logic chain, meaning the requirements for controls, behavioral observability, and contextual governance are critical.

  • Agents are non-deterministic:

    Even if you test agents pre-deployment, the risks and behaviors won't remain the same. Know which agents are in use, by which teams, and for what work, so you can guide adoption and governance.

What Purpose-Built Security for Your Agents Actually Looks Like

Geordie gathers data directly from where your agents operate: across code, cloud, and endpoint, and across the architectures and tool connections in your environment. That coverage gives your team a continuous view of agent behaviour and risk that static policies and access controls can't provide.

A complete and continuously updated picture of your agent environment

Most organisations don't have an accurate view of which agents are running, what they're connected to, or how their configurations change over time. Geordie automatically discovers every agent across your cloud, code, and endpoint environments and maintains a continuously updated map of their full configuration.

Understanding what your agents actually do, not just what they're permitted to do

Permissions define what an agent can do. Behaviour tells you what it does. Geordie maintains an auditable record of every decision, tool call, and data access across your agent fleet. Behavioural baselining and anomaly detection identify when something falls outside expected bounds.

Risk intelligence that reflects how agents actually create risk

Agent risk emerges from sequences of actions, context, and downstream consequences, not individual transactions. Geordie analyses activity and configuration using proprietary risk and threat modelling, with findings mapped to relevant standards.

Controls that work at the speed of your agents

Agents deliver value by operating continuously and autonomously. Geordie evaluates each decision in context, applying controls directly at the agent level so operations continue uninterrupted.

Existing Approaches Weren't Designed for How Agents Operate

Endpoint and network security

Endpoint and network security was built around human-initiated activity. When agents operate machine-to-machine, that traffic can bypass traditional choke points entirely, or arrive without the context needed to evaluate it. You can see that something happened, not what it means.

What you can do with agents you trust

When your agents are understood, approved with evidence, and operating under controls that work at their level, your organisation can deploy faster, expand further, and build on what's working. That's what Geordie makes possible.

“We're seeing the iceberg that rocked the Titanic — weeks in advance rather than the moment it appears on screen. We're able to take a snapshot of the entire ecosystem and have adult, grown-up conversations about what's responsible and what's not. We can quantify everything now.”
