Agent Blast Radius: Measuring AI Failure Impact
Definition
The blast radius of an AI agent failure is the total scope of damage — data loss, financial impact, reputational harm, compliance violations, and operational disruption — that results from a single unauthorized, hallucinated, or malicious agent action. The blast radius is determined by the agent's access scope (what it can reach), the irreversibility of the action (can it be undone), and the detection latency (how long before the failure is noticed).
Why It Matters
Without execution governance, the blast radius of an over-permissioned agent is functionally unlimited. An agent with full database write access can delete every record. An agent with billing API access can issue unlimited refunds. An agent with email API access can send unauthorized communications to every customer. The blast radius grows exponentially with the agent's permission scope and the time between the failure and its detection. In multi-agent systems, cascading failures can amplify a single agent's blast radius across an entire infrastructure.
How Exogram Addresses This
Exogram reduces agent blast radius to zero by enforcing least-privilege governance at the action level. Even if an agent has broad credentials, every individual action is validated against deterministic policy rules before execution. Destructive actions are blocked. Scope violations are rejected. The blast radius of any individual agent failure is contained to the single action that triggered the policy violation — and that action never executes.
