Credential Blast Radius
Credential blast radius is the total access that becomes compromised if a credential used by an AI agent is stolen, leaked, or misused—determined by the scope and lifetime of that credential.
Why this matters for AI agents
In agent systems, a single compromised credential can expose many systems if that credential has broad scope and a long lifetime. Blast radius is the practical measure of credential risk.
How AgntID relates
AgntID minimizes credential blast radius by issuing scoped ephemeral credentials per task—a compromised credential has access only to the specific task scope for which it was issued.
The static IAM gap
Service account keys and broad OAuth tokens have enormous blast radius. IAM does not provide a mechanism for reducing blast radius at the per-call or per-task level.

Frequently asked questions
What is credential blast radius?
Credential blast radius is the total access that becomes compromised if a credential used by an AI agent is stolen, leaked, or misused—determined by the scope and lifetime of that credential.
Why do agents have high credential blast radius by default?
Agents typically run under service accounts or OAuth tokens with broad permissions and long lifetimes. A single leaked credential can expose many systems.
How does AgntID minimize credential blast radius?
AgntID minimizes credential blast radius by issuing scoped ephemeral credentials per task. A compromised credential has access only to the specific task scope for which it was issued.
Secure every agent tool call at execution time.
AgntID gives infrastructure teams scoped, ephemeral access control for AI agents without replacing IAM, MCP servers, tools, or agent frameworks.
