Machine Identity
Machine identity is the credential or certificate that uniquely identifies a non-human workload—such as a server, container, service, or AI agent—allowing it to authenticate to other systems.
Why this matters for AI agents
Machine identity proves that a system is who it claims to be. But authentication does not answer whether the authenticated system is authorized to perform the specific action it is attempting.
How AgntID relates
AgntID operates downstream of machine identity authentication—once a workload is authenticated, AgntID evaluates whether its agent should invoke a specific tool for a specific task.
The static IAM gap
Machine identity systems focus on authentication. They issue and rotate certificates but do not govern what an authenticated machine is allowed to do at the tool-call level.

Frequently asked questions
What is machine identity?
Machine identity is the credential or certificate that uniquely identifies a non-human workload—such as a server, container, service, or AI agent—allowing it to authenticate to other systems.
Why is machine identity insufficient for AI agent security?
Machine identity proves authentication. It does not answer whether the authenticated workload is authorized to perform the specific action it is attempting at that moment.
How does AgntID build on machine identity?
AgntID operates downstream of machine identity. Once a workload is authenticated, AgntID evaluates whether that workload's agent should invoke a specific tool for a specific task.
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.
