Machine Identity

Machine identity is the verifiable identity of a non-human actor such as a service, bot, AI agent, build job, server, container, or API client. In an AI stack, software components often call models, write files, open tickets, trigger deployments, and access internal systems without a person pressing every button. Each of those actors needs an identity that can be assigned permissions, monitored, and revoked. A static API key is a weak substitute because it usually proves only that someone has the secret. A stronger machine identity ties access to a specific workload, runtime, device, certificate, or short-lived credential. That makes it possible to answer practical security questions: which agent performed this action, was it running in the expected environment, and did the permission match its role? For AI systems, machine identity is a control layer that keeps automation from becoming anonymous power inside the company network. This becomes critical when multiple agents can reach the same internal systems through different automation paths.
