As enterprises adopt cloud, automation, and AI, digital identity has shifted beyond humans. Non-human identities (NHIs) such as service accounts, devices, and AI agents outnumber human users and operate at machine speed, creating new security, operational, and compliance challenges. The growth in AI agents is especially concerning to security professionals. These NHIs are ephemeral, high-privileged, fast-moving, and invisible to legacy IAM. They constitute a huge risk if left unmanaged.
