Human vs. Non-Human Identity in SaaS

Non-human SaaS identities (OAuth apps, service accounts, API keys and other integrations) are frequently overlooked, granted broad or shared permissions, and exhibit non‑human usage patterns that make them attractive targets for threat actors. The article recommends treating non-human accounts with the same visibility and governance as human users by unifying them in the user inventory, applying least-privilege permissions, prohibiting shared high‑permission API keys, restricting access via IP allowlists and non‑UI authentication, and deploying SaaS Security Posture Management (SSPM) alongside Identity Threat Detection & Response (ITDR) to detect anomalous behavior and reduce risk.
