Non-human identity management market projected to reach $25 billion by 2035

The global non-human identity (NHI) management market is projected to grow from $3.5 billion in 2025 to $25 billion by 2035, according to research from Astute Analytica. This represents a compound annual growth rate (CAGR) of 21.7% between 2026 and 2035.

Growth is being driven by the proliferation of AI agents, cloud services, APIs, and IoT devices. As enterprises transition AI from experimentation to full operational use, the need to manage the authentication, access permissions, and credentials of autonomous AI agents and automated systems has become critical.

Security risks such as leaked API keys, excessive permissions, and unmanaged service accounts are fueling demand for specialized solutions. These tools focus on detecting, authenticating, and monitoring non-human identities through zero-trust security frameworks and automated lifecycle management.
