Key questions answered by the NHI Mgmt Group independent editorial team.
Why are Non-Human Identities and AI Agents the #1 identity security threat?
Non-Human Identities and autonomous AI Agents have become the #1 identity threat in modern enterprises — both operate without human oversight, authenticate via credentials, and are rarely monitored. Per NHI Mgmt Group research, over 50 million leaked API keys, service accounts, and tokens were found on the dark web in 2024 — a 250% increase since 2021. AI Agents compound this by chaining access across multiple systems autonomously, widening the blast radius of any single compromised credential.
How many more Non-Human Identities are there than human identities?
Non-Human Identities now outnumber human identities by 50 to 100 times in modern enterprises. APIs, service accounts, bots, and machine identities control critical operations and enable seamless integrations, but their explosive growth has outpaced traditional security measures, leaving them highly vulnerable to exploitation.
Why is the Non-Human and Agentic AI Identity landscape expanding so rapidly?
The growth spans legacy on-premises systems, GenAI platforms, LLMs, MCP servers, agentic pipelines, API-based architectures, and hybrid cloud environments. Every new AI Agent deployment, automation workflow, or SaaS integration creates additional Non-Human Identities that require governance. This fragmented ecosystem makes security gaps harder to detect and requires advanced identity security strategies to ensure protection across increasingly diverse environments.
What security controls are typically missing for Non-Human Identities?
Many organisations fail to track or enforce NHI security policies, leaving machine identities without basic controls. Per industry research, 97% of NHIs carry excessive privileges, and weak controls enable unauthorised access, privilege escalation, and undetected lateral movement — making robust identity security crucial for protecting critical systems.
How do attackers target Non-Human Identities?
Service accounts, API keys, and machine identities now dominate digital environments, often with elevated privileges and minimal monitoring. Attackers target NHIs because this lack of oversight makes them high-value targets with low detection risk. NHIs have become the primary attack vector in cloud, automation, and API-driven enterprise environments.
What kind of breaches have been caused by compromised Non-Human Identities?
Attackers exploiting misconfigured APIs, stolen machine credentials, and overprivileged service accounts have caused significant breaches — gaining unauthorised access, moving laterally within networks, and exfiltrating sensitive data while evading traditional security detection. NHI Mgmt Group maintains the most comprehensive structured NHI breach database, analysing 52+ real-world NHI incidents.
What makes AI Agents a distinct identity security challenge?
AI Agents operate autonomously, authenticate via credentials, and can chain actions across multiple systems without human intervention. They are created far faster than traditional IAM processes can govern them, and their access patterns are often broader and more opaque than conventional service accounts. Without proper NHI governance frameworks applied to Agentic AI, organisations face significant blind spots in identity security posture.
How fast can an attacker compromise an unmanaged Non-Human Identity?
In many cases it takes less than one minute for a skilled attacker to compromise an unmanaged NHI and trigger a chain reaction leading to a much larger breach. The combination of always-on access, excessive privilege, and minimal monitoring makes NHIs the fastest path from initial access to enterprise-wide impact.
