Agentic AI can strengthen data security by automating decision-making, detecting anomalies in real time, and adapting to evolving threats. Central to this approach is the management of Non-Human Identities (NHIs) — machine identities composed of encrypted credentials and associated permissions. A holistic NHI management strategy covers discovery, classification, threat detection, and remediation, delivering benefits like reduced breach risk, improved compliance, increased efficiency, and cost savings. Agentic AI enhances these frameworks by providing predictive analytics and scalable, context-aware security, particularly in cloud environments. Practical applications span financial services, healthcare, and DevOps, where NHIs automate identity verification, enforce access controls, and secure delivery pipelines.
