Managing non-human identities (NHIs) in cloud-native environments is increasingly complex as machine identities outnumber human ones. NHIs encompass machine credentials, tokens, and keys along with their associated permissions. Key challenges include volume and lifecycle management, behavior monitoring, and coordination gaps between security and R&D teams. Agentic AI addresses these challenges through real-time anomaly detection, predictive analysis, and automated decision-making. A holistic NHI management approach covering discovery, classification, threat detection, and context-aware security offers benefits including reduced breach risk, improved compliance, operational efficiency, and cost savings. Industry-specific applications span financial services fraud detection, healthcare patient data protection, and DevOps secrets automation.
