Agentic AI systems are replacing traditional RAG implementations after 72-80% of enterprise RAG deployments failed in 2025. While agentic architectures like self-RAG and CRAG solve reliability problems, they introduce severe security risks including indirect prompt injection, memory poisoning, and agentic denial-of-service attacks. Real exploits like EchoLeak demonstrate how agents with tool access can be manipulated to exfiltrate data or execute unauthorized actions. Defense strategies now require unified safety frameworks with guardian agents, architectural diversity to prevent systemic vulnerabilities, and regulatory compliance with updated NIST AI Risk Management Framework guidelines.

Why 2025’s agentic AI boom is a CISO’s worst nightmare
