Agentic AI Security & Responsible Deployment Guide

Agentic AI is not "just another chatbot." Agents can plan multi-step workflows, call tools and APIs, persist and evolve memory, coordinate with other agents, and take real-world actions with little or no human oversight.

That autonomy makes agents powerful—and also creates an entirely new attack surface. You must treat an agent as a non-human identity (NHI) operating with real credentials inside your environment.

This guide consolidates best practices into a single, opinionated reference for engineering and security teams. It aims to be:

  • Provider-neutral (fits OpenAI, Anthropic, local models, etc.)
  • Pattern-driven (concrete architectural patterns you can reuse)
  • Security-first (Zero Trust for agents: treat model + memory + tools as untrusted)
  • Aligned with established frameworks (NIST AI RMF, OWASP LLM Top 10, standard SDLs)
