Agentic security is the overarching practice of securing autonomous AI agents and the systems they operate within. It overlaps with AI agent security but is broader, addressing risks that emerge when agents coordinate or operate collectively, while also managing lifecycle-level protections. This includes governing access, enforcing policies, and monitoring autonomous actions across the ecosystem.

Why it matters: Without agentic security, autonomous agents could be manipulated, leak sensitive data, or make unsafe decisions, creating cascading failures or systemic vulnerabilities across multi-agent environments.
