Agentic AI Security: The Risks Every Business Must Know | Erich Kron (KnowBe4)

AI agents don't just answer questions; they take action. And when an AI agent gets bad information, a wrong answer can quickly become a security incident.

In this 403 Circle webinar powered by Astra Security, Erich Kron (CISO Advisor at KnowBe4, 30 years in cybersecurity, former Security Manager of the U.S. Army's Second Regional Cyber Center) breaks down why agentic AI is going to change the way we do business and what security leaders need to do before handing autonomous AI agents the keys.

🔍 What you'll learn:

  • AI agents vs LLMs: the difference between "answering" and "doing"
  • Agentic AI vs generative AI: and why agents rely on LLMs under the hood
  • How LLMs actually work (tokens and probability) and why AI hallucinates
  • Why a hallucination inside an AI agent can become a real incident at machine speed
  • How attackers social-engineer AI agents with hidden prompt injection
  • Real-world cases of AI agents going rogue, and the lessons behind them
  • Why AI agents should be treated as non-human insider threats
  • Levels of autonomy: observe → recommend → act with approval → autonomous
  • Practical guardrails: least privilege, non-human identities (NHIs), human in the loop, monitoring, and rollback
