Your WAF Can’t Read: Prompt Injection and the Limits of Pattern-Matching Security
Attention to all DevOps, Security, FinTech, and GenAI enthusiasts!
Planview Vancouver Platform Engineering Team (FlowPlatform Team) is hosting a meetup at their office, bringing together techies across the city for a deep dive into securing AI agents on December 4th from 2:00 - 4:30 PM!
Your WAF can block SQL injection in its sleep, but it can't read a prompt. A prompt injection is perfectly normal natural language, so there is no signature to match. Now that AI agents call APIs, run tools, and act with valid credentials, the traffic looks legitimate even when the agent has been tricked into doing the attack.
This session explores why traditional security tooling struggles with agentic systems, what your WAF and delivery layer can and can't see, and how to build a layered defence with gateways, guardrails, least-privilege access, and human approval where it matters.
Speakers:
Scott McAllister, Community Evangelist, F5 & (Developer Advocate & Educator)
Adetokunbo Ige, Senior Software Engineer (Platform Engineer), Planview & (CNCF Ambassador, AWS Community Builder, Ambassador Community Advocate - Ambassador Labs)
