When exploring the use of Large Language Models (LLMs) in application security, a new frontier emerges for Web Application Firewalls (WAFs). Traditionally, WAFs operate on structured rules to detect and block application attacks, but what if we could leverage the unique capabilities of an LLM? In this talk, we will delve into the potential of using LLMs as WAFs, evaluating their strengths, challenges, and implications.

During this talk attendees will learn how existing applications may need to evolve to align with LLM capabilities, as well as discussing how LLMs can not only help detect threats and reduce false positives but also adapt better to zero-day vulnerabilities.

Through live demonstrations and a practical breakdown of potential architectures, this talk will equip attendees with actionable insights into how LLMs can transform application security while addressing the challenges they bring to the table.
