Introducing the Generative Application Firewall (GAF)Joan Vendrell Farreny, Martí Jordà Roca, Miquel Cornudella Gaya et al.
This paper introduces the Generative Application Firewall (GAF), a new architectural layer for securing LLM applications. Existing defenses -- prompt filters, guardrails, and data-masking -- remain fragmented; GAF unifies them into a single enforcement point, much like a WAF coordinates defenses for web traffic, while also covering autonomous agents and their tool interactions.
