This talk addresses the escalating sophistication of AI attacks, moving beyond simple prompt injection to complex exploits targeting LLM interfaces, data, and even internal mechanisms. It proposes a practical, low-latency, self-hosted defensive layer built by fine-tuning a modern encoder model, specifically ModernBERT, to act as a guardrail against these threats. The approach emphasizes efficiency and cost-effectiveness, aiming for a defense under a dollar per instance.
