The Cognitive Firewall:Securing Browser Based AI Agents Against Indirect Prompt Injection Via Hybrid Edge Cloud Defense

Researchers developed the Cognitive Firewall, a hybrid edge-cloud defense system that protects browser-based AI agents from indirect prompt injection attacks. The three-stage architecture reduces attack success rates to below 1% while maintaining 17,000x faster response times compared to cloud-only solutions by processing simple attacks locally and complex threats in the cloud.
