Prompt injection defenses often fail because they focus on detecting dangerous keywords rather than identifying untrusted content attempting to override instructions. Attackers can bypass simple filters through various encoding methods. A more effective approach involves assigning a trust level to different content sources, such as system prompts, user input, and external data, and enforcing rules that prevent lower-authority sources from issuing instructions. This method, implemented by ArcGate, aims to block or sandbox suspicious content before it reaches the language model, allowing for graceful degradation of capabilities when necessary. AI
