Arc Sentry blocks LLM prompt injections pre-generation

Arc Sentry represents a shift from reactive text-based filtering to proactive architectural monitoring for LLM security. By hooking into the residual stream, it catches adversarial steering that bypasses traditional guardrails.

• –Operates at the model's internal layer level, making it resistant to "noise" that confuses text-based classifiers.
• –Pre-generation blocking ensures harmful tokens are never even computed, let alone leaked.
• –Specifically optimized for Mistral, Qwen, and Llama architectures popular in local deployments.
• –Effective against "Crescendo" multi-turn attacks that typically fly under the radar of single-turn filters.
• –Strategic $199/mo pricing for production use, with a free audit offer to lower the barrier for developers.
