Show HN: ReasonGate- An explainable gate that blocks LLM prompt injection
Summary
ReasonGate is an explainable security gate for LLM applications designed to block prompt injection. It combines a multi-layer defense (normalization, injection/jailbreak detection, indirect-injection scanning, multi-turn shielding, and output leakage detection) with an auditable decision trail, and offers an open-core, rule-based base plus an enterprise ML-enabled add-on. The project emphasizes transparency, deployability (including air-gapped operation), and demonstrable defense through live demos and benchmark results.
