Senthex

Senthex is a transparent reverse proxy that scans every API call to OpenAI, Anthropic, Mistral, Gemini, and OpenRouter in real time. You change one line of code (your base_url) and get 24 security shields: prompt injection detection with multi-turn tracking, PII redaction, secrets scanning, automatic prompt hardening, data classification with provider routing, budget circuit breaker per agent, canary tokens for system prompt leak detection, and response toxicity scoring. Agent-native every response includes metadata headers so autonomous agents can self-monitor. Anti-bypass system with progressive trust levels. 600+ tests, 16ms overhead, Python SDK on PyPI. Free beta.
