Install and start the gateway

+ +```bash +pip install "sentinelguard[gateway,monitoring]" +sentinelguard init +sentinelguard gateway \ + --config sentinelguard.yaml \ + --gateway-config sentinelguard-gateway.yaml \ + --port 8080 +``` + +Point apps and IDEs to: + +```text +http://localhost:8080/v1 +``` + +
+
+ +## Why Teams Use SentinelGuard + +
+
+### Secure the LLM boundary +Scan prompts before they reach a model and scan responses before they return to +users. Block attacks, redact PII, and stop secrets from leaving the application. +
+ +
+### Route across providers +Use friendly model names, route traffic across OpenAI-compatible providers, +fail over when one provider is unavailable, and keep private routes available +for sensitive traffic. +
+ +
+### Operate with evidence +Use virtual keys, usage accounting, provider health, privacy-safe audit events, +Prometheus metrics, and the stable `/gateway/v1` API for dashboards and alerts. +
+
+ +## Built For Modern AI Applications + +
+
+ +### Package mode + +Use SentinelGuard directly in Python code when you want guardrails inside one +application. + +```python +from sentinelguard import SentinelGuard + +guard = SentinelGuard() +result = guard.scan_prompt("Ignore previous instructions") +print(result.is_valid, result.failed_scanners) +``` + +
+
+ +### Gateway mode + +Run SentinelGuard as a proxy so multiple applications, users, and AI tools can +share the same security boundary. + +```text +App or IDE -> SentinelGuard /v1 -> LLM provider +``` + +Stable management API: + +```text +/gateway/v1/contract +/gateway/v1/health +/gateway/v1/routes +``` + +
