+# NeuralTrust TrustGuard
+
+Native LiteLLM guardrail. Sends chat input and output to TrustGuard `POST /v1/evaluate`.
+
+## Config
+
+```yaml
+guardrails:
+ - guardrail_name: neuraltrust-trustguard
+ litellm_params:
+ guardrail: neuraltrust
+ mode: [pre_call, post_call]
+ api_key: os.environ/TRUSTGUARD_API_KEY
+ api_base: os.environ/TRUSTGUARD_API_BASE # default https://trustguard.neuraltrust.ai
+ collector_key: os.environ/TRUSTGUARD_COLLECTOR_KEY # tgcol_… ; optional if the API key is bound
+ unreachable_fallback: fail_closed
+ timeout: 5
+ default_on: true
+```
+
+## Auth
+
+Bearer `tgk_…` API key. Address the collector with `collector_key`, or omit it when the key is already bound to one.
+
+## Verdicts
+
+| TrustGuard `status` | LiteLLM |
+| --- | --- |
+| `block` | HTTP 400 (trace_id / request_id only; findings are not echoed) |
+| `transform` | rewrite the last user message / last text from `transformed_payload` |
+| `report` / `allow` | pass through (`report` is logged by trace_id) |
+
+Unknown verdicts, malformed bodies, and `transform` without a usable payload fail closed.
+
+## Fail-open vs fail-closed
+
+`unreachable_fallback` applies only to transport failures: connect errors, timeouts, HTTP 502/504.
+
+HTTP 503 entitlements, 401/403, other 4xx/5xx, and unusable TrustGuard verdicts always fail closed.
+
+`fail_open` means the request bypasses TrustGuard entirely when the endpoint is unreachable. It is off by default.
+
+## Streaming
+
+LiteLLM streaming guardrails default to `block_only`. `block` still fires on streamed calls. `transform` rewrites are not applied to the streamed tokens; use non-streaming requests when DLP redaction must reach the client.
