Request Reject Flag

The request_reject flag is a boolean field in the guardrail response that indicates whether the evaluated content should be rejected based on security policy violations.

• Inspect Policy: When application policy is set to "inspect", request_reject will be false even if threats are detected

• Reject Policy: When application policy is set to "reject", request_reject will be true when threats exceed thresholds
