How to prevent secrets and sensitive data from leaking into AI prompts.
Prompt security controls inspect requests before model execution. The goal is to stop credentials and high-risk sensitive data from leaving internal systems.
Posturio AI Gateway applies prompt policies that can block, redact, or reroute risky requests while keeping a complete decision trail.
Prompt security workflow
Block credentials before they reach model providers
Token patterns such as cloud keys and API credentials should be blocked at the gateway. This is one of the highest-impact controls for reducing leakage from internal AI usage.
Route high-risk prompts to controlled environments
Sensitive prompts can be routed to approved internal models or restricted provider paths. Routing policy keeps sensitive workflows aligned with security requirements.
Keep prompt security decisions observable
Policy outcomes, routing decisions, and blocked events should be captured as structured metadata so security teams can verify controls and investigate anomalous behavior.
