Prompt DLP explained: redact vs block (Balanced vs Strict)

Prompt DLP (data loss prevention) means scanning AI prompts for sensitive data and either redacting or blocking it before the model provider receives it. Enterprises often do this with gateways. Individuals can start with a local browser extension like SafePrompt.

Redact vs block

  • Redact: replace secrets with placeholders ([API_KEY]) so the prompt still makes sense
  • Block: remove or stop sensitive content more aggressively

SafePrompt defaults to redact mode because most users still want AI help after cleaning the secret.

Balanced vs Strict in SafePrompt

Balanced (daily default)

  • Fewer false alarms
  • May skip some card-like numbers when invoice/payment context is present
  • Best for coding and writing

Strict

  • Stricter about payment-card-like numbers even with invoice-style words
  • Use when handling customer or payment discussions
