Overview

Protect sensitive data from being sent to AI tools. Local-first detection of API keys, passwords, PII, and secrets.

VeriSentra – Prompt Firewall helps prevent accidental data leaks when using AI tools and web apps. VeriSentra scans text locally in your browser before you paste or send it, and can block, warn, or sanitize sensitive content like API keys, passwords, and PII—so secrets don’t end up in ChatGPT, Gmail, Slack, Notion, and more. What it does ? Detects sensitive data locally (no content uploaded) Blocks or warns before risky text is sent Sanitizes text by replacing secrets with safe placeholders Works on popular AI + SaaS apps Team policies (optional): admins can manage rules for the whole workspace Detects common risks API keys and tokens (AWS, GitHub, OpenAI, Stripe, etc.) Passwords and credentials Private keys (SSH / RSA / PGP) Personal data (emails, phone numbers, addresses, ID numbers) Financial data (credit card patterns) Local-first privacy Your text stays on your device. We do not store or transmit message content. Optional telemetry is counts only (blocked/warned/sanitized), never the text itself.
