VeriSentra – Prompt Firewall

About

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.

How it works

Install the extension
Open a supported site (AI tools, email, chat, docs)
When you paste or send text, VeriSentra checks it locally
If something sensitive is found, you can block, edit, or sanitize
