Use cases

What Stardust protects against

ChatGPT & Claude

Intercept outgoing messages before they reach any AI model — block or alert on PII, credentials, and confidential content in real time.

File Upload Scanning

Every DOCX, XLSX, PPTX, PDF and text file uploaded to an AI tool is extracted and scanned against your DLP rules before it leaves the browser.

Credential Protection

AWS keys, API tokens, passwords, and secrets are caught by pattern matching before employees accidentally paste them into an AI prompt.

PII & Regulated Data

Social security numbers, credit card numbers, phone numbers, and email addresses are flagged automatically without any custom configuration.

Department Policies

Finance, Legal, and Engineering can each have stricter or looser rulesets. Policies are scoped per department and applied automatically.

Compliance Audit Trail

Every message and file that triggered a rule is logged with the user, platform, timestamp, and matched rule — ready for your next audit.

How it works

Up and running in minutes

01

Install the extension

One-click install from your admin panel. The extension is privately distributed — only your org gets it.

Configure your policies

10 standard DLP rules are seeded automatically. Add custom patterns, keywords, and per-department rules in minutes.

03

Protect in real time

Every prompt and file upload across ChatGPT, Claude, and Gemini is scanned. Violations are blocked or logged instantly.

Features

Everything you need to secure AI

Real-time interception

Patches fetch and XHR at the browser level — zero latency, zero bypass.

Office doc parsing

Extracts text from Word, Excel, PowerPoint and plain text files via JSZip.

Block or alert

Per-rule severity — block silently cancels the upload; alert logs and continues.

Auto-classification

Detects Confidential, Restricted, Internal and other markers in file content.

10 default policies

Every org starts with SSN, card numbers, AWS keys, PII patterns and more.

Admin analytics

See top uploaders, file types, classification breakdown and alert trends.
