Test Your AI Security Right Now

Paste any prompt, code, or message your team sends to AI tools like ChatGPT, Claude, or Copilot. Our scanner instantly checks for 9 categories of sensitive data leaks — and tells you exactly how to fix them.

Generate your CMMC AI risk snapshot

Paste a real prompt your team sends to ChatGPT, Claude or Copilot. HoundShield's detection engines scan it locally, in your browser, map every finding to a NIST 800-171 control, and produce a preview gap-report PDF.

Your text is never sent anywhere — the scan and the PDF are generated entirely on this device.

What Our AI Scans For

HoundShield uses 13 AI models to detect 9 categories of sensitive data. Here's every threat pattern we check — and what makes our detection smarter than regex-only tools.

OpenAI API Keycritical

Rotate this key immediately in your OpenAI dashboard. Never hardcode API keys in source code — use environment variables…

AWS Access Keycritical

Deactivate and rotate this key in IAM immediately. Use IAM Roles instead of long-lived access keys wherever possible.

Social Security Number (SSN)critical

SSNs must never appear in AI prompts. Tokenize or mask them before processing. This is a HIPAA/PII violation.

Credit Card Numberhigh

Never send card numbers to external AI. Use payment tokens from Stripe/Braintree instead. This violates PCI-DSS.

Email Addressmedium

Emails are PII under GDPR. Anonymize them (e.g., j***@company.com) before including in AI prompts.

Password / Credential Leakcritical

Change this password immediately. Use a password manager and never include credentials in code or prompts.

Internal IP Addressmedium

Internal IPs reveal your network topology. Strip them from prompts to prevent reconnaissance attacks.

Private Keycritical

This private key is compromised. Revoke it and generate a new keypair immediately.

Database Connection Stringcritical

Rotate the DB password and restrict access. Use connection poolers and IAM auth instead of password strings.

How to Take the Test — Step by Step

1. Connect Your Company (Optional)

Enter your company name to tag scan results. This is purely for your reference — no data leaves your browser. If you skip this, scans still work normally.

2. Paste Real Prompts

Copy any text your team typically sends to ChatGPT, Claude, Copilot, or other AI tools. This could be code snippets, Slack messages, emails, support tickets, or config files. The more realistic, the better.

3. Or Use Sample Scenarios

Not sure what to test? Click one of the 4 sample buttons (API Key Leak, Patient Record, AWS Config, Network Scan) to load a realistic scenario and see the scanner in action.

4. Review the Threat Report

Each detected threat shows the exact match, severity level (Critical/High/Medium), impact assessment, and two levels of fix recommendations — a quick fix and a permanent solution.

5. Understand What You Need

This free scanner uses regex patterns. HoundShield Pro uses 13 AI models that understand context — it knows "Apple" in a recipe is not the same as "Apple" the company. That's why you need the full package.
