Exactly what happens to your URLs — nothing more, nothing less.
🖥️
Your machine
You paste URLs into the box. That's it — no email content, no attachments, no sender details, no message body ever leaves your browser. Only the raw URLs you explicitly submit are processed.
URLs only
🔍
VirusTotal
Each URL is checked against VirusTotal's database of 90+ security engines. This is identical to what your team already does manually — pasting URLs into virustotal.com. ThreatAssist just automates it.
URLs sent
🌐
URLScan.io
Suspicious URLs are submitted to URLScan's sandbox for live analysis. Scans are set to unlisted — they are not publicly searchable. Same as visiting urlscan.io manually but automated.

Claude AI (Anthropic)
The scan results — not the URLs themselves — are sent to Claude to generate the verdict and reasoning. Anthropic's API policy explicitly states data sent via API is never used for model training.

ThreatAssist servers
Nothing is stored. No database, no logs of what you scanned, no email content, no user accounts. Each analysis is processed in memory and discarded. The server never sees your email — only URLs you paste.
Nothing stored
In plain English: ThreatAssist does exactly what your analysts already do manually — paste URLs into VirusTotal and URLScan — but faster and with an AI summary on top. The data flow is identical to your existing workflow. No sensitive company data ever leaves your control.
