Misdirected fax transmissions are among the most common HIPAA breach types — and most are preventable. FaxDx searches 6 signals to surface the most likely current fax number for any provider, then probes the line live to confirm it answers as a working fax. Every check creates a timestamped audit record — provider, number, result, who ran it — exportable as PDF anytime. No PHI ever touches FaxDx. Free to start.
Hey Product Hunt 👋
I built FaxDx after learning that misdirected fax is one of the most common HIPAA breach types — and that most healthcare organizations have no real process for verifying fax numbers before sending patient records.
The root problem: NPPES (the national provider registry) is self-reported and rarely verified. Over 40% of NPI records have no fax number at all, and many that do are years out of date.
FaxDx fixes this in two steps:
1. Searches 6 signals (payer directories, co-located providers, web presence, received fax history) to surface the most likely current number
2. Probes the line live to confirm it answers as a working fax
Every check gets a timestamped audit record you can export as PDF — the exact documentation OCR requests in a HIPAA investigation.
No PHI ever touches FaxDx. Free to start. Would love your feedback!
