Personal Identifiers // Detector
Find email addresses in your files
FileSentinel surfaces email addresses as personal identifiers so contact data does not leave in a shared export unnoticed.
What it detects
What FileSentinel finds
FileSentinel reads inside your files and surfaces email addresses as personal identifiers, scoring them in the context of the other PII around them. That makes it easy to spot a spreadsheet full of customer contacts versus a stray signature line.
Where it hides
- Spreadsheets and CSV exports
- Text and email exports
- Word and PDF documents
- Scanned forms (via OCR)
// RESULTS — findings scored by confidence and severity
Why it matters
The risk of leaked email addresses
Email addresses are personal data under GDPR and similar laws, and in bulk they fuel phishing and spam. They accumulate in contact exports, mailing lists, and CRM dumps.
- CRM and marketing list exports
- Contact and customer spreadsheets
- Email archives and forwarded threads
- Sign-up and registration forms
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags email addresses with a confidence and severity score, and helps you remediate. Built-in detectors cover the common cases, and a custom rule builder lets you add plain-text or regex detectors for anything specific to your work.
Score
Every finding gets a confidence and severity score, so real email addresses rise above coincidental matches.
OCR
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching email addresses in screenshots and scans.
Remediate
Redact values, mark false positives, or export a CSV, HTML, or PDF report, then share with confidence.
Private by design
Your files never leave your PC
Scanning, OCR, and remediation all happen on-device. FileSentinel makes no network connections to do its work, so the very data you are trying to protect never has to leave your machine to be checked. No server, no cloud, no upload step.

Questions & answers
Find email addresses FAQ
How do I find email addresses in my files on Windows?
Install FileSentinel from the Microsoft Store, point it at a folder or drive, and start a scan. FileSentinel reads inside your files, flags email addresses, and scores each finding by confidence and severity so the real risks rise to the top.
Is scanning for email addresses private?
Yes. FileSentinel runs entirely on your device. Scanning, OCR, and remediation all happen locally with no uploads and no cloud, so the data you are trying to protect never has to leave to be checked.
Can I focus on bulk contact lists rather than every stray address?
Yes. FileSentinel scores findings in context and lets you flag the categories you care about as Crown Jewels, so a file dense with personal contacts is escalated above a document with a single signature address.
What file types does FileSentinel check for email addresses?
FileSentinel reads inside documents, spreadsheets, text, and PDFs, and with OCR enabled it reads text inside images and scanned PDFs too, so email addresses captured in a screenshot or scan is caught as well.
