What LeakLocked does
LeakLocked helps you trace information leaks back to the individual who received them.
When you send sensitive emails or documents, LeakLocked:
- Detects natural places in your content where wording can vary without changing meaning (lists, interchangeable phrases, and similar patterns).
- Generates a unique version for each recipient.
- Sends individualized copies via the web app or Outlook add-in.
- Investigates leaked content by matching it against every sent version.
- Reports ranked results with confidence scores.
Recipients see normal, readable content. The differences are subtle enough to be imperceptible in day-to-day reading, but strong enough for forensic matching if content leaks.
