Here's how it works

When a leak happens, getting to the source should take minutes — not months. LeakLocked compares the leaked artifact against every marked copy you sent.

  1. Investigation dialog with upload a file and enter text options

    Step 1

    Upload the leaked artifact

    Paste leaked text, upload a screenshot, or provide an image of a printed or photographed document. LeakLocked extracts content with AI-powered OCR when needed.

  2. Selecting the original sent message for leak investigation

    Step 2

    Match against sent versions

    Point LeakLocked to the original message or document. We already have every individualized copy on file — each with its own unique textual signature profile.

  3. Investigation report with signature matches and confidence scores

    Step 3

    Get a ranked forensic report

    LeakLocked scores each recipient's version by matched signature options — including partial leaks — and ranks suspects by confidence so your team can act on evidence.
