Threat landscape
What the dark web sells
The dark web is a hidden network requiring special software to access. While it has legitimate privacy uses, it's primarily a marketplace for stolen data — packaged and resold within hours of a breach.
Attackers run automated credential-stuffing tools across dozens of services simultaneously. Speed is everything — ZeroAuth puts you ahead.

How it works
From breach to resolved — in four steps
Continuous breach indexing

One-tap remediation
< 30 secondsThe alert links directly to the affected vault entry. Tap "Generate new password", confirm, save — the new credential is immediately encrypted. Done in under 30 seconds.
