Your team's passwords,
for sale on the dark web?
When an employee reuses a password and a third-party service gets breached, your company ends up in the next credential-stuffing attack. We monitor breach databases and paste sites for credentials tied to your domain, and alert you the moment something surfaces.
For business domains. For personal email breach lookups, use haveibeenpwned.com — we don't compete with that.
A one-time lookup isn't a monitor.
A single check today tells you about yesterday. New breaches surface constantly, and credential-stuffing attacks start within hours of a dump going public. Monitoring is the difference between knowing in 3 hours or 3 months.
Continuous alerting
Ongoing monitoring against breach databases, paste sites, and combolists. Email alert within hours of your domain appearing in new dump.
Domain-wide coverage
Every address under your domain monitored — not just the ones you remembered to enter. Role accounts, aliases, former employees, all included.
Context, not just a hit
Each exposure tagged with source breach, date, what data leaked (password/hash/plaintext), and remediation step. Rotate-and-notify workflow built in.
Built for SMBs in the gap nobody serves.
One free lookup tool. One $10K/year enterprise platform. Nothing reasonable in between — until now.
