What's great

I run DarkCheck regularly to scan my organisation’s domains and email addresses. It detects if any credentials have leaked onto the dark web or if there are exposed records tied to our email/brand name. The setup was straightforward and I was up and running in minutes.

What needs improvement

It would also be useful if it supported multi-user roles or allowed team members to act on alerts (for larger teams).

vs Alternatives

I considered several dark web monitoring and breach detection tools, but most were either too complex, slow, or produced vague reports. DarkCheck stood out because it is fast, easy to use, and delivers clear, actionable results. The real-time alerts, simple dashboard, and thorough coverage of past and new breaches made it an obvious choice for protecting my email and domain security.

Do you detect past, ongoing, and new breaches?

Yes. DarkCheck continuously monitors a broad range of past, active, and newly discovered breaches, including dark web forums, data dumps, marketplaces, and paste sites. The system updates daily to ensure that you’re alerted as soon as new exposures are found, helping you respond to threats in real time.

What exactly do you store about my email checks?

DarkCheck only stores non-identifiable metadata — such as the time of the scan, breach count, and anonymized hash — to provide history and reports. The actual email addresses or credentials are never saved on servers. Users can delete their scan history anytime through the dashboard for full control.

Is the email hashed or anonymized during lookup?

Yes. All email addresses are hashed and anonymized before being checked. DarkCheck uses one-way encryption (SHA-256) so the actual email is never stored or exposed during the lookup process. This ensures that no identifiable data leaves your browser or account in plain text.

It gives practical, actionable results instead of generic reports. The tools work smoothly, and the scanning accuracy is high. It saves time and makes it easy to understand exactly what needs to be fixed.
