Solution · Leaked Credentials Monitoring

Leaked Credentials Monitoring, powered by Agentic AI.

Most breaches start with a stolen password. Quantum watches the dark web, breach dumps and infostealer logs and alerts you the moment your credentials leak — so you can reset before an attacker logs in.

What is leaked credentials monitoring?

Leaked credentials monitoring continuously scans dark-web markets, breach dumps, combolists and infostealer-malware logs for your organization’s exposed usernames, passwords and session tokens. Quantum matches leaks to your domains, employees, executives and customers, shows whether passwords are plaintext, hashed or salted and how recent the leak is, and delivers prioritised alerts with evidence — so you can force resets and block account takeover before attackers act.

How Quantum monitors leaked credentials

Breach & combolist coverage

Monitors data breaches, combolists and credential dumps across dark-web markets and paste sites.

Infostealer log monitoring

Tracks stealer-malware logs (RedLine, Lumma and more) that leak live session cookies and credentials.

Employee & executive exposure

Flags corporate email and executive credentials the moment they surface — before account takeover.

Customer & domain protection

Detects leaked customer credentials tied to your domains, reducing fraud and ATO risk.

Password & hash context

Shows whether a leak includes plaintext, hashed or salted passwords, and how recent it is — so you prioritise resets.

Real-time alerts

Severity-scored alerts within minutes, with evidence and the affected accounts.

Leaked credentials monitoring — FAQ

Will you alert me before an account is taken over?

That’s the goal. Quantum surfaces leaked credentials within minutes of appearing, so you can force a reset before an attacker uses them.

Do you cover infostealer (stealer-malware) logs?

Yes. Beyond breach dumps and combolists, Quantum monitors stealer logs (e.g. RedLine, Lumma) that leak live credentials and session cookies.

Can you monitor our customers’ credentials too?

Yes. Quantum detects leaked credentials tied to your domains for both staff and customers, reducing fraud and account-takeover risk.

Do you store our passwords?

No. Quantum flags exposure and context (e.g. plaintext vs hashed, recency) so you can act — without you having to hand over sensitive secrets.
