What is dark web monitoring?

It's continuous scanning of the parts of the internet where stolen data is traded — breach dumps, criminal marketplaces, forums and paste sites — for your company's credentials and sensitive information. When a match is found, you're alerted so you can act before the data is abused.

How would my company's data end up there?

Usually through breaches of third-party services your staff used the same password on, phishing, or info-stealer malware. Even if your own systems are secure, a breach at another provider can expose a reused password that unlocks your accounts.

What do we actually do when something is found?

We tell you exactly which account and what data is exposed, then guide immediate action — force a password reset, enforce MFA, revoke sessions and check for signs of misuse. For managed clients we handle much of this for you.

Is this a replacement for other security?

No — it's an early-warning layer. It works best alongside identity protection, MFA and email security, turning a leaked credential into a managed alert rather than a silent breach waiting to happen.

Is it managed for us?

Yes. CLI Secure sets up the monitoring scope, watches the alerts 24/7, filters out the noise and helps you remediate real exposures quickly.

Breaches you never hear about become your problem

When another company gets breached, your staff's reused passwords end up in dumps traded by criminals. Attackers buy them and quietly log in. We find those leaks first and turn them into an alert you can act on in minutes.
