How NordStellar’s dark web monitoring works
NordStellar’s dark web monitoring provides businesses with real-time visibility into stolen or leaked data. By continuously scanning the dark web, it helps you detect breaches early and prevent potential threats.
NordStellar constantly scans the deep and dark web sources — from hidden forums to Telegram channels and ransomware blogs — detecting new leaks the moment they appear. Instead of a single snapshot, continuous monitoring gives you ongoing awareness of new risks as they emerge.
Monitor mentions of your company, employees, or partners across thousands of sources. From domains and emails to specific keywords or vendors, NordStellar helps you identify potential risks with both one-time searches and ongoing tracking.
Get notified the moment a new threat is detected — directly in email, Slack, Microsoft Teams, or other preferred channels. Automated alerts ensure your security team can respond before an incident grows.
Each detected mention comes with rich context — including links, author, and source details, sometimes even screenshots — so you can take action with confidence.
Deep and dark web forums
With many years of experience monitoring the deep and dark web, NordStellar has access to one of the largest data pools, detecting emerging threats across thousands of dark web forums.
Dark web marketplaces
NordStellar closely monitors major dark web marketplaces. Gain early visibility into your company’s compromised information and sensitive data being sold illegally.
Telegram channels
NordStellar actively monitors tens of thousands of cybercrime Telegram channels used for fraud, phishing, and identity theft. Quickly detect threats and prevent potential incidents.
Ransomware blogs
Hundreds of ransomware blogs are tracked to help assess threats of ransomware and data leaks. Identify risks of your organization being targeted by ransomware and prevent these devastating attacks.

FAQ
Dark web monitoring is a solution that continuously scans hidden sources – like forums, marketplaces, and ransomware blogs – for exposed company data such as credentials or domain mentions. By alerting you the moment sensitive information appears, NordStellar helps your team respond quickly and prevent potential cyber incidents.
Yes. Dark web monitoring is completely safe because it doesn’t expose or share your company’s sensitive data. NordStellar monitors external sources – such as dark web forums, marketplaces, and ransomware blogs – and matches them against known identifiers like domains or email addresses without accessing your internal systems.
A one-time scan gives you a snapshot of your current exposure, but monitoring the dark web ensures ongoing visibility as new leaks and mentions appear daily. Alerting you the moment new risks emerge helps you respond before threats cause actual harm.
If NordStellar detects exposed data, your security team should immediately reset any compromised passwords, investigate potential breaches, and review access controls. The platform provides full context – including source links and timestamps – to help verify and contain the exposure quickly.
The free dark web scanner is a quick online tool that lets you see an example of leaked data linked to your company email. NordStellar’s full dark web monitoring solution provides continuous, automated scanning across thousands of sources, real-time alerts, and detailed intelligence for ongoing protection.
Yes, the free scan is completely secure. It only checks your work email against existing breach databases and does not collect, share, or store sensitive information beyond what’s needed to show your results.
You’ll see a summary of whether your company email appears in known breaches, along with examples of exposed data types. The report offers a preview of the insights available in NordStellar’s full dark web monitoring platform.
No. Your email is used only to perform the scan and generate your report. NordStellar does not store or reuse your information once the results are displayed.
