Dark Web Scan

Enter your corporate domain in our dark web scanner to search criminal marketplaces and hacker forums for your organization’s exposed credentials. The scan checks combo lists and stealer logs, plus third-party breach dumps, in seconds. This one-time check shows current exposure, but continuous monitoring is recommended since new breaches happen daily. Compromised credential monitoring tracks ongoing threats to your organization.

A dark web scan for business checks whether your company’s credentials or employee emails have been exposed on criminal marketplaces. Unlike consumer scanners that check a single personal email, a business dark web scan checks your entire domain and shows exposure across departments. The results tell you which accounts are compromised so your security team can reset passwords before attackers log in.

Run our dark web scan with your company domain. You’ll see an instant results view showing exposed credentials and the breaches they came from. For continuous coverage, dark web monitoring delivers real-time alerts as new exposures appear, either as JSON webhooks into your SIEM or SOAR or as HTML email to your security team.

A dark web scan is a search of hidden parts of the internet for your organization’s stolen credentials or sensitive data. A dark web scan tool automates this process, checking hacker forums and criminal marketplaces where stolen credentials are commonly sold or shared.

A data leak checker (also called a data breach checker) scans stealer logs and criminal marketplaces to find your exposed credentials. It tells you if your email or company data has been leaked. Our data breach checker searches billions of records from third-party breaches and infostealer malware logs. When your data appears, you can reset passwords before attackers exploit them.

A dark web scan tool crawls hidden parts of the internet for your organization’s exposed email addresses and passwords. When it finds relevant data, you get an alert with details so you can take action - like resetting passwords or locking down accounts. The best scan tools run continuously, keeping you informed about new threats as they appear.

If your data is found on the dark web, take immediate action. First, reset passwords for all affected accounts and enable multi-factor authentication. Next, inform employees whose credentials were exposed and require password changes. Consider implementing data breach monitoring to detect future exposures before attackers can exploit them. For help evaluating continuous monitoring solutions, see our comparison of the best dark web monitoring services. Document the incident for compliance requirements and review how the breach occurred to prevent similar incidents. The NIST Cybersecurity Framework provides detailed guidance on incident response procedures.

You should scan for dark web exposure continuously, not just once. New stealer logs and combo lists appear daily on criminal marketplaces. A one-time scan shows your current exposure, but doesn’t protect against tomorrow’s breach. Continuous monitoring with real-time alerts lets you respond to new threats immediately. This is why security teams use automated dark web monitoring platforms instead of periodic manual scans.
