If You Don't Have One, I Recommend a Free Dark Web Monitoring Service

"Most of the time when data is available, it's not the dark web, it's the clear web. While it's true that data might also be shared on the dark web, the vast majority of compromised data is found on publicly accessible hacker forums and markets. The availability of the data is what makes a so-called dark web monitoring service, also known as a data breach monitoring service, possible."

"It's essentially a database of data breaches the service has found online. You sign up for the service by providing your personal data. An email address is most common, but some may also ask for a phone number or even your credit card information. The monitoring service can then alert you to any existing matches in its database and send you a notification if any new breach occurs in the future."

"Now more than ever, there is an abundant lack of disclosure from breached organizations. If the data is out there, the odds are good that it's been reported. The infrastructure feeding breaches into modern dark web monitoring databases is extensive and sophisticated."

Data breaches have reached epidemic levels, with over 12,000 breaches recorded in 2025 alone. Organizations increasingly fail to disclose breaches transparently. Dark web monitoring services provide a critical defense by tracking compromised data across the internet. Despite their name, these services primarily monitor publicly accessible hacker forums and markets on the clear web rather than specialized dark web areas. Users register with their personal information, typically an email address, and receive alerts when their data appears in existing breach databases or new breaches occur. The infrastructure supporting these services is extensive, drawing data from law enforcement and other sources to maintain comprehensive breach databases.
