Dark Web Monitoring

Dark web monitoring services scan illegal marketplaces and data dumps for your personal information — SSN, email, passwords, credit card numbers. Here's what these services actually do, what they can and can't find, and whether they're worth using.

What the Dark Web Is

The "dark web" refers to websites and forums accessible only through specialized software (primarily Tor) that obscures IP addresses and identities. It hosts significant criminal activity, including marketplaces where stolen personal data — credit card numbers, Social Security numbers, login credentials, full identity packages ("fullz") — is bought and sold.

What Dark Web Monitoring Does

Monitoring services maintain scrapers and feeds that scan known dark web marketplaces, forums, and data dumps. When your monitored information (email address, SSN, phone number, credit card numbers) appears in a newly discovered dataset or marketplace listing, you receive an alert.

What it can find: data breach dumps, credential lists, marketplaces selling your specific information.

What it can't find: private transactions, encrypted markets it doesn't have access to, data that hasn't yet been posted publicly, information sold in person or through private channels.

Is Dark Web Monitoring Worth Paying For?

Free options exist that cover the most common exposure vector — email and password combinations from data breaches. Check haveibeenpwned.com, which monitors known data breaches for free. Google's free password manager also monitors for compromised passwords.

Paid dark web monitoring (bundled with identity theft protection services like LifeLock, Experian IdentityWorks, or TransUnion Credit Lock) adds SSN monitoring, financial account monitoring, and human assistance. This is worth considering if:

• You've already been a victim of identity theft
• Your SSN was exposed in a major data breach
• You're in a high-risk profession (government, healthcare, finance)

What to Do When You Get an Alert

If your email and password appear in a breach:

• Change that password everywhere you used it
• Enable two-factor authentication on affected accounts
• Check for unauthorized access to those accounts

If your SSN or financial information appears:

• Place a credit freeze at all three bureaus immediately
• Place a fraud alert
• Review your credit reports for new unauthorized accounts
• File an FTC Identity Theft Report at IdentityTheft.gov
