How to Check If Your Data Is on the Dark Web (2026 Guide)

Your email address, passwords, or credit card numbers might be circulating on the dark web right now — and you would never know unless you check.

In 2024, over 4,100 data breaches were publicly disclosed worldwide — roughly 11 per day. The largest single breach exposed approximately 2.9 billion personal records (National Public Data incident). In the US, the FBI received 859,532 internet crime complaints in 2024, with losses exceeding $16 billion (FBI IC3).

This article shows you how to check for free right now and what to do if your data has been leaked.

Google's Dark Web Report Is Gone

On February 16, 2026, Google shut down its Dark Web Report. This free tool let you check whether your Gmail address appeared in known data breaches. It no longer exists.

Similarly, Mozilla Monitor Plus (the paid tier of Firefox Monitor) was discontinued in December 2025.

Two major free dark web monitoring options disappeared in quick succession. But alternatives exist — and some are better than what Google offered.

What Happens When Your Data Ends Up on the Dark Web

The dark web is a part of the internet only accessible through anonymizing tools like the Tor browser. Stolen data is bought and sold there in bulk.

If your information is on the dark web, here is what can happen.

• Credential stuffing — attackers take your leaked email/password combination and try it on other services. If you reuse passwords, the damage cascades
• Targeted phishing — leaked email addresses receive precision phishing campaigns tailored to the breached service
• Identity fraud — if your name, address, and phone number leak as a set, attackers can open accounts or loans in your name
• Credit card fraud — leaked card numbers lead directly to unauthorized charges

Free Tools You Can Use Right Now

All of these are free and some require no account creation.

Have I Been Pwned (HIBP)

The most trusted leak-checking tool. Run by security researcher Troy Hunt, it indexes 959+ breached sites and over 12 billion records.

How to use it:

1. Go to haveibeenpwned.com
2. Enter your email address or phone number
3. Click "pwned?"

If the result is red, you will see a list of breaches that included your email — the service name, breach date, and types of data exposed (email, password hashes, names, etc.).

NordPass Free Dark Web Scan

NordPass offers a free one-time scan. No account required.

How to use it:

1. Visit the NordPass dark web scan page
2. Enter your email address
3. Review the results

It checks against NordPass's own breach database in addition to public sources, so results may differ from HIBP. Check both for the most complete picture.

Firefox Monitor

Mozilla's breach-checking tool. It uses HIBP's database on the backend, so results are similar, but the UI is cleaner and more beginner-friendly.

How to use it:

1. Go to monitor.mozilla.org
2. Enter your email address
3. Review the results

Tool Comparison

Start with HIBP and NordPass. It takes under two minutes.

Paid Services for Continuous Monitoring

Free tools check the current moment. Paid services notify you in real time when a new breach includes your data — that is the key difference.

NordPass Premium Data Breach Scanner

NordPass Premium includes a data breach scanner that monitors your email addresses and credit card numbers 24/7 and sends instant alerts when a new breach is detected.

It combines password management with dark web monitoring in one tool. For a full review, see "NordPass Review."

NordVPN Dark Web Monitor Pro

NordVPN's Complete and Prime plans include Dark Web Monitor Pro, which covers a broader range of personal data.

If you want VPN + password manager + dark web monitoring in one subscription, NordVPN Complete is the most practical option. See "NordVPN Full Review" for details.

What to Do If a Leak Is Found

If your check returns results, here is the response playbook.

Step 1: Identify What Was Exposed

HIBP and NordPass results show the breached service and the types of data involved. Whether passwords were included is the most critical piece of information.

Step 2: Change Passwords on Affected Services

Change the password on the breached service immediately. If you reused that password elsewhere, change it everywhere.

For password management guidance, see "Can't Remember Your Passwords? You Don't Have To."

Step 3: Enable Two-Factor Authentication

Set up 2FA on every service that supports it. Authenticator apps (Google Authenticator, Microsoft Authenticator) are safer than SMS.

Step 4: If Credit Card Data Was Exposed

Contact your card issuer and request a new card with a new number. This is the only way to fully prevent further unauthorized use. Review recent statements for charges you do not recognize.

Step 5: Check for Identity Fraud

• US: Request free credit reports from all three bureaus at annualcreditreport.com. Consider a credit freeze at Equifax, Experian, and TransUnion
• UK: Check your credit report with Experian, Equifax, or TransUnion UK
• File a report: In the US, report identity theft at IdentityTheft.gov. For general cybercrime, contact your local FBI field office or use ic3.gov

How to Minimize Your Exposure

You cannot prevent a service from being breached. But you can limit the damage when it happens.

Stop Reusing Passwords

Use a different password for every service. If one leaks, only that service is compromised. A password manager handles the complexity.

Use Separate Email Addresses

Keep your primary email for critical services (banking, main social media). Use a separate address for signups, promotions, and trials. This reduces the chance your important address ends up in a breach list.

Delete Unused Accounts

Every dormant account is a liability. If you no longer use a service, delete your account. Fewer accounts means fewer breach exposure points.

Encrypt Your Traffic with a VPN

Reduce the risk of interception on public WiFi. For a primer on VPN basics, see "What Is a VPN? A Beginner-Friendly Explanation."

Wrapping Up

With Google's Dark Web Report gone, you need to take monitoring into your own hands.

• Check now with Have I Been Pwned and NordPass free scan — it takes two minutes
• If a leak is found: change passwords → enable 2FA → replace cards (if applicable)
• For continuous monitoring, consider NordPass Premium or NordVPN Complete
• Prevention: unique passwords, separate emails, delete unused accounts

Go check your email address right now. The result might be uncomfortable, but not knowing is far more dangerous than knowing.
