What is the dark web?
The dark web is a small, hidden layer of the internet that ordinary search engines don’t index and that you can only reach with special software like Tor. It’s used for privacy — and for crime: passwords, IDs and financial details stolen in data breaches are bought and sold there.
The dark web is a small, hidden part of the internet that search engines don’t index and that you can only reach with special software like Tor. It’s used for privacy — and for crime: passwords, IDs and financial details stolen in data breaches are bought and sold there. You can’t erase data once it’s leaked, but you can check what’s exposed and lock those accounts down.
Dark web vs. deep web
People mix these up. The deep web is simply everything search engines don’t index — your email inbox, online banking, internal company databases — most of it ordinary and protected by a login. The dark web is a tiny corner of the deep web you can only reach with anonymizing software like Tor. The surface web (what Google shows) is the small visible tip; the dark web is the deliberately hidden, anonymous layer below it.
What’s actually sold on the dark web?
Alongside legitimate privacy uses (journalists, activists, people under censorship), the dark web hosts anonymous marketplaces. The goods that matter for your privacy are stolen personal data: email-and-password combos, full identity profiles (“fullz”), Social Security numbers, scans of IDs, and payment-card numbers — often sold in bulk for a few dollars each.
How does your data end up there?
Almost always through a data breach. A company is hacked, the stolen database is dumped, and the records are copied and resold across dark-web markets for years. The FBI’s Internet Crime Complaint Center (IC3) logs hundreds of thousands of cybercrime complaints and billions of dollars in reported losses every year (IC3 annual reports). Data brokers make it worse: they keep your address, phone and relatives public, giving criminals the extra details that turn a leaked password into full-blown identity theft.
Is the dark web illegal?
Accessing it isn’t. Tor is legal to use in the U.S., and the network was originally built for privacy and free expression. What’s illegal is a lot of the activity — buying stolen data, drugs or weapons. For an ordinary person there’s no safe reason to browse dark-web markets: you can’t remove your data by going there, and you expose yourself to malware and scams.
Signs your data may be on the dark web
Watch for a sudden spike in spam or phishing, login alerts and password-reset emails you didn’t request, charges you don’t recognize, or notices that an account was accessed from a new device. Identity theft is consistently one of the most-reported complaint categories to the U.S. Federal Trade Commission (IdentityTheft.gov). The reliable way to know is to check your email against known breach databases rather than browse the dark web yourself.
What to do if your data is exposed
You can’t delete leaked data, but you can shut the door on it. Start by checking what’s exposed with our free breach & dark-web check, then change the password on every breached account (and anywhere you reused it), turn on two-factor authentication, and freeze your credit. Security agencies including CISA stress unique passwords and MFA — reusing one password is exactly what turns a single leak into account takeovers everywhere else (CISA: Secure Our World). Finally, remove your data from brokers via our free data-broker opt-out guide so there’s less to steal — see the full playbook on removing your personal information from the internet.

Is it illegal to access the dark web?
No. The dark web is just a part of the internet you reach with privacy software like Tor, and using Tor is legal in the United States. What can be illegal is what some people do there — buying stolen data, drugs or weapons. Simply browsing is not a crime, but it is risky.
What is the difference between the deep web and the dark web?
The deep web is everything search engines don’t index — your email inbox, online banking, private databases — most of it perfectly ordinary and protected by a login. The dark web is a tiny subset of the deep web that you can only reach with special software like Tor, and it’s where anonymous marketplaces (including ones selling stolen data) live.
How do I know if my personal information is on the dark web?
You can’t browse the dark web safely to look. Instead, check your email address against known breach databases — that’s the most common way personal data reaches the dark web. Our free breach & dark-web check tells you instantly whether your address has appeared in a known leak, with no signup.
Can you remove your data from the dark web?
No — once data is leaked and copied across anonymous servers, it can’t be deleted. What you can do is limit the damage: change exposed passwords, turn on two-factor authentication, freeze your credit, and remove your data from the data brokers that keep rebuilding a public profile of you so there’s less to steal next time.
Is dark-web monitoring worth it?
It’s useful as an early-warning system: it tells you which of your accounts were exposed in a breach so you can change those passwords before someone uses them. But monitoring is reactive — it can’t remove anything. Pair it with strong, unique passwords and data-broker removal for actual protection.
