What this dark web scan checks
This free dark web scan checks the business email addresses you enter against billions of leaked records from known data breaches, the same exposed data that circulates on the dark web. For each address it reports which breaches it appears in, the year of each breach, and the type of data that was exposed. Addresses that show up alongside leaked passwords are flagged in red, because those are the ones an attacker can try directly against your Microsoft 365 login.
We never see, request, or store passwords. The scan only reports which breaches an address appears in and what category of data was exposed. A clean result is a snapshot, not a guarantee, so strong sign-in protection still matters as new leaks surface over time.
One per line. Start with the obvious ones: the owner, office manager, and any shared inbox like info@ or billing@.
We never see, request, or store passwords. We only report which breaches an address appears in and what kind of data was exposed.

Found in a breach? That is the easy part to fix.
Exposed credentials only become a break-in when an attacker can reuse the password. We close that door across your Microsoft 365 with phishing-resistant MFA, weak sign-in methods turned off, and monitored access. Most leaked passwords stop mattering the day we are done.
Book a 15-minute reviewHow business data ends up on the dark web
Business logins reach the dark web through a few common paths, and knowing them helps you understand what this scan finds. The most familiar path is a data breach. Attackers break into a company you have an account with, copy the user database, and the stolen emails and passwords get traded or dumped online. Your address can appear in a breach of a vendor or app you barely remember signing up for.
A second path is the infostealer log. Infostealer malware quietly infects a device, harvests saved browser passwords and session data, and sends everything back to the attacker. These logs sell in bulk on dark web markets, and they are dangerous because they capture passwords exactly as your team typed them.
A third path is the combo list. Criminals merge millions of leaked email and password pairs from many breaches into one searchable file, then run those pairs against business logins like Microsoft 365 to see what still works. This is why a password reused across accounts is such a risk. This free dark web scan checks your business email addresses against this kind of leaked breach data, so you can see your exposure before an attacker tests it.
Dark web scan versus continuous monitoring
A dark web scan is a one-time snapshot. It tells you which of your business email addresses appear in known breach data right now, which is the fastest way to find exposure you did not know about. A clean result today is good news, but it is not permanent, because new breaches surface constantly and a fresh leak can expose an address tomorrow that looked clean this morning.
Continuous monitoring is the ongoing answer. Instead of checking once, monitoring watches for new exposures and alerts you when one of your accounts shows up in a fresh breach, so you can rotate the password before anyone uses it. Wolferdawg IT Consulting builds that monitoring into managed protection for small businesses across Lawton, Duncan, and Southwest Oklahoma, alongside phishing-resistant MFA and locked-down sign-in. The free scan shows you where you stand today, and monitoring keeps you covered after that.
Dark web scan common questions
Plain answers about what the dark web scan checks, what your results mean, and what to do next.
What is a dark web scan?
A dark web scan checks your email addresses against large collections of credentials that have leaked from known data breaches and ended up circulating online. This tool runs that check against billions of breached records and reports which of your addresses appear in a breach, the year it happened, and what type of data was exposed. It tells you in seconds whether your logins are already in the wrong hands.
How does a dark web scan work?
This dark web scan takes the business email addresses you enter and checks them against billions of records leaked from known data breaches, the same data that circulates on the dark web. For each address it reports every breach it appears in, the year of the breach, and the type of data exposed, and it flags any breach that leaked a password. The check runs in seconds in your browser, and it never asks for or stores a password, so you see your exposure without putting any new information at risk.
How do I know if my email is on the dark web?
Enter your business email addresses above and run the scan. For each address the tool reports every known breach it appears in and flags any breach that exposed a password in red. If an address comes back with passwords exposed, that login is circulating where attackers can find it, and it should be changed and protected right away.
What should I do if my email is on the dark web?
Change the password on that account immediately, and anywhere else the same password was reused. Then turn on phishing-resistant multifactor authentication so a stolen password alone cannot get anyone in. A leaked password is only dangerous while it still works, so rotating it and adding strong sign-in protection closes the door. Wolferdawg IT Consulting can handle this across your Microsoft 365 for you.
Is this dark web scan really free?
Yes. The scan is free, requires no account, and runs instantly in your browser. Enter your business email addresses, run the check, and read the results on the spot. There is no signup and no obligation.
Is it safe to enter my email address?
Yes. The scan never asks for, sees, or stores a password. It only looks up whether an address appears in known breach records and reports the categories of data that were exposed. Entering your address simply shows you what an attacker could already find.
Can I scan my whole company at once?
Yes. Enter every business email address you want to check, one per line, including the owner, office manager, and shared inboxes like info@ or billing@. The tool scans up to twenty-five addresses in a single run, so you can see your company exposure in one pass rather than checking accounts one at a time.
What is the difference between a dark web scan and dark web monitoring?
A dark web scan is a one-time check that shows which of your business email addresses appear in breach data right now. Dark web monitoring is an ongoing service that watches for new exposures and alerts you when one of your accounts shows up in a fresh breach. The scan is the snapshot, and monitoring is the early warning that follows. Wolferdawg IT Consulting builds continuous monitoring into managed protection for businesses across Lawton, Duncan, and Southwest Oklahoma.
Can you remove your information from the dark web?
No one can erase data once it has leaked and spread across the dark web, and any service that promises full removal is not being honest. The realistic fix is to make the leaked data useless. Change every exposed password, stop reusing passwords across accounts, and turn on phishing-resistant multifactor authentication so a stolen password alone cannot get anyone in. Wolferdawg IT Consulting handles this across your Microsoft 365 so leaked credentials stop being a way in.
