Free dark web scan for business email
See which company logins are already exposed before an attacker does. Powered by Wolferdawg IT Consulting in Lawton, Oklahoma.
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@.

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.

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 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.
