Find out what of yours has leaked. Then lock it down.
Your data is sitting in breaches you were never told about. Bulwark shows you which ones, proves it with documented evidence, and walks you through the fix in plain language. Built for people, not just security teams.
your own address only · we never reveal the stolen data · we never see your password
Proof of what leaked, and a plan to fix it.
See exactly where you were exposed.
We check your address against known breaches and show the documented evidence: which breach, when it happened, how many accounts it hit, and what categories of data were taken. We show that you were in it, never the stolen data itself.
A guided plan, in plain language.
An ordered checklist that starts with the two steps that close most of your risk. Plus a password check that runs entirely inside your browser, so we never see the password you are testing.
Four steps, about five minutes.
No security knowledge needed, and nothing to install.
- 01
Create an account
We email you a 6-digit code. Typing it back is also how we confirm the address is really yours, which is the only reason we ask you to sign in at all.
- 02
Run the check
One click. We check your verified address against known breach records. Your email is used for the check and is never stored.
- 03
Read the proof
Which breach, when it happened, how many accounts it hit, and what categories of data were taken. Documented evidence you can verify elsewhere, never the stolen data itself.
- 04
Work the plan
An ordered checklist starting with the two steps that close most of your risk. The result is saved to your history so you can see things improve over time.
We only check an address you have proved you control.
Plenty of sites will look up anyone's leaked data for you. That is surveillance sold as safety, and we will not build it. Signing in is how we know the address is yours, which is the whole difference between a personal security tool and a people-search engine.
The result, not the data.
How many exposures, whether a password was among them, the risk level, and the date. We do not store the address you checked, and you can delete your history at any time from your account page.
Show you someone else's life.
No lookups on other people. No reselling what we find. Threat research is aimed at attacker infrastructure such as scam domains and wallets, never at private individuals.
Pay per checkup. No subscription.
One payment, one full checkup on your own address. Nothing recurring, no card kept on file for a plan you forget about.
per checkup, paid once. No subscription and no card kept on file.
- Your verified address checked against known breaches
- Documented proof for every exposure we find
- An ordered fix plan, written in plain language
- A password check that runs in your browser, not on our servers
- Your full checkup history, deletable any time
Checkout is not built yet, so checkups cost nothing today and no card is asked for. The price above is what one will cost once it is.
The questions people ask first.
Is this legal?
Yes. We check an address you have proved you control against records of breaches that are already public. There is no hacking involved, and we will not look up anyone but you.
Why do I have to sign in first?
Because that is how we know the address is yours. A checkbox saying "this is mine" is a claim, not proof. Without real verification this would be a people-search engine for other people's leaked data, which is the one thing we will not build.
What do you actually store?
The result only: how many exposures were found, whether a password was among the leaked data, the risk level, and the date. We do not store the address you checked, and we never store the leaked data itself. You can delete your whole history from your account page in one click.
Can you see the password I test?
No, and we designed it so we cannot. Your browser fingerprints the password locally and sends only the first five characters of that fingerprint. The password never leaves the page, and we could not reconstruct it from what we receive.
Can I check my partner's or my company's email?
No. Only the address you have verified. Checking a second address you own yourself is coming, and it will require proving you control that one too.
What if nothing shows up?
Good news, but read it precisely: it means nothing was found in the sources we can see, not that you were never exposed. Keep unique passwords and two-factor authentication on anything that matters.
What happens after I fix things?
Run the check again whenever you like. Each result is saved, so your history shows whether your exposure is going down as you work through the plan.
Find out what an attacker already knows about you.
Create an account, verify your address, and run your first checkup in minutes.
