Our mission

Nobody should find out
they were a breach victim
when it's already too late.

PassMonitor was born from a simple idea: what if everyday people had access to the same kind of information that hackers and security experts already know?

The problem nobody tells you about

Every day, thousands of databases are breached around the world. Emails, passwords, names, ID numbers, phone numbers... billions of personal records circulate freely in layers of the internet most people don't even know exist.

The scariest part? Most victims never find out. They keep using the same password on every site, unaware their data is already in the wrong hands. Until one day they get a strange charge, lose access to an account, or fall for a scam that seemed impossible.

Companies that suffer breaches don't always notify their users. Sometimes out of embarrassment, sometimes because they're not legally required to, and sometimes because they haven't even discovered they were breached.

Our answer: information is the best defense

Alert before it's too late

Most people only find out their data was leaked after falling for a scam. We exist to flip that logic: we want you to know before the criminals do.

Educate without complicating

Digital security shouldn't be a topic only for experts. We translate technical information into language anyone can understand and act on.

Protect those who need it most

Digital scams disproportionately affect those with less access to information. Our tool is free because we believe basic security is a right, not a privilege.

How we do it

We developed specialized artificial intelligence that analyzes unstructured information circulating in deep layers of the internet. Our automated robots work around the clock, monitoring known breach databases and cross-referencing this data in real time.

When you enter your email on PassMonitor, within seconds our technology checks whether your data appears in any of the more than 950 cataloged breaches, which together total over 17 billion compromised records.

Most importantly: we don't store your data. Every check uses end-to-end encryption, happens in real time, and nothing is saved on our servers after you close the page.

17B+ accounts monitored
950+ breaches tracked
0 of your data we store
100% free for individuals

Why is it free?

Because we believe knowing whether your data has been exposed is a basic security right, not a premium service. Those most affected by digital scams are precisely the people who can't afford protection tools.

Our model is simple: personal checks are and always will be free. For businesses that need continuous monitoring, real-time alerts, and API integration, we offer corporate plans that sustain our operation and allow us to keep the service open to everyone.

Who's behind it

What we are not

We are not hackers. We don't break into systems, we don't buy data, and we don't participate in any kind of illicit activity. We work exclusively with information that has already been made public after a breach.

We don't sell your data. Ever. To anyone. Our business model doesn't depend on exploiting our users' information. It depends on protecting it.

We don't replace a security expert. We are an alert and education tool. For serious or enterprise cases, we always recommend consulting qualified professionals.
