How we monitor data brokers, and how we get you removed

An explanation of one of the more boring but valuable parts of the watch.

The brokers are quietly the biggest leak.

Most personal-information leaks don't come from breaches. They come from data brokers, companies that aggregate publicly-collected information about you and resell it. The brokers usually have your name, your home address, your relatives' names, sometimes your phone number, sometimes your past addresses going back twenty years.

We check 38 of them, every day.

Mateo's pipeline checks 38 major data broker networks every twenty-four hours for entries against your name and your known emails and phones. When new entries appear, you get a note. The removal request is queued automatically against the broker's opt-out process.

Most of you have hundreds of records that need clearing.

When we onboard a new member, the first identity reset usually finds between 200 and 800 individual records across the broker network. We work through them in batches over the first month. After that, the daily watch keeps the count near zero.
