We could identify data that was part of a legacy breach, data that existed on national suppression files along with detailed phone and email validation flags. Really impressive solution and would recommend to anyone onboarding new data or to check existing datasets. It enabled us at Dataxcel to make informed decisions especially around compliance."

What Provero checks, how fast it runs and what it costs.
Whether an email address, phone number or IP appears in known breach data, how many separate breaches, and how old the first one is. That last figure does most of the work.
On a single record it means very little, because around half of real consumer data carries breach exposure. It works across a whole source. Clean sources run at roughly 50% exposure with a first breach three to five years old. Recycled stolen data runs at 70% to 100%, with a first breach nine to eleven years old, and the same records turning up in six or more breaches each. A supplier can lower a breach rate. Nobody can make old data young.
We call that read the Breach Age Index.
