How Nullivo works
A breach-and-exposure scan you can trust, because it only ever looks at your own, verified email.
You prove the email is yours
Enter your email and we send a 6-digit one-time code. You can only scan an address you can receive mail at. There is no “look up anyone” box. This is the design choice that keeps Nullivo a self-protection tool, not a surveillance tool.
We check it against breach data
Once verified, we query trusted breach databases (Have I Been Pwned in production) to see which known data breaches your email appears in, and what kind of data each one exposed: passwords, names, phone numbers, and more.
We turn findings into a clear picture
Raw breach data is hard to act on. Nullivo scores your overall exposure (0-100), breaks it down by risk type, and writes a plain-English exposure summary: what your exposed data could actually be used for.
You get a prioritized fix-it plan
Every finding maps to a concrete, ranked action: change reused passwords, enable 2FA, lock your SIM, opt out of data brokers. Do the high-impact items first.
We keep watch
New breaches happen constantly. With monitoring on, Nullivo re-scans on a schedule and emails you the moment your address turns up in something new.
Why “self-only” matters
Tools that let you look up other people are banned by app stores and restricted by payment processors, and they create real legal and ethical risk. Nullivo deliberately can only scan an email whose owner just proved they control it. That single rule is what makes the product safe to run and to sell.
