Ethical (white-hat) hacker · Founder of Reconvio
I break into websites legally, so their owners can close the holes before someone with bad intentions finds them. Reconvio is that work turned into a tool anyone can run in 30 seconds — the same outside-in audit I do by hand, made instant and free.
Why I built Reconvio
Most website owners never find out what they're exposing until it's too late — a leaked API key drains an account, an open database ends up for sale, a missing legal notice turns into a fine. Almost all of it is preventable, and the evidence is sitting right there in the site's own responses. It just takes someone who knows where to look.
I kept seeing the same avoidable mistakes on site after site — especially on sites built fast, and increasingly by AI. So I turned what I check by hand in an audit into an automated tool that gives you the same answers in seconds, in plain language, for free.
How I work
Reconvio inspects your site the way I do in a real audit — from the outside, exactly the way an attacker and a search engine see it.
- Only what your site already serves to every visitor — no guessing passwords, no breaking in, nothing destructive.
- Every finding traces back to a real vulnerability seen in practice, not a checklist copied from theory.
- Explained in plain language: what's wrong, why it puts you at risk, and exactly what to do about it.
- We inspect from the outside and store nothing beyond your report — your privacy matters as much as your security.
What I focus on
The ground this tool is built on — and where I spend my days.
