Security is our trade. A safer internet is the reason.
DomainCheckup was built by people who have spent years helping organisations get their security in order, and who felt the basics should be within everyone's reach. Not only those who can afford an auditor.
Why we built it
Anyone who makes a living in information security sees the same thing every week: a domain that can be hijacked, a mail setting that allows forgery, a certificate nobody is watching. Almost never out of unwillingness. Almost always because nobody ever measured it, and because those who could only spoke in terms that mean nothing to a business owner.
- The same checks we run for large organisations
- One grade and plain language, no eighty-page report
- Free to start: the first step is never a quote
Security professionals, and entrepreneurs
Behind DomainCheckup is Upstream, a Belgian company that has delivered infrastructure, cloud and security for more than fifteen years. We advise organisations as CISO, we build and run the systems they depend on, and we run businesses ourselves. That combination is deliberate: anyone who runs a company knows an eighty-page report goes unread, and a problem only counts once it is concrete.
An honest grade, in plain language, with what to do about every point. It takes no more than that to make a difference.
The team behind DomainCheckupWhat we stand for
Passive, unless you ask otherwise
We measure what the outside world sees, the way an attacker does, without logging in or changing anything. Active tests only on domains whose ownership you have confirmed.
An honest grade
One serious finding can cap the grade, however many other checks pass. What we cannot measure, we say so, and it costs you no points.
Plain language
Every finding says what it means, what we observed and what you can do, with the standard alongside. Something you can forward without being technical.
