About AYAsec
We make a tool that shows organizations what they expose to the internet, and whether any of it is weak. This page is about who makes it and why, which is usually what you came here to find out.
Why it works the way it does
One disagreement runs through all of it, and it is the reason the product exists in this shape rather than another.
Most external attack surface tools work out what you own by inference. They read certificate transparency logs, passive DNS and naming patterns, and decide which hosts are probably yours. That finds things nobody remembered, which is genuinely useful. It also puts hosts in your report that were never yours - a shared address range, a similar name, a hosting provider you happen to have in common with somebody else.
We think that trade is worse than it looks. An inventory that is mostly right is a useful discovery feed and a poor inventory, because you cannot defend any single line in it - you cannot say why that host is on the list or who decided it was yours. And the first time an engineer finds somebody else's server in a report, every other finding in it becomes a maybe.
So AYAsec can take the list from the DNS zone you already control, and it will not scan a domain until you have proved that you control it.
That second part constrains us more than it constrains you. It means we cannot show you a scan of your own company before you sign up - no unsolicited report in a cold email, no live demo of your infrastructure on a call. It costs us the easiest sales move in this category. We think a tool that will scan any domain on request is a reconnaissance service rather than a security product, and we would rather give up the demo than argue that distinction away.
The longer version of this argument is in our guide to attack surface management.
Who we are
AYAsec started in 2026 and is based in Bratislava, Slovakia. There are four of us. Between us we come from running infrastructure, from security auditing and from building software, which is roughly the three angles this problem has.
The company is registered in Slovakia as AYAsec s. r. o., the local equivalent of a limited company. There are no investors - it is funded by the people working in it.
We would rather state that than imply something larger. Four people is small, and it is also why the product does one thing rather than six: a team this size can be useful at one job or thin across several, and we picked the first. It is the same reason the list of what AYAsec is not, further down this page, is as long as it is.
It is also why replies here come from a person. At four people there is nobody else they could come from.
Being in the EU is not incidental either. NIS2 and DORA now require European organizations to know and document what they run, and when you are deciding where your scan data goes, it matters whose jurisdiction the vendor sits in. Ours is the same one as most of our customers.
What AYAsec is not
We would rather you find this out here than three weeks in.
It is not an EDR and does not run on endpoints. It is not a WAF or any other inline control - it watches and reports, it does not sit in the traffic path, and it cannot block anything. It does not scan internal networks. It is not a penetration test. And it does not issue compliance attestations, because no scanner can: certification involves an assessor, and evidence from a scan is an input to that, not a substitute for it.
If what you need is one of those, we would rather say so now. Where we do and do not fit against other tools is set out in our comparison of eleven ASM tools, including the section on when we are the wrong answer.

If you are evaluating AYAsec and something on the site is unclear or looks wrong, that is worth an email too. We would rather fix it than have you work around it.
