Security is the foundation of trust.
There's one person behind Zelor, someone who has worked as an ISO 27001 Lead Auditor and ethical hacker, and for whom security isn't just a job, it's a passion. You always talk directly with the person doing the work.
With a developer's background, we know how systems are really built, so our advice works in practice, not just on paper. And you get clear reports, in both Hungarian and English.

Security without an expert, made simple
Our upcoming SaaS product helps solo service providers keep their security and compliance in order, and prove it to clients.
Are we a good fit?
Let's be honest: we're not for everyone. Have a look before you reach out, it's better for both of us.
We're a great match if…
- You're an SME, fintech or SaaS and security genuinely matters.
- You're preparing for ISO 27001 or another certification.
- You want a clear, prioritised report, not a 200-page PDF.
- You value talking directly to the person doing the work.
Maybe not right now if…
- You need the cheapest possible tick-box audit, just for the paperwork.
- You want a big, well-known brand name, not a hands-on expert.
- You need everything by tomorrow, with no scoping.
Frequently asked questions
What does Zelor do?
Penetration testing, vulnerability assessment, IT security audit, ISO 27001 lead audit and security-awareness testing.
Who are the services for?
Hungarian and international SMEs, fintech and SaaS companies, and any organisation preparing for certification.
How long does a pentest take?
It depends on scope; a typical web app test takes 1–2 weeks. We give a fixed price after scoping.
Do you work under NDA?
Yes. Every engagement runs under NDA, with strict protection of your data.
Most attacks could have been prevented. That's why I do this: so your systems never end up in the next breach headline. Whatever I find, I explain it in plain language and show you exactly what to do.
