We are a small team of senior engineers. We build software and audit critical systems. We focus on work where deep technical expertise matters.
Based in Hungary, working with clients worldwide.
We create and launch products end to end—from product design and engineering through infrastructure, deployment and release. A selection of products we have built is shown below, spanning AI-powered video platforms, native software and a published 3D game.

Try it yourselfWe audit applications, infrastructure and systems. Our work includes penetration testing, source-code review, reverse engineering and security assessments of highly sensitive environments. We also help teams remediate findings and harden the systems we assess. A selection of our security engagements is outlined below.
We assessed around fifty mission-critical systems operated by MAVIR, Hungary’s transmission system operator. The engagement spanned Linux, Unix, Windows and mainframe platforms, as well as SCADA environments supporting the continuous operation of critical national energy infrastructure.
mavir.huAcross multiple engagements over several years, we assessed critical applications and core enterprise systems operated by Hungarian Post. The scope spanned Linux, Windows and IBM mainframe platforms, together with nationally deployed iOS and Android applications, and included penetration testing, source-code review, reverse engineering and protocol analysis.
posta.huWe reviewed the company’s live IT environment, combining technical assessment with consultations and stakeholder interviews. The resulting report consolidated the findings into a clear view of the environment and its security posture.
engie.comWe have also undertaken assignments in data protection, security awareness, open-source intelligence and other technical areas within sensitive, high-trust environments, where sound technical judgment, direct accountability and discretion are especially important. Given the nature of these assignments, we mention them here only in general terms.
We supported a system migration and handled the technical tasks arising throughout the transition.
