Our company was established in the middle of 1999 to develop the ALF firewall. Security and reliability were the the two most important goals in the development of the services and systems of the company from the beginning. Our company mainly uses Unix (primarily Linux) systems, we deal with the planning, installation, and maintenance of these. During our operation we learned, applied then integrated in our portfolio the virtualisation, too. Since 2006 we have been cooperating as the VMware Enterprise Partner with audit, training, consulting and operation in this area. We put serious emphasis on the continuous improvement of the skills of our developer, system administrator and expert team, therefore our employees participate in professional trainings on a regular basis. The number of engineers employed is continuously increasing, with minimal fluctuation. Our employees continuously monitor the systems they planned and installed, therefore their operation is smooth. Thanks to the security, remote administration and supplementary technologies we have developed, we operate several hundred systems. The great experience of our engineers is a guarantee of flawless operation of the systems, and the very quick resolution of problems that may incidentally occur.
