Agoston, better known as Ago, has been working in the IT industry for 21 years. So long ago that Pegasus Mail was his first mail client - just to be able to use accented characters in mailing lists. He “converted” in 1998 and started using Linux, but remained open to other systems such as Windows and BSD. Because quality work in a large enterprise environment can only be done with knowledge of multiple systems he is constantly training himself in Linux, Windows, networking and new technologies as well. Education has always been a matter of the heart so he helds IT training since 2000. Since then, he has been teaching continuously, not only in Hungary but also in many European countries. Training topics are Linux and network security, ethical hacking, DevOps and automation.
