World class technical courses and technology sessions


Why our network on-site trainings receive average scoring of 4.92 in the scale from 1 to 5? Because except we know the technology, we know how to explain it. We are focusing 100% on participants making them understand not only tech but also solution planning in relation to business relevance and networking market products. The important thing is not only what to learn but also why learning this is important!

We specialize in Enterprise Security, LAN and WAN Enterprise connectivity, Data Centers, and Wireless Systems including LTE, LTE-Advanced, LTE-Advanced Pro and 5G. Our trainers are subject matter experts having experience in transitions and transformations projects in large scale global projects. They hold industry certificates like CCSI, CCIE, CCNP, CCDP, FCNSP, ITIL, VCP and more. They are also IEEE members and international conferences speakers.

What Customers Say About Us?

The exercises in which I participated were discussed theoretically, but later also shown in practice  on the devices, which, thanks to the courtesy of the  trainer, we had at our disposal. I would happily take  part in other courses with this trainer and recommend  them to others.
