Marketable solutions require vision

Operating as one of the leading manufacturers of KVM extenders, switches and matrix switches over many years has enabled us to gain solid knowledge in developing and manufacturing our products. The ways in which our broad product portfolio can be combined even in large and complicated projects never ceases to amaze our customers. Already impressive in their basic version, our product variants are even more versatile when combined together.

“The true magic of our products unfolds when they are combined. Almost any requirement that is physically feasible can be met through numerous permutations and variations.”
– Roland Ollek, Director of Sales & Marketing
