Employees from the Viking Group asked about the Z1 product, the manufacturer’s support and the company structure before choosing the solution from Zertificon. As long term customers who have been using the Z1 SecureMail Gateway from the very start and without any significant problems, we were able to recommend the product with utmost confidence.

I’m satisfied with the solution. The product is adaptable, it works.[...] We can secure external communications easily with partners who don’t have S/MIME or OpenPGP. That was the primary reason why we chose it and why MorphoSys AG management found it an excellent investment.
