msg has over 8,000 employees in 27 countries. The network infrastructure that Thorsten Jelonnek, Lead IT Consultant, Department DNS—Data Center, Network & Security, and his colleagues in the Network and Security department at msg, put in place ensures that employees can work efficiently from anywhere in the world, whether it’s from company headquarters, the Philippines or Canada.
