Department Manager, Remote Access
CurrentThe purpose of 'Remote Access' is to ensure that services for business needs in the Danish financial sector can be accessed in a secure, authorized, compliant and user-friendly way across managed and unmanaged devices and physical locations.
Head Of Department, Collaboration & Remote Access
The purpose of 'Collaboration & Remote Access' is to ensure modern collaboration services for business needs in the Danish financial sector accessed in a secure, authorized, compliant and user-friendly way across managed and unmanaged devices and physical locations.Throughout the COVID-19 pandemic we experienced and handled a very large growth in demand for the department's services. The department handled an increase in video demand by +900% (despite a simultaneous implementation of Microsoft Teams), an increase in telephony consumption internally by 385% and an increase in VPN capacity for JN Data and all our customers by +600% in order to support users working from external locations – all with an exceptional level of operational stability. Likewise, the demand for new and future services also increased extraordinarily. The extraordinary increase in demand, as well as the expected retention of demand, for existing services within ‘Collaboration & Remote Access’ combined with an increased demand for new security services and a shift to a strategic focus on future cloud services saw the department more that double in staffing within a little over a year. To push all different services forwards within the needed timeframes we decided to divide the department into two separate entities.#Microsoft365, #MicrosoftTeams, #VPN, #2factorauthentication, #ApplicationFirewall, #Mail, #SharePoint, #Telephony, #SkypeforBusiness, #Videoconferencesystems
