It is the traditional approach for end to end secure connection between the end points, with the high speed and reliable connection. The VPN solution provides the mobile network connected and productive by ensuring security as well as the streamlining management. Mainly the traditional VPN is designed for stationary devices with the strong static connections, then not the constant dead spots. When VPN encounter some issues, their network tunnel gets interrupted which leads to application disconnects or session timeouts. Vpn in mobile environment has the purpose built for mobile IT. It is commonly used for public safety, home care, hospital settings and much more.
