FACE-OFF: Is a mobile VPN a better choice than an SSL VPN?

摘要

Mobile workers face unique challenges and need a VPN designed to address them.SSLVPNs work well for remote workers but take a back seat in mobile and wireless environments. Mobile workers use wireless WAN (WWAN), Wi-Fi, Ethernet, DSL or cable connections from a variety of locations. They need a solution proven in environments with multiple networks and coverage, latency and speed issues. These are different challenges than those faced by remote workers who access network resources from a fixed location. An SSLVPN is a comprehensive VPN, including being a mobile VPN. The real choice is whether you should select a proprietary single-application, network layer-only VPN or a flexible, application- and network-layer SSLVPN for mobile users. The flexibility low total cost of ownership (TCO) and reliability of an SSLVPN will trump a proprietary approach every time.
