More and more companies are letting staffers work remotely. In fact, the number of U.S. employees who work remotely at least one day per month has increased by nearly 40 percent since 2001, according to a recent study conducted by The Dieringer Research Group. But most of these companies still rely on IP security or Point-to-Point Tunneling VPNs to ensure secure access to internal resources. Sure, these protocols keep out prying eyes, but these setups have some inherent problems: Typically, VPNs struggle with NAT (network address translation) traversal, access control for traffic in the tunnel and client management.
As an alternative, you should consider Secure Sockets Layer VPNs. SSL VPNs eliminate nearly all the problems associated with IPsec and PPTP VPNs. The term SSL VPN is a bit of a misnomer, however. A VPN typically establishes the remote client as a node on the protected network; an SSL VPN extends secure access to protected resources for remote users.
