Purchase remote access server appliances A remote access server appliance is a standalone device that integrates with your network to provide secure remote computer access. Buy remote access server appliances with advanced security and management features.

I recommend:  The PowerElf Internet server appliance allows users to connect through a secure connection using either a point-to-point tunneling protocol (PPTP) or Internet protocol security (IPSec). PowerElf Internet servers also feature website and email hosting. The Cisco Secure Access Control Server (ACS) uses authentication, authorization and accounting (AAA) services to extend security to remote users and devices. The MultiTech ACS is an analog communications server that provides connectivity through integrated modems. The Lantronix ManageLinx vector defined network (VDN) provides encrypted security through firewalls. The Citrix Access Gateway VPN allows administrators to control user and device access and actions.

Use a hosted VPN remote access server If you don't have the staff or budget to purchase and configure your own virtual private network remote access server, a hosted VPN remote access server might be the solution you need.

I recommend:  PositivePRO Network from Positive Networks uses VPN hardware to manage thousands of SSL and IPSec VPN tunnels. GoToServers uses 128 bit SSL encryption and central authentication to manage a virtual VPN that does not require an open port on your server.

Install a firewall solution with remote VPN access server components Purchase remote access server components as part of your firewall. A firewall isn't a true remote access server, but will provide the security that you need when you allow users to connect remotely. A firewall with ports for VPN connections can provide security by securely allowing a VPN client to connect to your network.

I recommend:  The FVS318 ProSafe VPN Firewall from Netgear provides enhanced security and 8 VPN Tunnels. Secure Point firewalls offer complete network security in one appliance, including firewall, VPN remote access server, content filtering and anti-virus.
