SSL-VPN

SSL VPN has rapidly become the preferred technology for remote access users.
This is due to the fact, that while IPSec is an excellent alternative for network-to-network connections, SSL VPN has the following features which make it more suitable for remote access:

• Security
  The SSL VPN appliance allows authorized users to access predefined applications only. These access rules can be set on user or group level.
• Productivity
  Sitting behind a customer's or partners firewall can make life difficult for an IPSec VPN user. If stuck, the firewall administrator needs to open up the required port for your communication, and that is not done easily. SSL VPN overcomes this by communicating using SSL over the normal HTTPS port (443), which usually is open and unrestricted.
  
  Another productivity point is that you can access your applications from any device, i.e. you do not have to carry your laptop everywhere to use your applications.
• Economy
  The TCO for an SSL VPN solution is excellent since many applications can be reached without the need for a client, therefore avoiding deployment and support costs.
