Networking: A Beginner's Guide
This gives rise to the only real drawback to SSL VPNs: They are still fairly expensive
for smaller companies, with the smallest configurations starting at $8,000 to $10,000 to
support up to 100 simultaneous users. Still, even if you need to support only 20 to 30
remote users, you may find this to be a small price to pay to reduce the administrative
burden of a traditional VPN, which is often considerable.
At the time of this writing, there are a number of SSL VPN vendors. The pioneer
in this space is the NetScreen product family from Juniper Networks (which acquired
a product originally launched by a company called Neoteris, which pioneered SSL
VPNs). Another leader is the FirePass line of products from F5 Networks. AEP
Networks, SonicWALL, and Nokia are some other firms that offer SSL VPNs. Since this
product area is evolving rapidly, you should conduct a careful search for products that
meet your needs.
To give you an idea of how an SSL VPN looks to a remote access user, some screens
of a demo version of F5 Network's FirePass 4000 are shown in this section. Figure 10-7
