When a wide area network is implemented, security is an essential factor to address.
WAN links can be used to connect your company to the Internet or to a supplier network
which potentially opens your network to abuse.
Firewall technology is regarded as an essential element in todays networks. A firewall
is a device that selectively allows or disallows data to and from a destination
based on the supplied rules. ZDT can help you implement firewall technology
with many of the leading products including the Cisco IOS, TIS Gauntlet,
Zyxel, Sinicwall, ON Guard and
the UNIX based FWTK.
We can also provide custom built proxy servers, implement SSL security on web sites and
secure access to your open hosts with public key technology.
