Enterprise Integration Strategies

the customers’ security policy and respect
their security needs.
 Glowpoint does not manage firewalls
 2 Methods of Integration
 Video DMZ
 Video Transport Server Solution

Enterprise Integration Strategies
• Video DMZ
– creates a common, secure point between Glowpoint and a
private network on a per LAN basis
– gives the flexibility of accessing the video endpoints without
having them reside inside the private network

network

Some words of praise
Network World
“We were impressed with the state of the IP
videoconferencing services industry. The maturity of
Wire One's Glowpoint service was clear in this study; in
the near future, at least, other companies will find it
difficult to match the reliability, efficiency and feature set
that Wire One has developed.”
Christine Perey,
Principal for Network World’s Global
Test Alliance, January, 2002
