The role of a Firewall is to keep
out unwanted intruders while a VPN provides
inter-office connectivity and secure controlled access for
staff and business partners.
Firewall
A Firewall has traditionally been the first line of defence
at the point where your private network meets the Internet.
If you are unclear about the role of a Firewall see Why
I need a firewall. With the multi-gigabit throughput capabilities
of the latest ASIC based appliances from vendors like Juniper Networks
it is now possible to position additional Firewalls at the
core of the network. These can be used to protect sensitive
servers, secure wireless networks or manage the relationship
between departmental VLAN's.
X.COMM has partnered with one
of the worlds leading Firewall vendors. The Juniper Networks appliances are powerful, easy to deploy and blisteringly fast.
They range from sub £500 units for home workers, micro
branches and retail outlets through to multi-gigabit systems
for the most demanding core network environments.

Virtual Private Networks
A VPN carries data securely over an insecure network such
as the Internet. It works by tunnelling the data in an encrypted
IPsec or SSL envelope. This protects your data from prying
eyes and makes it just about impossible to tamper with. The
IPsec standard is ideal for site-to-site links and small remote
access deployments while an SSL VPN
is perfect for larger remote access requirements. See VPN
Technology for a backgrounder on VPN and the relative
strengths of each system.
All Juniper Network Firewall
appliances come with a feature rich embedded VPN Gateway
together with IPSec clients for all current Windows platforms. For global roaming users an ideal adjunct to any VPN system
is iPass.
IPass integrates more than 300 provider networks into a single service covering over 40,000 access points today.
