The SIGMA server is a secure gateway to
the Internet that operates like a one-way valve, providing
your computer systems access to the outside world whilst
preventing unauthorised access to your system from the
Internet. SIGMA provides three services in order to provide
your business with secure, controlled Internet access,
e-mail and corporate strength anti-virus protection.
Internet Access
The SIGMA server enables all computers
on your network to share a single connection to the Internet.
All web pages that are viewed are scanned for harmful code
or viral infections; it protects your users' computers and
and goes a long way to minimising workstation down-time.
The SIGMA system can be configured to filter certain content;
this ensures Internet facilities are not abused and helps
reduce the risk of corporate prosecution from abuse of the
Internet.
E-mail Server
The SIGMA server hosts the company email
and provides a reliable communication system for internal
and Internet mail. The mail server is an electronic post
office and delivers email to the user’s mailbox, which
is automatically downloaded from the Internet. All email
is scanned for virus or malicious code by the SIGMA’s
anti-virus server. By choosing the SIGMA Server, E-mail
communication runs in real time, allowing you to deal with
Internet enquiries as they happen, improving productivity
and your business reputation.
Anti-virus Server
The anti-virus server is critical to
the security of your network and its resources. All computers
on the network communicate with the anti-virus server, which
provides centralised control across the entire network.
Virus definitions are downloaded automatically as they become
available and are distributed to your computers to ensure
the highest level of protection at all times. Automatically
generated e-mail from the anti-virus server alerts you when
known virus or virus-like code is found. In addition to
alerts, the server notifies you when new definitions have
been downloaded, demonstrating that your system is operating
correctly.
