Note
The CyberGuard SG gateway appliance range includes models SG300, SG530, SG550,
SG560, SG565, SG570, SG575 and SG580.
The CyberGuard SG gateway appliance range provides Internet
security and privacy of communications for small and medium
enterprises, and branch offices. It simply and securely connects
your office to the Internet, and with its robust stateful firewall,
shields your computers from external threats.
With the CyberGuard SG appliance's masquerading firewall, hosts on your LAN (local
area network) can see and access resources on the Internet, but all outsiders see is the
CyberGuard SG appliance's external address.
You may tailor your CyberGuard SG appliance to disallow access from your LAN to
specific Internet sites or categories of content, give priority to specific types of network
traffic, and allow controlled access to your LAN from the outside world. You may also
choose to enable intrusion detection and prevention services on your CyberGuard SG
appliance, to further bolster the security of your local network.
