SG Gateway Appliances (SG3xx, SG5xx Series)

Note
The SG gateway appliance range includes models SG300, SG530, SG550, SG560,
SG565, SG570, SG575 and SG580.
The 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 SnapGear unit's masquerading firewall, hosts on your LAN (local area network)
can see and access resources on the Internet, but all outsiders see is the SnapGear
unit's external address.
You may tailor your SnapGear unit 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 SnapGear unit, to further bolster the
security of your local network.
