CyberGuard SG PCI Appliances
The CyberGuard SG PCI appliance (SG630, SG635) is a hardware-based firewall and
VPN server embedded in a 10/100 Ethernet PCI network interface card (NIC). It is
installed into the host PC like a regular NIC, providing a transparent firewall to shield the
host PC from malicious Internet traffic, and VPN services to allow secure remote access
to the host PC.
This appliance is recommended for:
•
Security conscious businesses that wish to separate firewall and VPN issues from
server/desktop operating systems.
•
Businesses that wish to eliminate the "soft center".
•
For environments where the integrity of the host server operating environment
cannot be controlled or trusted.
Unlike CyberGuard SG gateway appliances, a single CyberGuard SG PCI appliance it is
not intended as a means for your entire office LAN to be connected to, and shielded from,
the Internet. Installing a CyberGuard SG appliance in each network connected PC gives
it its own independently manageable, enterprise-grade VPN server and firewall, running
in isolation from the host operating system.
