FT. LAUDERDALE, Fla.--(BUSINESS WIRE)--May 18, 2004

Company Introduces Enhanced Firewall/VPN Appliance for Small

Offices and Firewall PCI Cards for Critical Servers to Coincide with

New Branding of Linux-based Security Offerings

CyberGuard Corporation (Nasdaq:CGFW), the technology leader in network security, today announced that its SnapGear by CyberGuard products have been re-branded as the "SG series." The company also announced the general availability of three new SG solutions, the SG300, SG630 and SG635. Together with its FS, KS and SL series appliances, CyberGuard now offers 13 different firewall/VPN solutions that address security requirements from the core to the edge of the enterprise.

"CyberGuard has a reputation for delivering world-class information security solutions," said Pat Clawson, chairman and CEO of CyberGuard. "Large enterprises and governments worldwide depend on our line of SL, KS and FS premium firewall/VPN appliances. As we bring our combined core-to-edge solution to customers around the world, it makes sense to identify our products consistently across the entire product range."

One of the new products announced today - the SG300 - is a firewall/VPN appliance for small offices and teleworkers that offers business-class security, including a powerful stateful-inspection firewall, service-based intrusion detection, and advanced Internet connection sharing features. The firewall is 2X faster and the encryption up to 3X faster than an earlier version of the product. Another feature of the firewall lets users dial in remotely via analog or ISDN modem, which makes it convenient for telecommuters and home businesses.

"Small and mid-sized businesses face many of the same pressures as larger enterprises," stated Mike Wittig, president and chief technology officer for CyberGuard. "The SG300 security appliance brings business-class security to those environments and allows customers to get the most out of their Internet-connected networks so they can stay competitive. This is a clear price to performance winner for small businesses and replicated sites."

Additional features of the SG300 include:

-- A 4-port 10/100 Ethernet switch so a small business can set up

a local area network quickly and easily;

-- Internet connectivity via broadband (ADSL, cable, SHDSL, etc.)

or narrow-band (modem or ISDN) connections with the ability to

failover in seconds if the broadband connection is lost;

-- A fully integrated VPNC-certified virtual private network,

enabling satellite offices to connect securely to an

enterprise network;

-- Support for industry-standard access methods such as IPsec,

PPTP and L2TP, with strong encryption, to ensure product

interoperability.

The company has also begun shipping new versions of its embedded firewall network cards - the SG630 and SG635 - for security across distributed networks. The plug-in cards fit into standard PCI peripheral slots and function as network security processors inside PC desktops and servers. Both cards serve as advanced, self-contained multi-tasking stateful firewall and VPN appliances. The SG635 also provides an intrusion detection system.

"Up to 90 percent of network attacks originate internally," stated Wittig. "Perimeter firewalls are effective in blocking external attacks, but they cannot prevent attacks that are made by disgruntled employees. An effective security policy must include a multi-layered 'defense in depth' strategy. The SG630 and SG635 make this possible because they complement perimeter defenses with 'embedded' firewalls that provide individual protection for every corporate desktop and every Web application server in a data center."

The SG-series is a set of consolidated, feature-rich firewall/VPN appliances that offer flexible network installations targeted to the edge of enterprises, small business offices and replicated sites. The company's Global Command Center product, its next generation central management solution, will include support for the SG-series of security devices soon.
