1.2 ZyWALL UTM Overview
ZyWALL UTM - The Next Generation Firewall
Gone are the days when a dedicated firewall is sufficient to fend off hackers from corporate networks,
Unified Threat Management (UTM) is an emerging trend in the network security appliance market.
This evolution introduces a new all-in-one network security device that provides content filtering, antivirus, anti-spam and intrusion detection services traditionally handled by multiple systems.
In an increasingly complex network environment, it is without doubt that an integrated UTM device
provides streamlined management efforts and ease-of-installation while allowing you to enjoy
multiple layers of network protection.
According to a research conducted by IDC in 2004, the market share of UTM has been growing steadily
from 6.6% in 2003 and is expected to surpass traditional firewall in 2008. "Over the next five years, the
sale of UTM appliances will exceed that of standard Firewall/VPN Internet security appliances," claimed
IDC in the report.
ZyWALL UTM Series - Powered by ZyNOS 4
TM
ZyWALL, ZyXEL's UTM product series with latest ZyNOS 4 operating system, has already addressed
security, feature integration, performance and other issues before you notice them.
Much more than just a simple Firewall, the ZyWALL UTM Series combine not just one or two, but eight
features in a box. Aside from the aforementioned firewall (FW), content filtering (CF), anti-virus (AV),
anti-spam (AS) and intrusion detection and prevention (IDP), the ZyWALL also supports virtual private
network (VPN), load balancing (LB) and bandwidth management (BWM) features normally unseen on
other products in its class.
Thanks to its cutting-edge design, the ZyWALL can still maintain impressive speed without being
bogged down by tremendous loads, even with all eight functions activated at the same time.
Well-rounded features, speed, powerful protection and ease-of-use really make ZyWALL differentiated
and competitive.

1.2 ZyWALL UTM Overview
ZyWALL UTM Advantages
High-Performance 8-in-1 UTM Solution
The traditional way of installing multiple dedicated security devices for network protection is no
longer practical in today's complex network infrastructure and size. Although with multiple dedicated
security appliances, you may pay a small price and quick fix to your problem in a short time. Still, you
are faced with complicated compatibility issues with devices from various vendors and growing
management blues.

This quick response allows the ZyWALL UTM's integrated anti-virus feature to react to new threats as
fast as possible, reducing the risk of massive network infection.
#1 Update Frequency:
Anti-virus software is as good as its latest update. No matter how powerful an anti-virus solution is,
frequent updates of signature files are required to keep up with the pace of new viruses and their
mutations.
Like Detection Rate and Response Time mentioned before, Kaspersky Lab leads the industry again
with the frequency of anti-virus updates. As researched by AV-Test.org Research Group, Magdeburg
University, the number of Kaspersky anti-virus definition updates from January 1 to January 31, 2005
(excluding corrupted, incomplete, duplicate and Beta updates) was a stunning 573, nearly 100 times
more than Symantec Anti-Virus.
It's clear that new updates help the system to block attacks and infections effectively, making realworld performance as good as advertised.
World's First Anti-Virus / IDP Turbo Card
ZyXEL SecuASICTM is the cutting-edge chipset that uses DFA and CPI technologies to greatly enhance
performance. It has been designed to solve well-known performance issues that could render a UTM
device useless.
For instance, a Layer 2/3/4 lookup such as switching, routing or even load balancing takes as little as 50
instructions for a 1500-byte packet; however, a Layer 7 lookup like intrusion detection or virus
scanning may need a whopping 45,000 instructions for the same packet, requiring 900 times more
computing power than simpler tasks.
To address this problem, ZyXEL developed SecuASICTM, an ASIC (Application Specific Integrated Circuit)
solution specifically for enhanced UTM performance. This proved to be a quantum leap over other
similar solutions.
Combining robust Anti-Virus and IDP capabilities through real-time content inspection, ZyXEL
SecuASICTM provides unmatched protection against network security threats.
Despite the fact that Layer 7 lookups will definitely cause performance dragredation,every firewall
vendor is scrambling to upgrade the Layer 7 performance with traditional String-Matching and Packet
Re-assembly techniques. However, even with these, their devices just can't perform well when facing
new threats.
With SecuASICTM, Layer 7 tasks are 20 times faster than "ASIC-less" devices. This dramatically improves
performance and eliminates bottleneck on the network. Compared with other ASIC solutions,
SecuASICTM still have a 5-times-the-speed advantage over the other, older designs.
For more information on the SecuASICTM technology, please refer to the SecuASICTM White Paper.
