ZyWALL USG clean-traffic architecture
The ZyWALL USG’s clean-traffic architecture
protects against network risks such as viruses,
worms, Trojan Horses, spyware, phishing attacks
and other emerging Internet threats. With the
clean-traffic architecture, enterprises users are
assured to have clean and secure network
environments.
Endpoint security
With the new Endpoint Security (EPS) feature,
administrators can easily identify
policy-violating users such as those who don’t
have AV software installed. With additional AV
software installed, the ZyWALL can help mitigate
virus threats and therefore prevent the loss of
money and employee productivity. The EPS
supports Norton™, Kaspersky™, TrendMicro™
AV client software and many others. Moreover,
the new EPS feature also supports personal
firewall software such as Kaspersky Internet
Security 2009/2010, Windows Firewall and
TrendMicro PC-Cillin/Internet Security 2010.
New generation UTM solution
The ZyWALL USG Series deploys
hardware-acceleration technology in one box.
Powered by high-performance SecuASIC
technology and a hardware-based encryption
accelerator, the ZyWALL USG Series delivers
industry-leading performance and multi-layer
threat protection for small businesses and
enterprises. The ZyWALL USG Series provides
integrated Unified Threat Management security
features such as Anti-Virus (include Kaspersky
Anti-Virus & ZyXEL Anti-Virus), IDP, Anti-Spam,
Content Filtering and Firewall, VPN. All ZyWALL
USG Series products support the Gigabit
Ethernet.
Content Filter stops malware and
Web threats
The ZyWALL USG Content Filter enables
businesses to protect their users and networks
from malware and abuse such as spyware,
phishing attacks and inappropriate P2P or IM
usage. It keeps office computers from getting
infected by dangerous malware and
comprehensively protects business network
environments.
