EASY VPN reduces operation cost and time
Establishing a VPN tunnel is a good way to build secure connections among remote offices, branch offices and partners; however it is difficult for
non-technical employees, such as sales people, to use because of complicated configuration. The ZyWALL USG Series is equipped with the “EASY VPN”
solution to push configuration files to the VPN clients automatically; this eliminates the configuration efforts while securing the access at the same time. In
addition, the USG Series supports L2TP VPN technology on iPhones, Android phones and many other mobile devices as L2TP VPN enables employees in
remote places to connect to the headquarters with easy and free access.
Content filter for safer Web surfing
The World Wide Web has become the main target for network threats, since the Internet itself is a very effective malware delivery mechanism. With threats
hidden directly in contents such as cookies, add-ons and rootkits, it makes malware exceptionally difficult to detect.
The ZyWALL USG Series content filter solution provided by Blue Coat and Commtouch, the leading providers, reduces costs and extends protection by
combining a comprehensive, integrated database featuring millions of URLs, IP addresses and domains. With the solution, the USG Series not only enables
real-time protection that deters emerging Web threats including malware and phishing, but also blocks or monitors certain sites to maintain employee
productivity.
Powerful Email security
The ZyWALL USG Series delivers industry-leading protection, powered by Commtouch, against spam, phishing and virus-laden emails. The extremely high
performance of Commtouch technology comes from the unique recurrent pattern detection (RPD) mechanism that possesses its superior capability
through analyzing millions of new patterns each day (24x7x365) to block all the associated messages real-time. In addition, the ZyWALL USG applies
sender-based IP reputation to remove over 80% of unwanted mails and to take advantage of the zero-hour virus outbreak protection feature, which is
capable of blocking or delaying suspicious messages hours before commercial anti-virus signatures are available.
More 3G card support
The ZyWALL USG Series not only supports multiple WAN ports but also 3G networks through USB or PC cards. With 3G connections, the USG Series enables
load sharing or failover to deliver highly reliable network connectivity; it also supports more 3G cards with generic driver to ensure excellent
interoperability. Since the customers don’t have to purchase specific 3G cards to save cost.
High performance
The ZyXEL USG Series is built with a powerful
Integrated High Performance Security
architecture. It provides real-time inspection to
prevent networks from threats without sacrificing
performance. Take the USG 50 as an example: its
excellent performance delivers sufficient speed
boost to meet all small business needs.
