Benefits:

Robust security without sacrificing performance

The Zyxel USG 20/20W/50/100/100-PLUS/200 Series is built with a powerful Integrated High-Performance Security architecture that provides real-time inspection to prevent networks from threats without sacrificing performance. Corporate networks are not only flawlessly secured but also get significant performance enhancements on productivity and efficiency since file loading, emailing and information searching applications are processed at higher speeds.

Comprehensive IPv6 support smoothly connects future-ready networks

The Zyxel USG Series is IPv6-ready today and is certified with “IPv6 Ready” gold logo. With IPv6 feature enabled, the USG Series ensures businesses with a smooth migration path from the IPv4-based networks to the full IPv6 infrastructure. It assigns IPv6 addresses to clients and passes the IPv6 traffics through the IPv4 environment. The USG Series supports dual-stack and IPv4 tunneling (6rd and 6to4 transition tunnel) implementations for Internet connectivity to access IPv6 applications.

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 Zyxel 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 Zyxel 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 Zyxel 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 Zyxel 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 Zyxel 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.

EASY VPN — zero configuration remote access

When establishing VPN tunnels, it could be quite difficult for non-technical employees to use due to the complicated configuration.

The Zyxel 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.

Content Filter stops malware and Web threats

The Zyxel 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.

Non-stop Internet access with multiple WAN and 3G backups

The Zyxel USG supports not only WAN traffic load balancing to increase the overall network throughput but also flexible 3G backup as a WAN alternative to enhance network reliability.
