Powerful real-time protection for your business internet.

Business security

As internet becomes a complete necessity, both in the consumer and business worlds, facing network security threats becomes an ever-increasing reality.

And the security breaches have now evolved into highly sophisticated attacks designed to paralyse networks and steal sensitive information. In response to these attacks small businesses now have to meet the great challenge of protecting their networks even more robustly.

The technical bit...

The ZyXEL USG 20/20W/50/100/100-PLUS/200 Series is designed for small businesses to provide real-time inspection and multi-layer network protection to prevent the network from threats. The USG Series embodies Stateful Packet Inspection (SPI) Firewall, Anti-Virus (AV), Intrusion Detection and Prevention (IDP), Content Filtering, Anti-Spam and VPN (IPSec/SSL/L2TP) features in one box.

In addition, the USG Series not only offers complete security license to fulfil your demand but also guarantees the continuous firmware upgrades to save your cost. Incorporating comprehensive security features in the connected devices, the USG Series safeguards your organisation’s customer and company records, intellectual properties as well as critical resources from both external and internal threats.

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 on 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 all processed at higher speeds.

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. Its superior capability is in analysing millions of new patterns each day (24x7x365) to block all the associated messages in 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.
