Excellent product

by A customer on 11/19/2010

This is an excellent product and extremely capable and flexible especially for the price. The interface is very nice and easy to use but does have a considerable amount of functionality so setup can take time depending on your requirements. I have multiple web servers and email behind the firewall and was able to setup all security requirements. Wifi and VPN equally capable and flexible. However, this is not a device for a novice and does require a good level of knowledge in firewalls and networks. Overall, I highly recommend it.

Great Bang for the Buck

by BrianS on 5/22/2011

I purchased this unit after extensive research of routers in the under $500 price range. For solo, home office, or small business, this unit is hard to beat for features and performance. I'm replacing a NetGear FVS 318, which had a maximum WAN to LAN specification of 12.5Mb/s. In actuality, I was getting around 8Mb/s on a 20Mb/s download connection. With the USG20W, I'm now getting the full 20Mb/s download speed. My upload speed also increased by about 15%. This unit has many features of more expensive units like letting you set up wireless connections or individual LAN ports on the unit in different separate virtual LANs. Also has SSL VPN built in so no need to buy VPN software. Tech Support is great. I spoke to live people several times before buying this unit. Extensive documentation. Set up was easy. Good unit for both novices and pros. Firmware seems to get updated regularly. I wish it had more than 4 LAN ports and I would suggest the body of the unit be metal instead of plastic for better heat dispersion (although I don't know if it needs any more) but also to give the unit the heft it deserves for such a quality product.

Big Security for Small Businesses -Unified Security Wireless Gateway ZyWALL USG20W

The USG20W is a powerful firewall and content management system integrated seamlessly with an 802.11b/g/n wireless access point, bringing you a simple, cost-effective solution for managing wireless connectivity.

Going a step above simple URL-blocking, the USG20W brings you web-content filtering powered by Blue Coat. Blue Coat allows you to choose the level of content filtering, giving you complete control over what types of websites that can be accessed on your network.
ZyWALL's Application Patrol gives you detailed control over the applications allowed to run on your network, while the built-in 150Mbps throughput firewall and web-content filtering protect your network from DoS attacks, phishing, and other threats.

Built with powerful Integrated High Performance Security architecture designed for Gigabit connections, a VPN throughput of 75Mbps, up to 6,000 max sessions and 5 concurrent IPSec VPN tunnels, the USG20W has the power to monitor and protect your network without sacrificing network performance.

  • Robust hybrid VPN (IPSec and SSL)
  • Non-stop Internet access with multiple WAN and 3G backups
  • ICSA firewall, IPSec certification
  • Comprehensive report system
  • Anti-spam service
  • Secure Connectivity

    Given the prevalence and importance of information technology (IT) systems today and the nature and scale of both the opportunities and risks associated with significant deployments of new networking technologies, organizations are forced to evaluate solutions to build up a safer infrastructure to secure online transactions, in which involve exchange of valuable information. The infrastructure should be tailored to meet operation requirements for expanding remote sites as well as mobile teleworkers.

    Proactive Protection

    Malicious virus, worm, exploits could cripple corporate networks and halt business transactions. In addition to severe financial loss, you also risk leakage of confidential information.
    As mass-mailing software companies mushroom on the Internet, your network is bombarded with massive amounts of junk mails (spam). Without intelligent detection and proactive blocking, users have to go through the tedious and time-consuming task of sieving through the overflowing mailbox, and such scenario leads to serious productivity loss.

Policy Compliance

With numerous file-sharing (P2P) and Instant Messaging (IM) applications, it is easier for company employees to share files and chat online during work hours. Rapid file sharing not only compromises network safety with the sharing of questionable files containing malicious viruses, but may also violate copyright issues and create legal hassles.

Network Resilience

ISP links broken, hardware and software failure on the gateway, dead VPN tunnels—these are severe challenges IT staff face when designing the network infrastructure. In short, we need to take fault tolerance on the network path into consideration when build up a highly available network infrastructure for non-stop operations.


With Vantage CNM (Centralized Network Management), users can achieve the follow objects:

  • Easy VPN management and diagnostic capability
  • Complete security policies and UTM management
  • Low TCO of massive deployment and device maintenance
  • Active monitoring, alerting and comprehensive graphic reports

The solution provides an efficient centralized management system for enterprises of any size to reduce operational costs regardless of the number of branch offices or remote locations.


With the adoption of ZyXEL's USG 20W, the following costs can be saved:

  • Save on device hardware maintenance fee: ZyXEL provides 2 years hardware warranty out of the factory.
  • Free software upgrade: now ZyXEL provides free software upgrades so you can enjoy complete protection without additional expense
