Excellent small firewall

on 6/13/2012

I work for a large Fortune 100 company and there I maintain our firewalls. We use firewalls costing tens of thousands of dollars so I am well aware of what is current in an enterprise firewall. While this box does not have the throughput of a large commercial class box, it has all the bells & whistles you could need or want. It is not a novice class device however. You need to really need to know what you are doing and for this box if you do not, you do not want this device. It has features home users would not have a clue about. However if you want an enterprise class firewall at an affordable price, this is it. I have been using it for a week now and for the price, it's the best you can get.

Big Security for Small Businesses -Unified Security Wireless Gateway ZyWALL USG50

The Internet can be a dangerous place. It seems new threats to network security and employee efficiency emerges with each passing day. Malware can incapacitate workstations, and DoS attacks can bring your entire network screeching to a halt. Even applications such as P2P, IM, and Social networks can eat up bandwidth, crippling network speeds and employee productivity.

The ZyWALL USG50 is here to solve those problems.

With the USG50's Multi-layer threat protection, you can rest assured that your network is secure. ZyWALL's Application Patrol gives you detailed control over the applications allowed to run on your network, while the built-in 180Mbps throughput firewall and Kaspersky anti-virus protect your network from malware, DoS attacks, phishing, Trojan horses, and other threats.

Built with powerful Integrated High Performance Security architecture designed for Gigabit connections, a VPN Throughput of 90Mbps, a UTM throughput of 24Mbps, up to 10,000 max sessions and 5 concurrent IPSec VPN tunnels, the USG50 has the power to monitor and protect your network without sacrificing network performance. And with a 5 year, industry-leading hardware warranty, you'll be able to count on your USG50 to watch over your network's safety for a long, long time.

With 4x Gigabit LAN/DMZ and 2x Gigabit WAN interfaces you can load balance and failover multiple ISP links, allowing you to safeguard even the largest high-bandwidth environments.

With the ZyWALL USG50, you can rest easy knowing that your network is safe, secure, and wholly under your control.

  • Network resilience with multiple WANs, 3G cellular support, and device high availability
  • 5-Year industry leading hardware warranty to support ZyXEL's commitment to quality and customer satisfaction

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 USG50, the following costs can be saved:

  • Save on device hardware maintenance fee: ZyXEL provides 5 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
