Featured Reviews

Abhishek Saini - PeerSpot reviewer
Professional Services Engineer at Next7 IT
Centralized security management has improved VPN reliability and simplified daily operations
WatchGuard Firebox is a strong and reliable platform overall, but there are a few areas where improvements could make the experience even better. One area is the user interface and navigation in some management tools. While the platform is powerful, certain configurations and troubleshooting workflows can feel less intuitive compared to some newer cloud-native firewall platforms. Another point is reporting and log analysis. Although the logging features are very useful, deeper analytics and more customizable reporting dashboards would make security monitoring much more effective. Firmware upgrades and policy synchronization can sometimes require careful planning to avoid security interruptions. Overall, the core security and VPN functionality are very solid, but improving usability, reporting, and automation would make the platform even stronger. One area that could be improved is the learning curve for new administrators. While experienced engineers can work with the platform effectively, some advanced networking and security configurations can be a bit complex for junior technicians. More guided configuration workflows, smarter recommendations, and simplified troubleshooting tools would make onboarding easier. Another improvement would be more flexible reporting customization for executive-level and client-facing reports.

User has benefited from stable performance and effective completion of security tasks
I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We use the on-premises deployment model. It's a great product."
"The Dimension control, the one-spot reporting and control, has been nice. It's been easy to go in and make sure people are doing what they're supposed to be doing and that only the right stuff is getting in."
"In terms of users within the campus, the policy-based usage helps us where we allow something during the daytime, something after school hours, and something during the night."
"WatchGuard is easy to implement and inexpensive. When we get a bulk-off license, we get a very discounted price that is competitive with alternative or competitor solutions."
"My favorite aspect is that its security capabilities are very good, with all-in-one security service capabilities including Intrusion Prevention System, IPS, Gateway Antivirus, Application Control, and Web Filtering."
"The VPN and the filtering features are the most valuable. Its VPN is very strong, and its services are very nice. The main problem in India is the service. There are not enough Check Point and Fortinet Firewall services, but for this product, the service is very good."
"Among the most valuable features is the ease of use — love the interface — of both the web interface and of the WatchGuard System Manager."
"The most valuable are the VPN and proxy features."
"This is a capable appliance and the standard features work well for us."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The cost is very low."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
 

Cons

"We were able to take from an older configuration, build a new one quickly, and get it up and running, which didn't take long, but there was some pain around it."
"It would be wonderful if the WatchGuard team develops nice products for threat intelligence."
"I haven’t dug deeply into the reporting features yet or if they are working well. However, I have generated several reports and there was too much unnecessary information, in comparison with the reporting features in the Sophos firewall. Sophos' reporting is more readable and easier to configure."
"The performance of the solution's processor needs to be faster."
"The way Secure Sign-On authentication is happening needs to be improved. When the Secure Sign-On portal is turned on, anybody who comes into the campus, whether he or she is a staff member or a guest, has to go past the initial portal. One of the shortcomings is the username. It shouldn't allow permutations or combinations with upper or lower cases. For example, when there is a username abc, it shouldn't allow ABC or Abc. It should not allow the same username, but currently, two separate people can go in. Therefore, its authentication or validation should be improved, and the case sensitiveness should be picked up. If I have restricted someone to two devices, they shouldn't be able to use different combinations of the same username and get into the third or fourth device. It shouldn't allow different combinations of alphabets to be used to log in."
"Reporting is something you've got to set up separately. It's not great. It's okay."
"Websense gives you detailed information as far as the source, but this one only gives you very basic information and, on top of that, it's a free version for only a few months and then you have to pay for it."
"I think one area for improvement in this solution would be enhancing communication with tools like Active Directory. This would make the tool easier to integrate and effective for users."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"Sometimes it reboots when you least expect it, and that's the main issue."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"The cheapest configuration, for maybe five people, is approximately $500."
"I buy a three-year renewal on the main device, which is usually around $3,000 to $4,000. They usually upgrade the device when I do it. You get a big discount when you do three years."
"It's fair pricing, but it could always be reduced."
"I usually tell people that it's really affordable as well, particularly compared to Cisco."
"The solution is cheap."
"The solution is not expensive and customers pay for a yearly license."
"The licensing costs are comparatively lower than other providers, and I would rate the pricing as five out of five."
"I spent $600 or $800 on this product and I'm paying a couple of hundred dollars a year in a subscription service to keep the lights on, on it... It works out to $100 or $200 a year if you buy several years at once. It's fair."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
