Senior System Administrator at a consultancy with 51-200 employees
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

"They are very low maintenance, they have a very high rate of my end-user satisfaction, and I am able to provide excellent levels of service to my end-users and my customers."
"It's user-friendly. And if you are using a WatchGuard device and you want to test that side of the software, it's quite easy to get the license to test it."
"Hands down, it's one of the best firewalls I have ever worked with."
"WatchGuard has been mostly cost-effective compared to other firewall systems that are out there, given the power that it has and the ease."
"The manageability in WatchGuard is very easy."
"HostWatch makes it so I can see, in real-time, activity in the event that there is something weird happening on the network. This simplifies my job."
"We had many bottlenecks before deploying WatchGuard Firebox, but when we switched to a higher version of our firewalls, the bottlenecks were solved."
"The alarm system is valuable."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"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."
 

Cons

"Some of the configuration options are somewhat confusing."
"When working with WatchGuard, specifically in configuring Panda Security on the portal for the first time, it was challenging for me."
"There are a couple of things I wished that it would do, but I can't think of those off the top of my head."
"Websense is an application that monitors and filters internet traffic. Websense was derived from WatchGuard. But when you go to WatchGuard to actually implement that particular feature, you have to use some type of additional feature and you have to pay for it, unfortunately. I think it should be free or free in the WatchGuard box itself, as an option. It would be nice if they didn't charge us for that."
"Sometimes I would like to copy a rule set from one box to another box in a direct way. This is a feature that is not present at the moment in WatchGuard."
"The usability could be better, but it is definitely manageable. If we have to go to a backup internet connection, that could be a little bit easier."
"I believe there is a need for additional measures to connect mobile devices securely to the Firebox router."
"WatchGuard Firebox could improve the speed of updates, such as new features or improvements. However, they are frequently improving the solution in many areas, such as geo-locations, definitions, and web blocking."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"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."
"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."
 

Pricing and Cost Advice

"Cheap."
"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 subscription that was purchased is for three years, but it is usually for one year at a time."
"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."
"I would rate the pricing at seven out of ten. As for the licensing costs, we typically have yearly licenses for our clients, but there are no additional costs beyond the standard licensing fees."
"I think the larger firewall packages are much better because a normal firewall is not enough for these times. You need IPS, APT, and all the security features of a firewall that you can buy."
"We license the WatchGuard Firebox annually. There are different types of subscriptions available. We are paying approximately $15,000 annually. The cost can increase if you purchase different subscriptions."
"The price of the WatchGuard Firebox is reasonable."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
