Featured Reviews

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

"Because of the way it's organized and the user-friendliness of the device, it does make my job managing the firewall profiles and security a lot easier."
"Hands down, it's one of the best firewalls I have ever worked with."
"They've done a lot of work with their SD-WAN, which we do use, to have our old internet service with our new internet service. If anything goes down on a particular interface, I can have different rules applied. Most of my users don't even know when our primary internet goes down anymore... I don't have to be here to do anything to switch it to our backup internet or to switch it back."
"I find that their tech support is excellent. And as a reseller, my relationship with my point of contact is also strong. WatchGuard does a good job of maintaining that."
"The policy monitoring and allowing different traffic flows are the most useful features for us; regulating which traffic comes in and out."
"The features of WatchGuard Firebox are most valuable for maintaining network security."
"It keeps our network secure and that's a good enough return for me."
"One of the most valuable features is that when we send emails and it gives a warning, you can configure those email addresses so that they can only send outside the email."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
 

Cons

"There is no message displayed for the user on the desktop informing them that access to a web page has been blocked by Application Control."
"WatchGuard is not the best. We already knew that, but it comes with most of the features we need."
"The interface is not the best."
"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."
"One area for improvement could be making the interface even more user-friendly."
"The solution isn't as efficient as a product like Palo Alto."
"The way Secure Sign-On authentication is happening needs to be improved."
"WatchGuard Data Loss Prevention catches so little. When I've implemented it, it just can't look at the traffic in a thorough enough manner to capture as much as it should. And I find that I'm disenchanted with all data loss protection solutions I've tested and looked at."
"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."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"The product has some scalability and data management issues where improvements are required."
"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."
 

Pricing and Cost Advice

"The solution is a bit more expensive than other options."
"Their price point worked, which is the reason why we stayed with WatchGuard."
"The cost three years ago was about $800."
"The price of WatchGuard is very good."
"The primary reason that we went with Firebox was its cost. It is very economical and it provided us with all the security functions that we were looking for at the time. And the throughput was more than what we required, so it was a very cost-effective device to deploy on our network."
"As per my knowledge, the product is more affordable than alternatives."
"The two larger devices are about $1,000 each and the smaller ones are about $500 or $600 each... It's cheaper and you have more control because it's self-managed."
"The licensing model for WatchGuard Application Control is based on the number of users. WatchGuard Application Control also has licensing models with several features."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
