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

"The most valuable feature of WatchGuard Firebox is its ease of use."
"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."
"We have witnessed an ROI as it has helped with security measures."
"Initial setup is straightforward; they make the integrations simple and easy to understand, and it is fast, only a day or two."
"The most valuable feature is the protection that it offers, and the analytics are important because if there is an abnormality then it provides that information to us."
"The features that I have found most valuable are the FireWall features. The management side of WatchGuard is quite easy because it supports two ways to manage it - by the web and the other one they call WatchGuard systems manager. I used to be familiar with WSM only, but they improved their GUI in the web browser and now it is much easier to do it within the web browser."
"The most valuable feature is the NAT-ing, the IP addresses... We can direct the traffic where it needs to go. We can control the traffic."
"The solution is stable; we haven't experienced any bugs or glitches, there haven't been any crashes on it, and our clients seem quite happy with it so far."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
"The cost is very low."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"Cloud-based central administration of all devices from one point would be nice (although there is always an added risk regarding this)."
"It's very difficult to find a reseller of WatchGuard Firebox to purchase a license"
"Make WatchGuard Firebox capable of integrating with third-party vendors like FireMon, Splunk, Tenable, etc."
"There is room for improvement in the threat protection, data packet inspection, and performance of the solution. Generally, it's just a lower-end product. It does the job but doesn't do it very well."
"The UI and web view aren't nice."
"Reporting is something you've got to set up separately. It's one of those things that you've got to put some time into. One of the options is to set up a local report server, which is what I did. It's not great. It's okay... Some of the stuff is a little complicated to get up and running. Once you do, it becomes very user-friendly and easy to work with, but I find there are some implementation headaches with some of their stuff."
"What could use some significant improvement in WatchGuard Firebox would be its interface and policy management."
"The administrative UI/UX could be significantly improved."
"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 product has some scalability and data management issues where improvements are required."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"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

"Its cost is okay. It is not too expensive, not too low. I would rate it a nine out of ten in terms of pricing."
"The pricing was in line with everyone else; maybe slightly higher."
"WatchGuard Data Loss Prevention's pricing is expensive. I rate it a seven out of ten."
"The solution's most valuable feature is its pricing."
"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."
"The solution is a bit more expensive than other options."
"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 price of the WatchGuard Firebox is reasonable."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
