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 reports are detailed."
"The initial setup was straightforward and, because we only need intrusion detection and prevention, we needed only about four hours to deploy it."
"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."
"From a pure cost standpoint, we cut our fees in half by moving to WatchGuard."
"It also provides us with layered security. It has onboard virus scanning features that allow it to scan before something gets to the host. It will also stop a person from going to a site that is known to be bad."
"My advice for people that wants to implement the solution is that it is very good, you get value for money, and you will be well protected."
"WatchGuard has a very easy VPN and branch office VPN setup, so we use those pretty extensively."
"The most valuables feature of WatchGuard Firebox are the VPNs, and web filtering where we can stop users from going to malicious sites."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The cost is very low."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
 

Cons

"The software in it could be a bit more friendly for an amateur user. I look at it and don't understand what half the stuff is. Looking at the interface, it is all mumbo-jumbo to me. It's not a simple interface. You have to be an IT guy to understand it. It is not for your average person to use, then walk away from it. It is much more entailed."
"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."
"This solution needs the option to add an external hard drive."
"In general, I would rate WatchGuard Firebox around 6-7; it is a good firewall, but they lack good administration tools. We experience many problems with the performance and administration tools on the web, including several issues with VPNs."
"The interface is not the best."
"We would like to see granular notification settings and more advanced filtering in traffic monitoring."
"I believe there is room for improvement in policies, with the potential to enhance the margins further."
"I'm not really impressed with the reporting side of it. It may be something I just haven't figured out very well, but it's hard to filter down on reporting of the actual valuable information that you would want. There is a lot of information out there so you have to have some kind of tool capture it and then filter through. So far, I haven't found the reporting side of the WatchGuard to be that user-friendly."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Sometimes it reboots when you least expect it, and that's the main issue."
"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."
 

Pricing and Cost Advice

"The price of the solution is not expensive, it is less than FortiGate."
"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 contract we have is on a three-year basis. There aren't any costs in addition to the standard licensing fees—usually, every three years, we just purchase or renew the same license and we are okay. Every six years, we completely change the firewall, but that's the usual schema. So after three years, we just renew the licenses for another three years, and then after that particular period of time, we just purchase another firewall equivalent to the ones that we currently use."
"For what we use, the tool's price has been reasonable, but it is not the cheapest. The tool has been quite reasonable."
"The cost three years ago was about $800."
"We paid $4000 in AUD for WatchGuard Firebox per year. There were no additional costs."
"It is an entry-level product, so the price is cheap."
"The pricing of WatchGuard is probably a little higher than the SonicWall, but it makes up for it in dependability. It's worth it to me, especially since it's not much higher. For just a little bit higher price you get the dependability of the firewall with the WatchGuard brand."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
