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 way it saves me time is that there is no maintenance; once we set it up, there's nothing else for us to do on a regular basis."
"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 haven't a problem with anti-virus stability using WatchGuard for over two years."
"I found several features valuable in WatchGuard Application Control such as the HTTP Proxy, DNSWatch, VPN, and HTTPS Content Inspection."
"One of the most valuable features is the Geolocation. Because we aren't a multinational corporation, it allows me to look at things which might be suspicious to make sure that they are legitimate transactions rather than people sniffing around the network."
"I think it is the best solution in the world, judging by its price and quality."
"The initial setup was straightforward and, because we only need intrusion detection and prevention, we needed only about four hours to deploy it."
"The most valuable feature of WatchGuard Firebox is its ease of use."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"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 cost is very low."
"The solution can scale well."
 

Cons

"WatchGuard is not the best. We already knew that, but it comes with most of the features we need."
"The licensing can be a bit expensive."
"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 drawbacks are just sometimes not having the technical information that we need in order to easily make connections with all of our Internet-based clients, but we can put the work in and still get it done."
"This is a great product and offers great protection but they don't hear the customers' needs. They don't make improvements as per the customers' requests."
"The area where I think this product can be improved is the user interface and the reporting. It can be quite difficult to find the correct logs and to actually find out what is going on. The digging can be time-consuming."
"I would like to see more training become available for us."
"The few issues that we have had, such as not knowing where to go, they have been answered quickly."
"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."
"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."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"The subscription that was purchased is for three years, but it is usually for one year at a time."
"The price of WatchGuard Intrusion Prevention Service is pretty reasonable compared to similar solutions."
"Each one, for the primary unit, was $8,600 and the High Availability unit was $2,000. That's with three years of subscription and support and the Total Security Suite."
"Very competitive pricing regarding throughput compared to other alternatives."
"It is an entry-level product, so the price is cheap."
"WatchGuard Firebox has good quality, but it is expensive."
"The licensing costs are comparatively lower than other providers, and I would rate the pricing as five out of five."
"WatchGuard offers competitive pricing with attractive margins, benefiting both the company and its partners."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
