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.

Stable product with valuable SSL inspection features

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"In terms of users within the campus, the policy-based usage helps us where we allow something during the daytime, something after school hours, and something during the night."
"In my experience, WatchGuard Firebox offers a good balance between security, performance, and operational simplicity."
"Going with the Firebox is a no-brainer."
"The tool's most valuable feature is the dashboard."
"The most valuable features of this solution are live logging, rule setup and maintenance, and VPN creation."
"The hardware is very, very stable; we've had no hardware defect in the past ten years, and the software is also very stable."
"Cloud integration is one of the best features."
"Firebox operates effectively in the background, blocking potential threats without a need for constant monitoring."
"The initial setup process is easy."
"The product's most valuable feature is complete SSL inspection."
"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
"The initial setup is straightforward and easy in comparison with other solutions."
 

Cons

"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."
"Last year, I had an issue with one of the Fireboxes going down. It was overheated, because my server room became overheated and this fried it."
"I believe there is a need for additional measures to connect mobile devices securely to the Firebox router."
"The support could improve. I had to deal with support to give me new hardware and it took four weeks."
"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."
"It's very hard to get information from their website, for exactly what I need to do."
"The time they take to classify an application once they find that it is unknown can be better."
"Its graphical user interface could be improved because not everybody is technical. There is a lack of knowledge, and they can give some training for this solution."
"When it comes to scalability, the IPsec could be improved."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
"We encounter issues sharing IP addresses with other companies using the software."
"There is always room for improvement."
"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."
 

Pricing and Cost Advice

"We had a trade-in offer at the end of our first three-year term. As a result, we pretty much got a free device by buying the three-year subscription. It was around $3,000 for the three-years."
"WatchGuard Firebox has good quality, but it is expensive."
"We are utilizing an MSP licensing model and are content with the minimal amount spent on the devices rather than committing to long-term licensing."
"The solution's most valuable feature is its pricing."
"It's in the medium range. Its price is pretty good considering the functions and add-ons that are used."
"Despite the fact that there is always room for improvement, the current pricing of the solution is still lower compared to its competitors."
"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."
"The pricing was in line with everyone else; maybe slightly higher."
"Zscaler has so far been solely responsible for all the sales we have done with it, so it would be more suited than us to address any issues concerning the pricing."
"The software has become more expensive at present."
"The product is not affordable for small and medium enterprises."
