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
We use Zscaler Cloud IPS for threat protection, full SSL inspection, and data center scalability. It integrates with multiple products, including cloud firewalls, cloud sandboxing, Cloud Security Broker (CSB), and Data Loss Prevention (DLP). It helps us allow or block specific TCP or UDP ports…

Quotes from Members

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

Pros

"WatchGuard does what it says it does; definitely use it if you want to block applications."
"WatchGuard Threat Detection and Response is a reliable solution."
"I recommend WatchGuard Firebox to other users in small companies because it is simple, it is stable, and the costs are good and right."
"The Dimension control, the one-spot reporting and control, has been nice. It's been easy to go in and make sure people are doing what they're supposed to be doing and that only the right stuff is getting in."
"The most valuable feature is the ease of use of the interface."
"WatchGuard Firebox has had a positive impact on my organization because the improvement in security is evident, and economically, it is a product that is at a very good price point, allowing us to easily have remote clients connected via VPN in an extremely easy way with a lightweight client, which has had a very positive impact."
"It protects me against malicious websites, as well as malicious downloads, as a perimeter anti-virus. I've also seen it blocking a lot of pings and different probes."
"The price of the solution is not expensive, it is less than FortiGate."
"The initial setup process is easy."
"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."
"The product's most valuable feature is complete SSL inspection."
"The initial setup is straightforward and easy in comparison with other solutions."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
 

Cons

"The data loss protection works well, but it could be easier to configure."
"While the GUI version we are using is good, it still needs some upgrades compared to leader companies or firewall models like Palo Alto or FortiGate."
"I would like to see more training become available for us."
"I would like to see more tutorials on setting up the Firebox."
"There were a little bit of problems with the tool's updates, making it an area where improvements are needed."
"It's very hard to get information from their website, for exactly what I need to do."
"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."
"I would like to see more simplified management of the firewall... It's a complicated system to use."
"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."
"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."
"We encounter issues sharing IP addresses with other companies using the software."
"When it comes to scalability, the IPsec could be improved."
 

Pricing and Cost Advice

"We don't have any other costs other than the licensing stuff."
"We pay about $3,500 every three years."
"WatchGuard Firebox is a cheap solution."
"It's an affordable tool"
"It is an entry-level product, so the price is cheap."
"WatchGuard had a very competitive price. It was only 10 to 20 percent more than a single instance device but with that extra cost it provided a second load balancing device... unlike other brands whose method of hardware and software licensing would have doubled our cost."
"The price of the WatchGuard Firebox is reasonable."
"I think the tool is quite competitive compared to the other brands."
"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 product is not affordable for small and medium enterprises."
"The software has become more expensive at present."
