Executive SummaryUpdated on Aug 5, 2025

WatchGuard Firebox and Zyxel Unified Security Gateway compete in the network security sector. WatchGuard Firebox appears to have the upper hand due to its user-friendly setup, broad feature range, and strong customer support, though both have areas needing improvement.

A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Makes defining policies simpler but lacks performance and modern features

WatchGuard Firebox is only deployed in one location within my customer's organization, and at the other locations, we are using Meraki and FortiGate. We plan to replace WatchGuard Firebox soon. My impression of the spam blocking capabilities of WatchGuard is not very favorable, as I don't think it is very capable. I haven't noticed effective web ratings or IPS signatures, which may be due to managing an older OS; I'm not certain about the performance of the newer versions. I am not aware of whether the transition to faster ports on WatchGuard Firebox supports maintaining productivity levels during peak usage times. Based on my experience, I would rate WatchGuard Firebox as five out of ten overall.

It Manager at Diamond Braces

A robust appliance that is reasonably priced and straightforward to set up

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"The most effective features for threat prevention are the IPS, content filter, and SD-WAN capabilities."

"Fortinet FortiGate is a very good next-generation firewall."

"In terms of cost, features, and security, everything is top-notch."

"The tool's most valuable feature is IPS. In my experience, I haven't encountered any issues with integration. It easily integrates with the FortiGate solution. However, verifying through documentation and assessing their support is necessary."

"It works very well. It has a lot of different functionalities. Its cost is also fine for our customers."

"The IPS and the application control feature are the most valuable."

"The SD-WAN is the most valuable feature."

"Its stability is the most valuable."

More Fortinet FortiGate pros

"Firebox operates effectively in the background, blocking potential threats without a need for constant monitoring."

"The main reason we went with it was the security protocols. They were more robust on this device."

"If there is any conflict, the reporting feature will kick out all types of information, which is great."

"The most important feature of this solution is the SLAs."

"It has everything we need in terms of functionality."

"I find this solution very easy to manage. The web manager and Firebox key features are particularly impressive for cloud applications. That's why I often recommend this solution to our clients. It has good threat management capabilities and works against different types of threats."

"The firewall aspect and the branch office VPNs are the most valuable features... We don't have any issues with it. We don't have to spend a lot of time maintaining it."

"Firebox's best feature is the access portal."

More WatchGuard Firebox pros

"This is a capable appliance and the standard features work well for us."

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

"The solution can scale well."

Cons

"The solution could improve by having some additional features, such as IBS and better cloud administration."

"Backup can be improved."

"The licensing could be improved as it is a little confusing and too granular for Fortinet FortiGate."

"Fortinet FortiGate SWG's SSL offloading features need improvement."

"I would like to see more advanced developments of a wireless controller in the future."

"We are providing VoIP and the IP licensing could improve in Fortinet FortiGate SWG."

"Whitelisting could be better."

"There were situations of availability related to their switching solutions due to box errors."

More Fortinet FortiGate cons

"It would be wonderful if the WatchGuard team develops nice products for threat intelligence."

"I would like to see more tutorials on setting up the Firebox."

"Websense is an application that monitors and filters internet traffic. Websense was derived from WatchGuard. But when you go to WatchGuard to actually implement that particular feature, you have to use some type of additional feature and you have to pay for it, unfortunately. I think it should be free or free in the WatchGuard box itself, as an option. It would be nice if they didn't charge us for that."

"The solution is a bit confusing and there are unusual complications with setup."

"It's sometimes not easy to understand and can require specialist assistance."

"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."

"The product's technical support services need improvement."

"When implementing a rule using a group of IPs, it is not possible to do that directly."

More WatchGuard Firebox cons

"Although manageable, the user interface is a little bit slow and could be improved."

"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 license of Fortinet FortiGate should be reduced."

"It is a cost-effective solution that meets the user's needs."

"The price is relatively expensive compared to other solutions which are providing similar features."

"Its price is normal. If I compare it with other vendors, such as Palo Alto, it's normal. Palo Alto is expensive."

"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."

"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."

"Fortinet FortiGate SWG is an affordable solution."

"The pricing of Fortinet FortiGate is average, not cheap or overly expensive compared to other firewall solutions in the market. It's effective and affordable for customers."

More Fortinet FortiGate pricing and cost advice

"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 price of WatchGuard is very good."

"We paid $4000 in AUD for WatchGuard Firebox per year. There were no additional costs."

"It's fair pricing, but it could always be reduced."

"The pricing is competitive."

"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."

"Cheap."

"The licensing can be a one-time purchase unless you need the extra services for example twenty-four seven support."

More WatchGuard Firebox pricing and cost advice

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
