Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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 solution is very user-friendly."
"The license management is very valuable; you can get a new license each year or enroll every two to four years, get the logs, and receive information on the risk in your network and the entire organization so you can take action on your assets, computers, or devices."
"It has very easy management and an amazing ETM configuration."
"Fortinet FortiGate protects against internet-based threats, both internal and external, and is scalable, stable, easy to use, and easy to install."
"Fortinet FortiGate has positively impacted our organization by preventing hackers from accessing our network."
"Using this product makes the VPN seamless and almost invisible to me in the sense that I don't have to think about it."
"The most valuable features of Fortinet FortiGate are the ease of use and the UI; it has always provided me with what I needed and I have no need for additional costs that other solutions have, such as Sophos."
"When you start looking at the cost of the license for all the things that you get, Fortinet is by far the best option."
"Now, the provisioning goes more toward what types of software are needed, we have it completely unified across locations with a security standard through the WatchGuard systems due to the roles that we've set up for the organization, and productivity, especially within the IT department, has increased due to the time that we used to spend on each machine can now be spent on the network level."
"We have received a good return on investment."
"The set up of the VPN is pretty straightforward. Being able to build VPNs on the fly for certain users, if need be, is also valuable."
"Watchguard Firebox is easy to use and easy to configure."
"Easy to change the model if you need more performance, with good cohesion in the whole lineup of devices."
"It is easy to deploy and use, the best of breed in the UTM firewall concept, creating the best UTM secure platform ever."
"Initial setup is straightforward; they make the integrations simple and easy to understand, and it is fast, only a day or two."
"The analytics are important because if there is an abnormality then it provides that information to us."
"This is a capable appliance and the standard features work well for us."
"The cost is very low."
"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."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
 

Cons

"The anti-malware engine could use an upgrade."
"The technical support that Fortinet provides is not satisfactory. When we call Fortinet technical support, it takes too much time to connect with them."
"There are some complex administration tasks in their administration portal. That needs to be improved."
"The routing capability on the FortiGate devices has room for improvement."
"Its web interface needs to be more stable, and more functional, through the variety of browsers."
"If they could extend their fabric towards other vendor environments for integration, that would be great."
"One area for improvement for Fortinet FortiGate could be the price, as my clients here are small companies, and they might not have the resources or money to always buy a Fortinet FortiGate solution or FortiGate products."
"There is a need for enhancement with the signature management, improving the datasheet numbers, and scalability issues."
"I believe there is room for improvement in policies, with the potential to enhance the margins further."
"There is a slight learning curve."
"Sometimes I would like to copy a rule set from one box to another box in a direct way. This is a feature that is not present at the moment in WatchGuard."
"Generally, it's just a lower-end product. It does the job but doesn't do it very well."
"There were a little bit of problems with the tool's updates, making it an area where improvements are needed."
"Cloud-based central administration of all devices from one point would be nice"
"The pricing of WatchGuard Threat Detection and Response could be improved."
"Due to their lack of investment in marketing, channel development, and certifications, WatchGuard faces challenges in gaining visibility and market share, especially in regions like Pakistan."
"The product has some scalability and data management issues where improvements are required."
"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."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"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."
 

Pricing and Cost Advice

"The pricing is reasonable."
"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."
"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"It is an inexpensive solution."
"For the price, I'd rate it a ten because it's very cost-effective."
"Its pricing is competitive with other solutions."
"The price is high compared to some of the other solutions."
"It has a very good price. It is not the most expensive one, and it is also not the cheapest one. It is just spot-on in terms of price."
"For what we use, the tool's price has been reasonable, but it is not the cheapest. The tool has been quite reasonable."
"The pricing is competitive."
"WatchGuard offers competitive pricing with attractive margins, benefiting both the company and its partners."
"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 cost three years ago was about $800."
"Despite the fact that there is always room for improvement, the current pricing of the solution is still lower compared to its competitors."
"We only license our corporate one and the one we have at our DR site, we don't worry about the branches. It doesn't pay for us to license the ones at the branches. What they charge for what they call basic maintenance is extremely high for those little fireboxes."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
