Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.
Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

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

"One of the valuable features is a standardized OS."
"I like Fortinet's cloud management, as it allows me to manage all my devices in different branches for three cloud accounts, and even though I use on-prem devices, I can manage everything on the cloud."
"The simplicity of the product is great. It's very easy to use, which is a compliment we get all the time in terms of feedback."
"When you start looking at the cost of the license for all the things that you get, Fortinet is by far the best option."
"The main value comes from the simplicity of the product in terms of configuring and managing."
"Fortinet FortiGate is user-friendly and affordable."
"We are using this solution to filter communication to and from the website or our site, and we also use it to create a VPN connection for all of our sites in the world."
"The interface and other reports are all user-friendly."
"WatchGuard Threat Detection and Response is a reliable solution."
"Among the most valuable features is the ease of use — love the interface — of both the web interface and of the WatchGuard System Manager."
"Cloud integration is one of the best features."
"WatchGuard Firebox simplifies my job through the policies we can define, and when we create a policy, it simplifies our workflow, which helps with our overall efficiency."
"This product offers great protection using the default settings."
"The solution is very easy to use."
"The throughput is great. It's perfect. We have no issues whatsoever. The management features are very powerful..."
"My favorite aspect is that its security capabilities are very good, with all-in-one security service capabilities including Intrusion Prevention System, IPS, Gateway Antivirus, Application Control, and Web Filtering."
"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."
"The cost is very low."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
 

Cons

"We'd like to have multi-factor authentication via fiber."
"The security features could have been more similar to those in the Palo Alto firewall with major data protections and WildFire, and deeper inspection capabilities, which Fortinet FortiGate lacks."
"From a pricing perspective, I would rate them a six."
"Fortigate's hardware capacities could be improved."
"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."
"The solution is expensive."
"The main area needing improvement is the user-friendliness of FortiGate's integration with other Fortinet tools like FortiAuthenticator and VPN services."
"To stay ahead of the competition Fortinet FortiGate IPS needs to think about how to adjust pricing."
"There is a problem with the RAM - it's eating up resources. The RAM utilization sometimes reaches up to 80% - 95%, and what we do is just restart the firewall."
"Cloud-based central administration of all devices from one point would be nice (although there is always an added risk regarding this)."
"The solution isn't what I would consider feature-rich."
"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."
"The data loss protection works well, but it could be easier to configure. The complexity of data loss protection makes it a more difficult feature to fully leverage. Better integration with third-party, two-factor authentication would be advantageous."
"The solution's pricing could be improved."
"There should be more reports available on different subjects."
"I'd like a few extra features, especially around threat severity assessment."
"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 product has some scalability and data management issues where improvements are required."
"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."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate could improve, it is expensive."
"The pricing is reasonable."
"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."
"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."
"We pay about $4,000 for a yearly license, and there aren't any additional fees."
"Its pricing is good. It's average or normal as compared to Palo Alto and Check Point firewalls."
"There is a license to use Fortinet FortiGate."
"The price of Fortinet FortiGate is the lowest in the market."
"We license the WatchGuard Firebox annually. There are different types of subscriptions available. We are paying approximately $15,000 annually. The cost can increase if you purchase different subscriptions."
"Over the years, the costs have increased, especially since I cater to very small businesses."
"The price is very good."
"We don't have any other costs other than the licensing stuff."
"The primary reason that we went with Firebox was its cost. It is very economical and it provided us with all the security functions that we were looking for at the time. And the throughput was more than what we required, so it was a very cost-effective device to deploy on our network."
"The price of the solution is not expensive, it is less than FortiGate."
"It's fair pricing, but it could always be reduced."
"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."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
