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.

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

"Fortinet offers comprehensive security solutions for various purposes."
"The most valuable feature of Fortinet FortiGate is security. They are known for efficiency and are on the top of Gartner Quadrant reviews. Fortinet FortiGate has an easy-to-use platform with a good graphical interface. The configuration is simple and the solution provides an overall good layer of security."
"Since deploying FortiGate 3401E clusters, we have observed: Dramatic Reduction in Risk Exposure—blocked peer-to-peer and unauthorized applications (e.g., BitTorrent) at the perimeter and east-west segments, eliminating a major source of malware and bandwidth abuse."
"Fortinet FortiGate is one of the best firewalls in the market currently, with a lot of next generation firewall features embedded into it, including SD WAN, which is one of the best services for traffic steering, managing packet log jitter and latency for any applications, making it unbeatable in terms of pricing compared to other firewalls."
"We have used multiple WAN ASPs and set up SD-WAN; it's quite interesting and user-friendly; essentially, anyone can configure it—just go through the documentation and you'll be able to set it up directly."
"Reliability and performance, those are key factors."
"We are very well satisfied with the Fortinet technical support."
"The solution’s initial setup is very easy."
"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 most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
"The cost is very low."
 

Cons

"Application management can be improved."
"Fortinet FortiGate can be integrated with different platforms. They have integrations in place, but I can't say they're 100%."
"One area for improvement is the IPS engine."
"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."
"I would rate Fortinet support a six out of ten. The immediate response is not that good, particularly when raising a critical or P1 ticket; they lag in the immediate response."
"The people we are working with are not able to configure MFA. They are having some technical issues. Fortinet needs to ensure that its partners are well-trained."
"One area for improvement is the performance on bandwidth demands for smaller devices, as well as better web filtering."
"Lacks training for new features."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"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."
 

Pricing and Cost Advice

"There is a license to use Fortinet FortiGate."
"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."
"Pricing is lower than Cisco."
"It cost us around $73,000 for three years."
"If we have an older version, the support costs get quite high."
"When you look at these end security systems and firewalls, these firewalls even five years ago were $50,000 or perhaps $25,000 to implement in some types of customer sites. Now we're talking about tools that are $1,000. In this case, it might have been $500 or something like that."
"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."
"It's expensive, but compared to the competition it's okay."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
