Vasu Gala - PeerSpot reviewer
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.

Integrates seamlessly and helps with real-time threat response
Since the solution we offered was a complete suite with Fortinet FortiGate-VM, it was easier for them to manage because they have FortiManager as well. The main reason they wanted to position FortiGate in the cloud was so that they could easily deploy through FortiManager. That was the selling point we had for them. Especially for their multiple branches, where they had approximately 60 sites, and some assets were in AWS, it was really a good deployment opportunity. FortiManager and FortiAnalyzer were also part of that solution.
Alexander Azikov - PeerSpot reviewer
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

"I like its ability to prevent external intrusion into our database. It's so fun."
"Web filtering and two-factor authentication are great features."
"It is user friendly, and has all the features you need."
"The solution is very user friendly. The user interface in particular is quite nice."
"The most valuable features of Fortinet FortiGate IPS are the dashboard and reporting which give us very good visibility."
"Fortinet FortiGate has positively impacted my organization, offering ease of management with no network disruptions; it works seamlessly."
"Fortinet FortiGate IPS has an easy-to-use interface and configuration."
"This solution has a unique range of features that are not available with any other product."
"Primarily, the VPN solution is most valuable. It allows you to have more flexibility in terms of what is there on the end-user device, and what is not there. You can check and make sure that they're current. It has more flexibility than just a straight VPN solution. It works really well. It has the features that 99% of people need."
"The product has been very stable, based on my ten to eleven years of experience."
"GitDM, like FortiGate VM, provides similar features to FortiGate appliances or cloud solutions. However, FortiGate VM is more suitable for heavy traffic and inspection compared to GitDM. Unfortunately, FortiGate VM lacks a dedicated SPU for inspection, and all features rely on CPU and RAM."
"This product is affordable and it's a good, high-performance appliance."
"The performance overall is very good."
"We like FortiGate-VM's IPS features and its ability to create multiple virtual firewalls."
"The most valuable features are the IPS and Antivirus."
"It offers the same robust features and functionality in virtual, on-premise, and traditional data center environments."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
 

Cons

"There are too many updates coming for VPN, and the VPN keeps disconnecting frequently, which I find problematic."
"In terms of pricing, Fortinet needs to do more to compete effectively."
"The customization is a little bit difficult."
"NGN, reporting and controls."
"Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem."
"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."
"It should provide better visibility over the network and more information in the form of reports for the end users. Its installation should also be easier."
"From a support perspective, I had more issues that I didn't think the person on my case handled the way I was expecting. We called them for a geolocation issue and we didn't get any proper assistance."
"Improvements are needed for the responsive UI and JIT traffic reporting."
"We have had some stability issues."
"The user interface (UI) and the performance of interface both need improvement."
"In the Philippine market, where cybersecurity is still growing but not yet fully mature, we have many clients who have Fortinet FortiGate-VM or hardware. However, we cannot really position the Fabric if the licenses, renewal parts, or other components have monetary requirements that hinder full utilization."
"There were challenges during setup, and many of them were self-inflicted."
"The previous version 5.6 had integrated features for logging, monitoring, and management. Now, these features require separate products like FortiManager, FortiAnalyzer, and a FortiCloud subscription for reporting."
"The product's initial setup phase is a bit complex."
"Fortinet needs to overhaul its documentation."
"Although manageable, the user interface is a little bit slow and could be improved."
"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."
 

Pricing and Cost Advice

"We pay about $4,000 for a yearly license, and there aren't any additional fees."
"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"I rate the pricing an eight and a half on a scale of one to ten, where one is low, and ten is high."
"FortiGate Next Generation Firewall is an expensive solution with a yearly subscription."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"Fortinet has more device options that are affordable for small businesses than Palo Alto, and its enterprise-level models are also cheaper. Palo Alto also has a separate license for VPN connections and SD-WAN, but FortiGate offers these features standard."
"This solution is very expensive."
"It would be nice to have the ability to extend FortiGuard subscriptions at a reasonable yearly cost versus a bulk three year pricing.​"
"The price of the solution could be less expensive. There are some features that have to be purchased separately that have their own license."
"There are no additional costs beyond the standard fee."
"There are yearly or monthly licenses which you can choose from."
"The license we pay is a yearly fee. I can't say it's very expensive; it is a good price and is highly suitable for our usage."
"We have been waiting a long time for the vendor to give us licenses, it has been five months and we are still waiting. However, the price is reasonable."
"The product’s licensing must be a little cheaper."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
