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.

We have improved network security with user-friendly controls and high threat intelligence
FortiOS is very user-friendly and easy to configure for L1, L2, and L3 personnel. Its web filtering, application control, and IPS features are very user-friendly, easy to manage, and deploy. The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs. FortiOS allows us to expand the number of users and devices as our network needs grow.

Quotes from Members

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

Pros

"The most valuable features are that it is very simple to configure and to manage."
"The most valuable feature of Fortinet FortiGate is the simple configuration."
"Web filtering and two-factor authentication are great features."
"The most valuable feature is the bundled subscription, which is IPS, TV and web filtering."
"Fortinet FortiGate is easy to use. Anyone can easily maintain it."
"Fortinet FortiGate is scalable for our users. Right now, we have almost 70 users. We do not have any plan to increase our usage of FortiGate. For maintaining the firewall solution, one staff member is enough."
"FortiGate firewalls are easy to manage through a user-friendly web interface. They also have advanced features like DDoS and DLP. However, I wouldn't recommend enabling all of these features on one device because it can cause performance issues."
"The solution provides good threat intelligence feeds."
"Their classification inside of that database of the various threats is typically very, very good."
"This is a user friendly solution and offers comprehensive integrations."
"The most valuable features of Fortinet FortiOS are user-friendliness, ease of use, and threat prevention."
"All of the features in this solution are effective and efficient."
"Performance-wise, I think FortiOS is much better than its Juniper counterpart. Based on our actual experience and performance metrics, FortiOS-based products are much better than Juniper."
"The SSL VPN is fee for use is most attractive."
"It's easy to use."
"I like its configuration and the various functions it offers."
"The app inspection is very helpful for network security."
"The stability of Palo Alto Networks CN-Series is excellent."
 

Cons

"Application management can be improved."
"The configuration part was challenging, especially converting configurations from another OEM to FortiGate."
"I would like Fortinet to add more automation to FortiGate."
"The solution could be more evenly structured."
"The license renewal process, annual renewal price, and the web application firewall features should be improved."
"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."
"In an incident, after a restart, Fortinet FortiGate did not connect to FortiGuard servers. Due to that reason, on the customer end, all websites got blocked."
"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."
"I believe there could be improvements in the Fortinet FortiOS operation system, such as better integration and a more centralized dashboard."
"Fortinet FortiOS can improve the monitoring function, it could be more accurate, easy to use, and understandable."
"Fortinet FortiOS's integration could be improved."
"The main challenge with Fortinet FortiOS is integration with third-party solutions. I don't see any other areas for improvement. Nowadays, all products work well for 50-60 percent of needs. We must only fulfill 60-70 percent of client requirements because they don't use 100 percent of product features. Banks and financial sectors might need more security features. I don't work much in banking, but they often use multiple products for different security layers, not just firewalls. They might use various products or APIs for different purposes. In the end, clients use the products that suit their needs."
"The additional features I would like to see included in the next release is better troubleshooting and reporting."
"The solution's graphic interface could be a bit more responsive and include notations when changes are made."
"There are some features for FortiGate using FortiOS that can only be enabled via a command line. These aren't very advanced features they have been part of FortiOS for quite some time but they still aren't accessible from the graphical user interface. It makes it a little bit harder than it should be for us to manage the solution. That's my main concern with the user interface. Another concern we have is some elements for the user interface, if they're not properly configured, it could lead to hardware and performance degradation."
"The solution needs improvement with DDoS protection."
"I'd like to see more IOPs features."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
 

Pricing and Cost Advice

"Here in Brazil, we're going through difficult economic times and the tax on the dollar is high. All the solutions from minor competitors are growing in the market. The prices have come more competitive."
"It's a very full-featured and it's priced well solution."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"Fortinet FortiGate is reasonably priced."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"Fortinet FortiGate's price can be reduced."
"It's expensive, but compared to the competition it's okay."
"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."
"Pricing for the tool can vary. Sometimes, aggressive pricing is offered at the start, but later, as subscriptions and expansions are needed, the costs can increase, and customers may have to pay whatever is required."
"Pricing depends on implementation and licensing choices and is usually not a practical budget choice for small businesses."
"The solution could have a better licensing model. It's a bit more expensive than other solutions. The annual subscription is very pricy in Fortinet. The cost could be reduced."
"We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future."
"The Fortinet solutions can be a bit expensive."
"The licensing for FortiOS is good, with a security license included when we update the main license."
"The price of Fortinet FortiOS has been reasonable."
"The support contracts are usually about $100 - $200 a device."
