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.

Single-pane management has simplified firewall control and has improved risk mitigation

I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

IT Manager at Zubair Feeds

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

"Overall, this is a very good solution and in fact, a good starting point for a broader cyber security approach for the business."

"FortiGate is easy to configure. We configured one of the units and sent it to Indiana to be installed. We asked them to give us a call when they got it, so we could help them through the process, but they called us back to tell us it works great."

"FortiAnalyzer's capability to provide detailed reporting based on various criteria is highly valuable."

"The interface and other reports are all user-friendly."

More Fortinet FortiGate pros

The architecture makes sense, and the command in the CLI are organized well. They have quite a lot of features are easy to use, and are user-friendly. Any novice can use Fortinet FortiOS without an issue."

"Their classification inside of that database of the various threats is typically very, very good."

"What I like about this solution, is that it is the only solution that currently offers VPN for clients."

"Compared to other firewalls like Palo Alto, FortiOS is easy to deploy and upgrade - for example, an upgrade of Palo Alto takes at least thirty minutes, but Fortigate can be done in around ten."

"Fortinet FortiOS is very easy to use, and when comparing it to other products, its easiness is remarkable."

"The best solution in the category including the price in Thailand is Fortinet FortiOS."

Cons

"The user interface of the Fortinet FortiGate management console could be more intuitive and user-friendly, and the log analysis and reporting features could be enhanced to provide more flexibility and customizable insights."

"The solution needs to improve its integration with cybersecurity."

"The management consoles can be improved."

"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."

"A couple of things I've seen that need improvement, especially in terms of a hard coding. The driver-level active moment really is out-of-the-box and we have to have contact the customer support and sometimes it is difficult to resolve."

"Fortinet FortiGate SWG can be expensive for some customers."

"The renewal price and the availability could be improved."

"At the moment, if you don't integrate any third-party solution with a simple Fortinet FortiGate box, the box would not function as expected for superb protection."

More Fortinet FortiGate cons

"It would be great if they can push the Microsoft updates through Fortinet OS and provide a centralized patch management system. They should also include the data loss prevention (DLP) and data leakage prevention features. They could also add network monitoring more effectively."

"The product needs a feature that allows users to create another site on a VPN."

"I would like to see the features of FortiAnalyzer included in Fortinet FortiOS. Right now, you're required to have an additional license and a different device for features such as processing the log, reporting, and analyzing traffic."

"I would like to see fewer bugs. If you use the box with its basic features, the solution is straightforward and stable, but you can run into bugs when using newer features or in more complex use cases. They included a DNS filter as a new feature, and I had issues that required raising a ticket with customer support."

"There is some room for improvement in the support."

"Right now, it's very trendy to integrate everything into the cloud. This solution would be more effective if they did more integration in that regard."

"Fortinet FortiOS is stable. However, last month we had an issue with a released patch. We had to receive another update to fix the firewall issue consuming all of the resources. The patches should be tested more before going into circulation."

"The reporting for this solution could be improved. It could also be more stable and offer better pricing."

More Fortinet FortiOS cons

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"SSL VPN license cost is not cheap."

"Having frequent live webinars on a monthly basis would really help."

"The current usage reporting is very basic."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"The room for improvement would be the SSL VPN license cost."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"Support from Hillstone E-Series has a shortcoming that needs improvement."

More Hillstone E-Series cons

Pricing and Cost Advice

"It is cheaper and more competitive compared to other options. For example, when comparing Palo Alto products to others, Palo Alto tends to be more expensive. If you compare Cisco's platform, including Cisco Meraki, with Fortinet products, you'll notice that Cisco's offerings are generally higher priced than Fortinet's firewall solutions."

"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."

"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."

"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."

"If you are looking for a quality product, it will come at a higher price. Expecting them to be significantly cheaper is unrealistic. In terms of pricing, it is a bit costly. However, the functionality and support offered are worth it."

"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."

"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."

"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."

More Fortinet FortiGate pricing and cost advice

"Be sure to choose a licensing plan that leaves a little headroom so performance is not an issue."

"The price of Fortinet FortiOS has been reasonable."

"The pricing could always be lower."

"A yearly subscription might be around $20,000 to $30,000."

"It is not cheap; it is also not expensive. It is somewhere in the middle."

"It would be better if it were cheaper. We have the firewall in our office, and the license is expiring in 20 to 25 days. We got a quote for almost 80,000 Pakistani Rupees, which is a little costly."

"It is not cheap."

"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."

More Fortinet FortiOS pricing and cost advice

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"Hillstone's pricing is economical and neither very high nor very low."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."
