Associate Director IT Operations at Procento

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.

More Hillstone E-Series pros

Cons

"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."

"The solution could improve by making the dashboard easier to use."

"There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI."

"There is room for improvement in the reporting part. The reporting is only for logging data, and it's just a tabulation of the log in the report. I would like to be able to take down more information in the event of an incident."

"The pricing of the product is too high. They should work to lower it."

"The support could be improved, Fortinet's response time is very slow. Setting up the VPN could be made much easier, especially when deployed with Azure."

"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's graphic interface could be a bit more responsive and include notations when changes are made."

More Fortinet FortiOS cons

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

"The tool needs to improve its price."

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

"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 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."

"SSL VPN license cost is not cheap."

Pricing and Cost Advice

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

"The price of Fortinet FortiOS is comparable to other similar solutions on the market. We are on an annual license to use the solution."

"The program is expensive."

"The scalability of Fortinet FortiOS is good. However, central management is intuitive for the end-users. We had a lot of questions about central management, and sometimes they didn't use it and did their firewall management directly on FortiGate instead of using Fortinet FortiOS."

"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 price of Fortinet FortiOS has been reasonable."

"The support contracts are usually about $100 - $200 a device."

"A medium 100 or 200 Series box costs around $3000, and the software cost is around 55% of the hardware cost."

More Fortinet FortiOS pricing and cost advice

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

"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."

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

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