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.

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.

Quotes from Members

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

Pros

"The initial setup is straightforward, and it is very customer friendly."
"Firewall and overall management are valuable features."
"This appliance is more secure, reliable, and stable, and we haven't had any problems so far, as for ten to twelve years it has been quite secure."
"We have expanded the wireless access point and switches using Fortinet FortiOS."
"The solution seems very stable once you have everything up and running."
"The most valuable part of the application is the graphic user interface of the application where you can see specifically what's going on in the system at a glance and quickly assess the system."
"I am satisfied with Fortinet FortiOS. It's a cool product and has a lot of UTM features. It has application control, web filtering, antivirus, IPS/IDS, DNS filtering, and many things in that firewall. It also has a web application firewall WAF feature. On the feature side, it's a good firewall."
"You are getting a very good solution with all these features combined into one box."
"Stability-wise, I rate the solution a ten out of ten."
"The installation is easy, we have not had any complaints from our customers."
"Five out of five ROI."
"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients secure connectivity from a remote location to their offices or their servers."
"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."
"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."
"With Hillstone, TCO and ROI are very good, it's an easy sale."
"If an organization is not looking for a web proxy, it's a very, very good product."
 

Cons

"Fortinet FortiOS can improve the monitoring function, it could be more accurate, easy to use, and understandable."
"SD-WAN configuration could be easier."
"Real-time threat monitoring is not there."
"Technical support has issues with knowledge base at the first tier. It sometimes takes hours of explanation before support fully understands and can troubleshoot or escalate problems."
"There are some issues with the performance. We also had some issues while updating the firmware."
"The support is not very good, but the product is stable so it is not so much of a problem."
"The solution could improve the log retention and reports."
"In the future I would like to see more user-friendly dashboards and a drop in the price."
"The tool only had some memory-related problems."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"Having frequent live webinars on a monthly basis would really help."
"The current usage reporting is very basic. I would like to be able to access more granular data."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"SSL VPN license cost is not cheap."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
 

Pricing and Cost Advice

"The price of Fortinet FortiOS has been reasonable."
"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 support contracts are usually about $100 - $200 a device."
"FortiOS is affordable, but its price could be lower."
"There is a license required for the solution and the price is fair."
"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."
"The price of Fortinet FortiOS is less than $10,000 annually. The price of the support is reasonable compared to competitors."
"A medium 100 or 200 Series box costs around $3000, and the software cost is around 55% of the hardware cost."
"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."
"Hillstone's pricing is economical and neither very high nor very low."
"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."
