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.

"The user interface is easy to use."

"I find Fortinet to be on the higher end of the scale in terms of technical support."

"All networks are security-driven, we get throughputs and security. We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding."

More Hillstone E-Series pros

Cons

"In some specific products, Fortinet FortiOS faces memory issues, which can lead to unexpected downtimes."

"Fortinet's central management needs to be improved. FortiManager's technical tool provider ability should manage all Fortinet security products. Right now, FortiManager only manages the configuration of FortiGate."

"Having used the FortiOS for a period, the improvement of functions and additions have been both "Great" and "Poor," as one gets used to using a product, menu and layout changes can be a bit confusing at first, however you slowly start to get more familiar over time."

"The signature discs, compared to Palo Alto, aren't as good. It takes more time to get the signature updates."

"Fortinet FortiOS need to manage its memory and CPU utilization better. It peaks at times, which sometimes can be challenging."

"The solution's firmware updates have significant bugs and issues."

"Technical support could be better. Some competitors have much more responsive support teams."

"It could more scalable for the lower end users."

More Fortinet FortiOS cons

"The tool needs to improve its price."

"The tool only had some memory-related problems."

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

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The current usage reporting is very basic. I would like to be able to access more granular data."

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

"SSL VPN license cost is not cheap."

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

More Hillstone E-Series cons

Pricing and Cost Advice

"We pay $100,000. That covers the cost of the hardware that we run the VN's on. That also includes any SGNA costs for the internal support tech."

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

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

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

"The cost is around $40,000."

"The software costs roughly half what the hardware costs. Overall, the product is expensive."

"The price of Fortinet FortiOS is less than $10,000 annually. The price of the support is reasonable compared to competitors."

"Pricing depends on implementation and licensing choices and is usually not a practical budget choice for small businesses."

More Fortinet FortiOS pricing and cost advice

"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."

"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."
