Vasu Gala

Manager, Information Technology Operation/Presales at TechMonarch

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.

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.

Quotes from Members

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

Pros

"The enterprise-level support is excellent, and we receive quick assistance from Fortinet FortiGate."

"The most valuable feature is the interface, which is very user friendly. We are utilizing most of the features, like content filtering. The firewall is powerful."

"We have been able to offer several services to customers in a single box."

"FortiGate is a great solution, although initially, it faced challenges in the Brazilian market due to lower brand recognition than Cisco. However, explaining and demonstrating its product format and offerings has proven easy. The cost-effectiveness and better features of FortiGate have made some clients skeptical. We set up a trial period, and they eventually opted for it. Many clients were convinced it was great after experiencing the solution's capabilities firsthand."

"Consolidated our network environment at all locations, but mainly at our datacenter."

"The most valuable feature of this solution is the analytics."

"Run Script is the best tool to use in Fortinet FortiGate with multiple environments."

"Fortinet FortiGate has a very stable Linux-based operating system that is easy to use."

More Fortinet FortiGate pros

"The SSL VPN is fee for use is most attractive."

"The stability of Fortinet meets our requirements and I'm satisfied with it."

"The most valuable features of Fortinet FortiOS are its simplicity, highly user-centric, and performs well. The line speed and for heavy traffic, is helpful for us."

"The most valuable features are the intrusion prevention system and the anti-virus."

"FortiOS allows us to set up alarms for blocked websites and SSL verifications. When someone tries to access a blocked site, the solution sends a notification to the IT manager's mailbox."

"The fact that is it has a UTM, a Unified Threat Management feature is the most valuable aspect for us. It's an all in one product. It's like our one-stop-shop to the internet."

"For my organization, it has become much easier to scan the firewalls because the solution is more user-friendly than competitors."

"The solution is very user friendly."

More Fortinet FortiOS pros

More Hillstone E-Series pros

Cons

"They could improve the response time and quality of support."

"Bandwidth usage in reporting could be improved for Fortinet FortiGate."

"Usually, we sell the bundle with the UTM or threat management piece with IPS, IDS. Other providers, such as Palo Alto, are ahead in terms of safe functionality. So, for me, delivering truly safe service is probably something that still needs to be improved."

"One drawback of Fortinet FortiGate is that they provide two types of models: one with a hard disk and another without. The model without a hard disk has very low ROM where you can store very few logs, after which you need to upload it to the cloud or purchase a firewall with SSD."

"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."

"We faced difficulties with the configuration because there are many features we could optimize using Fortinet FortiGate, but our reseller didn't have a good understanding of it. So, we just use it on a basic level, not with the best practice for using FortiGate."

"Fortinet FortiGate is a stable solution. However, my issue is the performance only. When I use all the profiles, this affects the performance. From the beginning, I should have had a better sizing of the box."

"The tool is expensive for small businesses, making it an area where the tool can improve the product by making it available at a cheaper rate."

More Fortinet FortiGate cons

"I believe there could be improvements in the Fortinet FortiOS operation system, such as better integration and a more centralized dashboard."

"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."

"Right now, we have to contend with CLI. We'd like it to be easier. We need the features to be in a UI."

"A switch should be introduced."

"I can only compare it with SonicWall, and it is missing many advanced features that SonicWall has."

"Real-time threat monitoring is not there."

"The complexity of the VPNs should be improved."

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

More Fortinet FortiOS cons

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

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

"SSL VPN license cost is not cheap."

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

"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."

"The tool needs to improve its price."

"The current usage reporting is very basic."

More Hillstone E-Series cons

Pricing and Cost Advice

"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."

"Fortinet FortiGate IPS is cheaper than other solutions like Cisco or Check Point."

"The pricing or licensing of Fortinet FortiGate is quite effective as it offers different bundles that aggregate most required features, while also allowing clients the option to select specific components alone."

"There is a license to use Fortinet FortiGate."

"I would rate the pricing a five out of ten"

"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."

"We are on an annual license to use Fortinet FortiGate."

"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."

More Fortinet FortiGate pricing and cost advice

"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 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."

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

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

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

"The pricing is competitive for the medium and high markets but for the small markets it can be expensive."

"The price of Fortinet FortiOS is reasonable and it is paid annually. You are able to select the features that you want."

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

More Fortinet FortiOS pricing and cost advice

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

"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 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."
