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.

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.

Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support
The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.

Quotes from Members

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

Pros

"The management console is pretty simple, so anyone who understands networking can initially deploy the solution."
"Its usability is good. We can easily navigate the system, and we have a very good user experience."
"The ease of setting the solution up is a valuable aspect for us."
"It is pretty straightforward to manage and has robust capabilities. I appreciate that Fortinet FortiGate can be a central controller for other Fortinet products, such as switches and access points."
"Security solution with a straightforward and quick setup. It's a stable and scalable product."
"The reporting you receive out of this appliance is excellent. You will not need an external management system."
"Fortinet FortiGate is easy to use. Anyone can easily maintain it."
"Using this product makes the VPN seamless and almost invisible to me in the sense that I don't have to think about it."
"The most valuable feature of the Hillstone E-Series is its user-friendliness."
"The initial setup was straightforward. It only took a few hours to deploy."
"Stability-wise, I rate the solution a ten out of ten."
"Very reliable solution with good scalability and straightforward implementation."
"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."
"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."
"The most valuable feature of the solution is the ransomware protection that the tool offers."
"Five out of five ROI."
"It has an open license. It works very well, and there is an update every month."
"We have found pretty much all the features of the solution to be valuable."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"The initial setup is easy. It only takes 15-30 minutes to deploy."
"The solution is good for a basic firewall for a small business or for home use."
"I feel that its valuable features are that it is simple and free."
"I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed."
"OPNsense is easy to use and open source."
 

Cons

"A lack of integration between our data centers."
"FortiGate can only retain logs for 24 hours or 7 days. I'm not sure if it holds them for a longer period, such as for a month."
"Its filtering is sometimes too precise or strict. We sometimes have to bypass and authorize some of the sites, but they get blocked. We know that they are trusted sites, but they are blocked, and we don't know why."
"With the standard support subscription, if the device goes down, the customer has to first ship the box, and then Fortinet sends the replacement. With the higher support, the customer has to ship the device after they have the replacement. It would be better for customers to get immediate replacements even with a standard subscription."
"We are pretty happy with it. If anything, I believe the web interface could be simpler, especially for someone who has limited networking experience."
"The support is inadequate. The support staff I have dealt with lately are very rude. Some support staff are not up-to-speed with the technology. They basically read a script."
"To the best of my knowledge, Fortinet does not have a CASB solution and Fortinet does not have a Zero trust solution."
"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."
"SSL VPN license cost is not cheap."
"The current usage reporting is very basic."
"Having frequent live webinars on a monthly basis would really help."
"The tool needs to improve its price."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."
"There are issues with stability and reliability."
"I would like better documentation concerning the provided packages and their integration."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"I would like to see better SD-WAN performance."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
 

Pricing and Cost Advice

"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."
"The Fortinet FortiGate security features cost approximately $1,500 a year. The firewall itself doesn't have a recurring cost. It's the security features on top of that that you pay for."
"It's expensive, but compared to the competition it's okay."
"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."
"The price could be lower."
"Go for long term pricing negotiated at the time of purchase."
"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."
"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."
"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."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"I would rate the pricing three out of ten."
"There are no licensing costs for OPNsence."
"It is free."
"As an appliance, it's in the medium price range."
"It's not expensive."
"It costs about $1000."
"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
"OPNsense is open source software so at this time it is free for us to use."
