Vasu Gala - PeerSpot reviewer
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.

Simplifies the management of complex data networks, but its technical support could be improved
Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services. The solution can adapt some of the tools where we, as network engineers, can adjust to the changing application needs. Also, the solution can provide us with multiple support, allowing us to create a network segment. The solution’s technical support could be improved.
Akram Zaki Hussein - PeerSpot reviewer
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 payment function for applications is good."
"Their web interface to manage it is excellent, even compared with other providers."
"FortiGate firewalls are user-friendly, and I like the security profiling features."
"The most valuable feature of Fortinet FortiGate is URL filtering."
"SSL-VPN is very useful for us and has been very reliable."
"They are very affordable compared to Palo Alto and other vendors, offering a great solution for networking and SD-WAN with extremely good protection."
"The solution can scale well."
"A strong point of FortiGate is that the graphical interface is complete and easy to use, especially if we think there is a list of operations that we are able to perform inside."
"It is a stable solution."
"The solution's outcome is very high, and we often use it in a very high-traffic environment."
"GajShield has improved our mobile device-based connectivity."
"GajShield Next Generation Firewall's best feature is the network DLP."
"Gajshiled's enterprise cloud and DLP-level features give it an advantage over other products."
"The most valuable feature of the GajShield Next Generation Firewall is the user-friendly settings, dashboards, and anti-threat protection. Additionally, the solution upgrades frequently which is good because we receive new features."
"It is an easily scalable solution...The initial setup was very easy."
"The most valuable features in OPNsense are reporting and visibility."
"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."
"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"We have found pretty much all the features of the solution to be valuable."
"OPNsense is very stable, easy to upgrade, and maintain."
"OPNsense is easy to scale when running on the hardware."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
 

Cons

"The issue lies with features available in GUI versus CLI during configuration. When using GUI, I want to accomplish everything there, but sometimes it requires using CLI to ensure proper configuration."
"I would like to see improvements in the support from Fortinet. Here in the Philippines, whenever we have problems with a Fortinet product, we mostly ask for support from distributors and resellers and not directly from Fortinet."
"It claims it does DLP, but the degree and level of controls are very basic."
"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."
"Its reporting capabilities can be improved. It should have some out-of-the-box reporting capabilities and some degree of customization. The basic reporting that it currently has is not sufficient to create more usable reports. It needs some sort of out-of-the-box reporting. They try to make customers purchase FortiAnalyzer for this kind of reporting, which is an additional cost. Other firewall vendors, such as SonicWall and Sophos, provide this sort of reporting without any additional cost."
"The user interface of the Fortinet FortiGate management console could be more intuitive and user-friendly, and the log analysis and reporting features could be enhanced to provide more flexibility and customizable insights."
"Backup can be improved."
"I would like reporting to be improved and should offer a lot more tools to monitor the products."
"We raised a support ticket, and the project didn't get a proper response. There was a skill issue in TAC support."
"GajShield Next Generation Firewall could improve the flow of the settings. If somebody's using a Cisco firewall or any other brand and they want to use GajShield Next Generation Firewall the platform's UI is a bit different. If it was more similar to the others it would be better."
"Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services."
"We face issues with some configuration parts that we don't understand in the solution, and sometimes we face issues with the VPN connection."
"GajShield Next Generation Firewall would be improved with the addition of a load-balancing feature."
"The firewall configuration and administration screens could use some improvement."
"Gajshield can improve SD-WAN compatibility at an enterprise cloud level."
"The interface of the solution is an area with shortcomings."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"There are some add-ons that need enhancements to make management easier for users, especially the reporting features. Some reports don't show the level of detail I'm looking for, and I've had trouble installing certain add-ons, especially for Internet bandwidth shaping within my company."
"The scalability needs improvement."
"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."
"I would like better documentation concerning the provided packages and their integration."
"Its interface should be a little bit better."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
