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 best feature of Fortinet FortiGate is the IPS or IDS implementation. I appreciate most the agility or the flexibility to create hashes to block incoming threats, and I can integrate with third-party threat intelligence with our FortiGate."
"The user interface (UI) is very, very good."
"It's user-friendly and easy to operate."
"Overall security features and performance routing is good."
"Layer-3 firewall and routing are the most valuable features."
"The most valuable features of Fortinet FortiGate are the ease of use and there are several operating systems that can include the hardware capacities. In the newer releases, the resources were more useful because they were included in the operating system."
"I haven't configured or experienced any stability issues."
"The most valuable features are that it is very simple to configure and to manage."
"Gajshiled's enterprise cloud and DLP-level features give it an advantage over other products."
"GajShield has improved our mobile device-based connectivity."
"It is a stable solution."
"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."
"GajShield Next Generation Firewall's best feature is the network DLP."
"It is an easily scalable solution...The initial setup was very easy."
"The solution's outcome is very high, and we often use it in a very high-traffic environment."
"The initial implementation process is simple."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"The system in general is quite flexible."
"The most valuable features in OPNsense are reporting and visibility."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"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."
"It has an open license. It works very well, and there is an update every month."
"I feel that its valuable features are that it is simple and free."
 

Cons

"If they could extend their fabric towards other vendor environments for integration, that would be great."
"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security."
"The ease of use could be improved."
"There were quite a few problems with the stability of the system."
"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."
"Scalability is one of the disadvantages. When it comes to scalability, you have to actually change the box. If you want to upgrade it, you need to actually change the existing box and probably you take the system off to other sites."
"It does not have key authentication for admin access."
"They could improve the response time and quality of 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."
"The firewall configuration and administration screens could use some improvement."
"Gajshield can improve SD-WAN compatibility at an enterprise cloud level."
"We raised a support ticket, and the project didn't get a proper response. There was a skill issue in TAC support."
"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."
"Its interface should be a little bit better."
"There should be more technical documentation."
"They should improve IPEs for security in the future."
"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."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"The user interface could be improved, and the DNS section should be more intuitive."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"The solution would not be suitable for anything large-scale."
 

Pricing and Cost Advice

"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"If you are looking for a quality product, it will come at a higher price. Expecting them to be significantly cheaper is unrealistic. In terms of pricing, it is a bit costly. However, the functionality and support offered are worth it."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."
"Its pricing is good. It's average or normal as compared to Palo Alto and Check Point firewalls."
"The main reason we chose Fortinet FortiGate was that the price was better than the competition."
"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."
"The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."
"GajShield Next Generation Firewall is reasonably priced."
"GajShield is a cheaper solution as of now. The subscription is yearly."
"It was about 15% cheaper compared to Sophos."
"The price of the GajShield Next Generation Firewall is very attractive when compared to other solutions."
"GajShield Next Generation Firewall is not that expensive, and its pricing is better than Palo Alto."
"GajShield Next Generation Firewall is cheaper than the other products in the market. The licensing costs for the solution are on a yearly basis."
"It is free."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"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."
"We are not paying any licensing fees. OPNsense is completely free for us."
"As an appliance, it's in the medium price range."
"OPNsense is an open-source solution and it is free to use."
