Efficient, user-friendly, and affordable

In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Good interface and firewall capabilities and overall easy to use

The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Senior IT Infrastructure Engineer at Khansaheb

Provides effective threat prevention and helps improve security

We face some challenges when we upgrade the solution. If I use NSv 400, I can't upgrade to the next generation. We cannot upgrade the VM to the next generation. We have to rebuild a new VM and copy the configurations. We cannot upgrade straightaway. The solution must allow us to upgrade the same machine to a newer version without many changes.

Quotes from Members

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

Pros

"The product is easy to use and is stable. The SV1 functionality is a benefit."

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

"Fortigate is very scalable to serve our customers' needs. We have scaled already from fifty to more than a hundred instances of Fortinet FortiGate. Around 20 staff are required for deployment and maintenance, mostly engineers."

"Fortinet FortiGate is a security device. It can optimize security on the networks of a company. It actually protects the company from attacks from outside. With FortiGate, you can categorize the users. You can create a group of users that can access all of the websites for their work. You can limit other users' access."

"It is a safe product."

"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 interface is very good."

"UTM/NGFW features and FortiCloud for logs and backups are awesome."

More Fortinet FortiGate pros

"The solution is user-friendly and easy to configure."

"The solution is good for a basic firewall for a small business or for home use."

"The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."

"The most valuable features are reporting, the Sensei plugin, and firewall capabilities."

"The initial implementation process is simple."

"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."

"OPNsense is highly stable."

"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."

More OPNsense pros

"SonicWall excelled in threat management, evident in how users handled it effectively."

"The customization of firewall rules provides great value to our customers as it allows them to lock things up in the way that they desire. When it is used for internal access, with a VPN in place for remote workers, the firewalling services provided by Azure, such as the default services that can be turned on, are applied. However, the use of a software-based virtual firewall gives us greater flexibility in introducing security controls for customers who are publishing applications that are publicly accessible from the public cloud. This virtual firewall provides an additional layer of security and more extensive security control options to ensure the protection of our customers' valuable information and assets."

"One of the standout features of SonicWall is its simplicity in creating and managing rules."

"SonicWall NSV is easy to use, and you can use it to manage the logs easily."

"The security of this system is fantastic, including the IPS and IDS."

"Out of ten, I would rate the solution at an eight."

"I would rate the overall product a nine out of ten."

"We purchased the AGSS Bundle (Advanced Gateway Security Suite) for the security services, such as antivirus, intrusion prevention system, and anti-spyware botnet GUI."

More SonicWall NSv pros

Cons

"The cloud features can be improved."

"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."

"The logging details need to be improved."

"Fortinet FortiGate can improve by integrating the web application firewall and the DDoS protection part of the solution. Having a WAF feature, web application firewall, and proxy together would be a good benefit."

"There is a lot of improvement needed with SSL-VPN."

"The debugging and troubleshooting has room for improvement."

"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."

"In some cases, its initial setup could be hard for customers."

More Fortinet FortiGate cons

"There is room for improvement in SSL inspection."

"There should be more technical documentation."

"They should improve IPEs for security in the future."

"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."

"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."

"The user interface could be improved, and the DNS section should be more intuitive."

"The reporting part could be better."

"The interface of the solution is an area with shortcomings."

More OPNsense cons

"The price is a significant factor. Mostly in India, the customer service has many hurdles to get real support."

"We face some challenges when we upgrade the solution."

"The engine provided initially was quite heavy, creating a trade-off between software and hardware-based threat management."

"An area that could be improved is the export and import settings functionality."

"The price is a significant factor."

"I would like to see the reporting opened up and have several more opportunities for automatic reports."

"SonicWall NSV's SSL VPN could increase its number of users to 100-plus users."

"SonicWall NSV's initial setup is complicated and requires good knowledge."

More SonicWall NSv cons

Pricing and Cost Advice

"Its price could be better."

"The pricing is flexible."

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."

"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."

"Fortinet FortiGate as a less expensive solution than Palo Alto."

"It's a very full-featured and it's priced well solution."

"The price of Fortinet FortiGate is the lowest in the market."

"It has a competitive price."

More Fortinet FortiGate pricing and cost advice

"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."

"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."

"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."

"OPNsense is open source software so at this time it is free for us to use."

"As an appliance, it's in the medium price range."

"We are using the paid version."

"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."

"OPNsense is a well known open-source tool."

More OPNsense pricing and cost advice

"The tool is moderately priced."

"SonicWall NSV is not very costly."

"Our initial purchase, which included a three-year term of support, was about $25,000 USD."

"We are currently using the trial version."

"The solution’s pricing is less compared to other products."

"The solution's pricing is good for the technology it offers."
