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.

The intrusion detection system helps our organization by automatically detecting and responding to potential threats

The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page. The intrusion detection system helps our organization by automatically detecting and responding to potential threats. It operates similarly to Darktrace, which detects and responds automatically based on the security rules you apply. Initially, you configure everything to block, and then you can whitelist specific items as needed.

Quotes from Members

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

Pros

"The license management is very valuable. You can get a new license each year, or you can enroll every two to four years. You can get the logs, and you will get the information on the risk in your network and the entire organization. With this information, you can take action on your actives, computers, or devices. You can bring your own device as an SSE."

"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."

"Easy to implement, and it is also reliable."

"The product offers very good security."

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

"Fortinet FortiGate is among the best options in the market."

"The security features are about the best that I've seen anywhere."

"The most valuable features of Fortinet FortiGate are remote access, web filtering, and IPS."

More Fortinet FortiGate pros

"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."

"OPNsense is easy to use and open source."

"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."

"The most valuable features in OPNsense are reporting and visibility."

"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."

"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."

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

"The tool's integration is more like a button press."

More OPNsense pros

"A very robust product."

"Ease of use is the best feature of the product."

"I like how you can configure the rules. There is the task for the rules and a task for the network configuration. It also provides SMD filtering, and it can be integrated with the active directory for the users, their mission, and the VPN configuration. We are here in Sudan, and Stormshield didn't work in Sudan for more than a decade. Stormshield is a very strong firewall and very easy to configure and maintain. I am just working with the firewall solution, and we don't have any other solutions like endpoint solutions or something like that."

"The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page."

"It's an easy, straightforward management platform to use."

"The solution has improved my organization because I can see what traffic is happening and I can use it to block and prevent attacks."

"I can see what traffic is going on. I can easily block any programs from attacks."

"This solution is quick and easy to configure."

Cons

"It should provide better visibility over the network and more information in the form of reports for the end users. Its installation should also be easier."

"Improvements for Fortinet FortiGate could be made by making it easier to implement on networks and simpler to add users and accounts that utilize this solution. That's basically the only challenge that I see."

"In the future, I would like to see improvements made to cloud-based management."

"The updates Fortinet provides are sometimes unstable."

"The feature which gives us a lot of pain is ASIC architecture."

"Its price could be better."

"There are some problems that support cannot give you a logical reason as to why it happened. For example, I had a case where I was dealing with a WhatsApp application that was giving issues. Technical support gave more than one reason it could be giving issues, but none of them solved the problem. Eventually I solved the problem, but it was far from the solutions that support had given."

"A couple of things I've seen that need improvement, especially in terms of a hard coding. The driver-level active moment really is out-of-the-box and we have to have contact the customer support and sometimes it is difficult to resolve."

More Fortinet FortiGate cons

"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."

"I would like to see better SD-WAN performance."

"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."

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

"There is room for improvement in SSL inspection."

"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."

"Its interface should be a little bit better."

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

More OPNsense cons

"Stormshield Network Security is quite expensive."

"It could be better if it were more user-friendly. It's too complicated for us to use it. The price could be better as well."

"Improvement is needed in terms of the technical support of the manufacturer."

"This solution has a big problem with web filtering and it needs to be improved."

"The biggest issue was their support department was not able to help us, then everything stops. This is a no-go area for me."

"Not all the fields are activated yet and we were informed that it will take at least one month."

"The SD card could be more secure."

"This is not a next-generation firewall."

More Stormshield Network Security cons

Pricing and Cost Advice

"It's not the cheapest, but it's value for money. Given everything we've got out of it: the DMZ port, the VPN, and the high availability, it's a pretty reasonable price."

"The license for Fortinet FortiGate is affordable in my country."

"These boxes are not that expensive compared to what they can do, their functionality, and the reporting you receive. Fortinet licensing is straightforward and less confusing compared to Cisco."

"The price of Fortinet FortiGate is reasonable for an SME."

"We have the full license that included all of the features and support."

"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."

"The pricing depends on the FortiGate model we are using, ranging from $3,000 to $20,000 US dollars."

"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."

More Fortinet FortiGate pricing and cost advice

"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."

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

"It costs about $1000."

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."

"The price of OPNsense is good."

"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's a free solution."

"It's not expensive."

More OPNsense pricing and cost advice

"The price of this solution and the price of support are ok."

"I think the price is good."

"We bought a three-year license, and we renew it whenever it expires. The price could be better. It's always very expensive."

"The pricing could be better."

"For mid-sized companies, they sell their appliances for good prices."

"The SN200 series costs between $500 USD and $600 USD per year, whereas the SN700 series costs approximately $1,000 annually."

"We chose Stormshield for its price, as the Azure firewall was too expensive."
