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 most valuable features are the enterprise modeling and the simple interface."

"It's very fast and easy to configure."

"The management console is pretty simple, so anyone who understands networking can initially deploy the solution."

"This is an easy solution to deploy."

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

"It is user friendly, and has all the features you need."

"The most valuable feature is the FortiManager for centralized management."

"We purchased Fortinet because of the pricing, its functionality, because it met our requirements, and the total cost of ownership over five years was quite reasonable. In the market, Fortinet is rated quite well."

More Fortinet FortiGate pros

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

"The solution has high availability."

"OPNsense is easy to scale when running on the hardware."

"The initial setup is easy. It only takes 15-30 minutes to deploy."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

"OPNsense is easy to use and open source."

"It has an open license. It works very well, and there is an update every month."

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

More OPNsense pros

"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.

"The most valuable features are the IPS, the firewall function, and the price."

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

"I like that it works fine. Stormshield is a very good solution."

"A very robust product."

"Our organization's main concern is stability, and this is a stable solution."

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

"The scalability of the solution is good."

More Stormshield Network Security pros

Cons

"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats. Fortinet FortiGate is able to ensure these threats do not enter, but we would prefer to see more proactive alerting mechanisms come out."

"Pricing for it is a bit high. It could be cheaper."

"The sniffing packets or packet captures, can be simplified and improved because it's a little confusing."

"The solution could be more secure and stable."

"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."

"Currently, FortiGate is providing SSL VPN. But they're missing some features that are available in Palo Alto's SSL VPN."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"When we cluster the two Fortinet FortiGate boxes together we have some issues."

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."

"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."

"The reporting part could be better."

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

"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."

"The ability to set the VPN IP address would be a welcome addition."

"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."

"There should be more technical documentation."

More OPNsense cons

"With Stormshield, there are difficulties joining things, and it can be complex depending on the architecture."

"Stormshield Network Security is quite expensive."

"This is not a next-generation firewall."

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

"A more user-friendly interface would be helpful."

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

"The filtering configuration could be better. We have some difficulties with the filtering configuration and the filter extension. It's not that easy. It's not that straightforward. In the next release, I would like to see a reporting system. Stormshield doesn't have any tutorials on how to do the configuration and things like that. They just have documentation on the website. If you want to configure, for example, Cisco or Fortinet, you can find tutorials on YouTube. They show you how to configure the features, and so on. In Stormshield, there is nothing on social media or the internet on how to configure different things. The lack of documentation or the lack of material makes it difficult for others to adopt this solution."

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

More Stormshield Network Security cons

Pricing and Cost Advice

"Each feature costs money, so it is important to study your needs."

"The price is fair compared to the other competitors."

"In the Asian economy in which we operate, FortiGate is expensive."

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

"At the time we bought them, I was satisfied with their pricing; I don't know how the new pricing will be."

"I had to pay for the license for the firewall, but it is guaranteed to have updates. I expect a good service for it. It was about €1000 for a year, and there was no additional cost."

"I find it quite reasonable."

"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."

More Fortinet FortiGate pricing and cost advice

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

"It's not expensive."

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

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

"We are using the paid version."

"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."

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

"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."

More OPNsense pricing and cost advice

"The pricing could be better."

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

"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."

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

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

"I think the price is good."
