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.

Quotes from Members

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

Pros

"Fortinet FortiGate's ease of management is the most valuable feature."

"The solution is very easy to understand. It's not overly complex."

"I like several features that this product has, such as antivirus and internet navigation inspection. It is also simple to use."

"I'm looking forward to FortiGate's dashboard features, insights, application oversight, and monitoring, which could help us significantly."

"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."

"One of the valuable features is a standardized OS."

"The customization potential is quite impressive."

"The features that I have found most valuable are the SD-WAN and their IP4 policy."

More Fortinet FortiGate pros

"I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed."

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

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

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

"The most valuable features of OPNsense are the GUI and frequent updates."

"It's more secure and more reliable."

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

"The technical support is very good."

More OPNsense pros

"SonicWall has helped us deliver security solutions effectively, particularly in threat prevention and content filtering."

"The VPN functionality is really good. Overall, the whole device is very easy to manage. The software that comes with it is also good."

"I like the filtering feature, which provides easy access. The SSL certification feature is also nice. The solution enhanced our security posture."

"The solution's pricing is good."

"It has been delivering results efficiently. Its configurations and updates have been easy. It is also user-friendly."

"SonicWall NSSP is stable and scalable too."

"The product's most valuable features are simplicity and comprehensive protection capabilities, including load balancing, IPS, antivirus, and web filtering."

Cons

"The updates Fortinet provides are sometimes unstable."

"In terms of what could be improved, the SD-WAN is quite difficult, because if you install the new box, 15 is okay, but if you change from an old configuration, if there is already configuration and a policy when you change to SD-WAN, you must change the whole policy that you see in the interface."

"Technical support needs to be improved."

"Cisco Meraki products are rising very quickly in the cloud and the connected era. Meraki products offer much better ROI, upgradability, and manageability."

"The main aspect of FortiGate that could be improved is load balancing. Our management team does not want to buy another appliance for only load balancing."

"Its customer service could be better."

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

"There could be more integration between the logging and analytical platforms to make it more seamless and integrated."

More Fortinet FortiGate cons

"The solution would not be suitable for anything large-scale."

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

"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."

"An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."

"There is room for improvement in SSL inspection."

"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."

"There should be more technical documentation."

"I would like better documentation concerning the provided packages and their integration."

More OPNsense cons

"The solution's stability and scalability also need improvement."

"Its reporting functions can be improved. It has decent reporting, but you got to pay a lot more money for it. That's where it begins to fall apart. It comes with minimal zero reporting unless you buy some extra modules. With those extra modules, you can get all the data, but it takes a while to put together what you need for your customer. It is for technical people, but there is no executive summary of the reporting."

"The EDR and XDR capabilities of SonicWall need to be improved."

"The user interface, the GUI, could be improved."

"The platform could benefit from an improved marketing strategy."

"The product needs improvement for phishing emails."

"No security product is foolproof against hackers, intruders, and other such things. As a security product, they have to keep pace in terms of protection from new hackers and intruders."

Pricing and Cost Advice

"I would say that all things considered, the pricing is pretty good."

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

"The price is fine."

"Licensing for Fortinet FortiGate is on a yearly basis. Pricing for it is a bit high. It could be cheaper."

"Fortinet is the least expensive solution."

"Compared to Palo Alto, which we have used in the past, pricing and licensing are okay."

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

"They are very competitive, but we like to have the factory warranty taken care of."

More Fortinet FortiGate pricing and cost advice

"We are using the paid version."

"It's not expensive."

"The price of OPNsense is good."

"The solution is not expensive."

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

"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."

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

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

More OPNsense pricing and cost advice

"The setup costs and licensing are reasonable, and the solution provides good value for its features."

"You got to buy some VPN licenses, and there might be a $40 to $50 one-time license fee per current user. There are different layers. They have several different levels of event security software and depending on the model, it seems to come out to be $1 to $2 a day. So, if you bought a three-year license, it is going to be anywhere from $900 to $1800 depending on the bundle and model that you buy."

"I rate the solution's pricing a six out of ten."

"The pricing is cheap, and that's where, you know, the some of the organization goes for the SonicWall."

"For SonicWall NSSP high availability, active/passive, you need to buy one license, and so you get much more value for money."
