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

"The feature I like most is the SD-WAN. It allows you to manage more than one ISP at the same time. And there is a high-availability mode, so if one of your ISPs is down, you still have a backup."

"What I like the most is the configuration and that it's simple, and straightforward to maintain."

"It increases security posture and is helpful for firewall reporting, intrusion protection, web filtering, and SD-WAN implementation."

"Their proxy-based inspection is responsive and secure."

"You can create multiple Virtual Domains (VDOMs), which are treated as separate firewall instances."

"It has very easy management and an amazing ETM configuration."

"The GUI is good."

"The wireless control is helpful."

More Fortinet FortiGate pros

"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."

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

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

"OPNsense is highly stable."

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

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

"The DNS-level filtering is impressive for thwarting time scanners."

More OPNsense pros

Cons

"If they had better integration with security products, such as Cisco ISE or Rapid Threat Containment, then it would be an improvement."

"The support we receive when we need to upgrade is not satisfactory and has room for improvement."

"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."

"The configuration part was challenging, especially converting configurations from another OEM to FortiGate."

"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."

"Fortinet FortiGate is a stable solution. However, my issue is the performance only. When I use all the profiles, this affects the performance. From the beginning, I should have had a better sizing of the box."

"The renewal price and the availability could be improved."

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

More Fortinet FortiGate cons

"When using the solution at the beginning was difficult. There was a steep learning curve."

"There are issues with stability and reliability."

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

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

"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."

"There should be more technical documentation."

"The IPS solution could be more reliable."

More OPNsense cons

Pricing and Cost Advice

"The price is high compared to some of the other solutions."

"The price of Fortinet FortiGate when compared to other solutions is high. However, my knowledge of the price is from third parties and I am not sure how accurate it is. I typically work in the technical area of my organization."

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."

"The price of FortiGate support is too expensive."

"The price is highly competitive when compared to other brands that offer similar functionality."

"Fortinet FortiGate gives you most of the features in one license."

"The license is too expensive to renew. The license renewal process is also complex."

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

More Fortinet FortiGate pricing and cost advice

"The solution is not expensive."

"It costs about $1000."

"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."

"There are no licensing costs for OPNsence."

"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."

"OPNsense is an open-source solution and it is free to use."

Sophos UTM vs. Fortinet FortiGate

I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
