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.

Organize networks efficiently while benefiting from strong reliability and support
The main use is for clients who are migrating to the cloud. We started this journey during the pandemic, and the main case is with clients who are moving to either a private or a public cloud The solution allows us to organize our networks and access within one vendor, using an integrated…

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

"Fortigate represents a really scalable way of delivering perimeter network security, some level of layer 7 security, WAF, and also a way to create a meshed ADVPN solution."
"Fortinet FortiGate is a stable solution."
"The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with."
"The most valuable feature is the ease of use."
"It performs very well."
"Fortinet FortiGate has a threat detection capacity compared to other vendors."
"FortiGate SD-WAN facilitated a smooth transition for our customers between their two internet service providers, ensuring uninterrupted connectivity without any downtime."
"It is very flexible to use."
"The customer care center of Fortinet is good. For all the requests that we have done, they work as fast as possible, so this is a good point for Fortinet.​"
"Initial setup is very straightforward with a wizard, if needed."
"​Initial setup was quite straightforward, as we can simply head to the required sections to apply the planned network.​"
"Fortinet FortiGate-VM is easy to use."
"The ROI is good since I get free support."
"I find the simplicity to be most valuable."
"In spite of the solution being inexpensive, it has everything one would need."
"The EPM bundle is a good feature."
"The technical support is very good."
"The tool's integration is more like a button press."
"The solution has high availability."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."
"The initial setup is easy. It only takes 15-30 minutes to deploy."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
"OPNsense is highly stable."
"The most valuable features in OPNsense are reporting and visibility."
 

Cons

"While FortiGate is cheaper than most other solutions, we're seeing increased license renewal costs. Most of our clients are asking for more significant discounts because the price is going up."
"Some of the web policy reports could 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 room for improvement related to the logging and reporting aspect."
"Fortinet technical support is lacking, as OEM support is slightly better."
"It would be a benefit if Fortinet would release a one-stop solution that is better integrated with other products and an automated emergency response system."
"Fortinet FortiGate can improve the integration with Active Directory. Additionally, I would like to have a Cloud Controller, such as they do in the Cisco Meraki solution."
"The cloud features can be improved."
"The previous version 5.6 had integrated features for logging, monitoring, and management. Now, these features require separate products like FortiManager, FortiAnalyzer, and a FortiCloud subscription for reporting."
"Not a ten because I think that Cisco is better."
"The graphical user interface should be enhanced."
"FortiGate-VM could be improved by making it cloud-based. I'd like it to be a cloud-based management solution instead of just a dedicated management orchestration tool."
"Fortinet support needs improvement. The response times are lackluster. Fortunately, the product is stable and we seldom have issues. Also, it takes months for them to deliver hardware when we order it."
"FortiGate should be more customer friendly and budgeted better."
"The stability could be improved. I find Cisco to be more stable than Fortigate, which is I major differentiator between the two."
"The price is problematic."
"pfSense has better performance and quicker updates."
"The scalability needs improvement."
"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."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"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."
"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 IPS solution could be more reliable."
 

Pricing and Cost Advice

"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"It's expensive, but compared to the competition it's okay."
"FortiGate's pricing falls within the mid-range when compared to other leading firewall solutions."
"On a scale of one being cheap and ten being expensive, I rate the tool's price as an eight."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"It is affordable. Palo Alto is much more expensive than Fortinet."
"The license of Fortinet FortiGate should be reduced."
"The price of the solution could be less expensive. There are some features that have to be purchased separately that have their own license."
"There is no additional cost. Once you get the licensing fee, you're good."
"We can tailor the suitable license for the customer, whether they require UTB or enterprise features. The options are flexible based on their needs."
"It is an expensive solution."
"We have been waiting a long time for the vendor to give us licenses, it has been five months and we are still waiting. However, the price is reasonable."
"The price of the solution is competitive. Fortinet FortiGate-VM had a lot of advantages when it came to pricing. However, the competition has also geared up to a larger extent and it has become comparable now to the other solutions."
"At present, the SD-WAN licenses are on an annual basis."
"The price falls somewhere in the middle; it's neither cheap nor expensive."
"It is open source and free."
"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."
"OPNsense is an open-source solution and it is free to use."
"It is free."
"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 costs about $1000."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."
