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.

Good for enterprise-level businesses and offers many features like URL filtering and antivirus capabilities
Palo Alto can improve the web application firewall (WAF) feature at layer 7. Currently, I don't think it's available. If they can improve that, it would be better. We wouldn't need to purchase a separate WAF solution because they already have advanced URL filtering. But I don't think that advanced URL filtering has the same features as a dedicated WAF, like F5 or other solutions. That is an area for improvement. If they can improve the WAF feature, customers won't have to buy a separate WAF solution. They could do it with the same Palo Alto firewall, perhaps through a subscription-based model. So the web application firewall feature has to be improved.

Quotes from Members

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

Pros

"The CLI and GUI do a good job of putting a lot at your fingertips."
"Anti-Spam web content filterinG."
"The web filtering feature and the intrusion protection system are the most valuable. It is a resilient appliance. I never had an issue with it in terms of any security breaches."
"I like that they have given me a solution at a fair price."
"I really like the captive portal feature for our guest network. It has nice VLAN features in terms of separating our network. The anti-virus is also good."
"Fortinet FortiGate's reliability is valuable."
"The most valuable features are simplicity, management, and that it's constantly evolving."
"It's very fast and easy to configure."
"The interface and the dashboard are the most valuable features of this solution."
"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."
"OPNsense is easy to scale when running on the hardware."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"OPNsense is very stable, easy to upgrade, and maintain."
"It is stable when you set up something and put it into production. Once it works, you don't have other tasks or actions to perform."
"The solution has a three-layer architecture, and it helps customers to deploy the solution quickly."
"The product's initial setup process was simple."
"Palo Alto Networks firewalls offer single-mode panel processing with live scanning."
"A valuable feature that we can consider is the deployment time, which is significantly reduced. It is almost 90% faster compared to other solutions."
"App-ID is a really good feature."
"It offers application-based policy enforcement. Palo Alto Networks firewalls help us recognize protocol anomalies, contrasting with other vendors that may require policies based on port numbers. With Palo Alto Networks, the port number isn't a constraint because their devices handle protocol traffic at Layer 7, allowing for accurate identification of protocol usage and port numbers. They can identify which protocol actually uses which port."
"The cloud-based aspect helps significantly. It integrates seamlessly with other Palo products like Prisma Cloud, offers robust VPN protection, and it's all in one convenient package."
 

Cons

"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."
"It would be good if they had fewer updates."
"The support system could be improved."
"I would like to have logs, monitoring, and reporting for a month without extra fees."
"Fortinet FortiGate could improve by having better visibility. Palo Alto has better visibility."
"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."
"FortiGate support could do some improvements on their IPv6 configuration. Right now it's still in the very early stage for utilizing in an enterprise level network environment."
"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
"Its interface should be a little bit better."
"The ability to set the VPN IP address would be a welcome addition."
"The IPS solution could be more reliable."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"The interface needs to be simplified. It is not user-friendly."
"They should improve IPEs for security in the future."
"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."
"Compared to other vendors, the solution's community should be strong enough to solve the problems engineers face."
"The technical support offered by Palo Alto is an area of concern where improvements are required."
"Palo Alto can improve the web application firewall (WAF) feature at layer 7."
"The pricing of the solution needs improvement."
"The product's high prices are an area of concern where improvements are required."
"I experienced some problems with AWS cloud parameters connected to Palo Alto firewall."
"The web interface is slow."
"The interface is complex."
 

Pricing and Cost Advice

"Easy to understand licensing requirements."
"Pricing is lower than Cisco."
"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."
"We are on an annual license to use Fortinet FortiGate."
"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."
"Pricing and licensing is a little bit complicated in FortiGate. They are always on the higher side. This is one issue that we always raise with the company that they should reduce the price according to Indian market requirements. There are no costs in addition to the standard licensing fees."
"The pricing is flexible."
"Fortinet FortiGate is expensive."
"As an appliance, it's in the medium price range."
"It is free."
"OPNsense is an open-source solution and it is free to use."
"The solution is not expensive."
"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."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"We are not paying any licensing fees. OPNsense is completely free for us."
"This product has an affordable and reasonable price point."
"The prices are pretty high, definitely on the upper end."
"The pricing is fair."
"From my perspective, managing the price is important, especially because we're a small business. For larger organizations like Barclays, we provide our requirements to the client, and they place the order on BigFix. It's their responsibility to consider their budget and make decisions accordingly. We appreciate the features we get, but the cost-sharing still depends on the client."
"Palo Alto Networks PA-Series's price is much higher than other firewall brands."
"With Palo Alto, even when you enable all the modules, it still provides the exact throughput they advertise."
"The product is offered to users at high prices compared to the pricing model of the other vendors in the market."
"It is a very expensive solution."
