Manager, Information Technology Operation/Presales at TechMonarch
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Has helped simulate enterprise security setups and strengthens network segmentation practices
For my capstone, I use OPNsense for my project and its broader benefits for enterprise and cybersecurity context. OPNsense is an open source based firewall and routing platform. It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost. This platform has a modular design, a clean web-based GUI, and frequent updates that prioritize security and usability. It competes with commercial firewalls such as Cisco ASA, FortiGate, and Palo Alto, but stands out because it's community-driven, cost-effective, and transparent. I find OPNsense's feature of acting as a central firewall and gateway most valuable, providing robust point segmentation between the internal network and DMZs in my capstone project, intrusion detection to monitor malicious traffic, VPN services for secure remote access, and logging and monitoring for compliance and auditing. This allows me to simulate a real-world enterprise environment on a smaller scale, demonstrating both security hardening and network efficiency. OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing. The flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers. The security-first design for IDS/IPS integration helps me showcase modern defense-in-depth strategies. The user-friendly management through the web GUI makes it possible to manage complex firewall rules clearly, which is critical when documenting and presenting a capstone. Scalability is also an advantage. Although my project is lab-based, OPNsense can scale into production deployments in SMBs and enterprise.

Offers good scalability and monitoring features
There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages. For example, if we're creating a rule, we should be able to do everything on the same page. Just a drop-down thing or something. This would improve productivity.

Quotes from Members

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

Pros

"FortiGate IPS is really easy to use. I don't have any problems with this."
"It is useful for protecting and segregating the internal networks from the internet. Most of our customers also use the FortiGate client to connect to their offices by using the VPN client, and of course, they usually activate the antivirus, deep inspection, and intrusion prevention services. They are also using it for web filtering and implementing various policies dealing with forwardings, NAT, etc."
"FortiGate Next Generation Firewall's design is good...I am very impressed with the product's stability."
"FortiGate Next Generation Firewall can be described as the most complete solution."
"The most valuable features of the FortiGate firewall include SSL inspection, VPN functionality, and threat intelligence features for preventing threats."
"The tool is a nice product and easy to handle. The software's user interface is also good. You can easily implement remote access in the solution."
"I appreciate FortiGate for its reliable, powerful, and flexible setups."
"The product is very stable, easy to troubleshoot, and configure, so it has reduced the time it takes for support."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"The solution is user-friendly and easy to configure."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"We have found pretty much all the features of the solution to be valuable."
"The most valuable features of OPNsense are the GUI and frequent updates."
"The technical support is very good."
"The tool's integration is more like a button press."
"The initial setup is easy. It only takes 15-30 minutes to deploy."
"It was easy to initially deploy it."
 

Cons

"Fortinet FortiGate needs to improve the logging and reporting. Additionally, the next-generation application's policies should be improved. When they were released they had bugs."
"The area that Fortinet may improve is customer support."
"It's my understanding that more of the current generation features could be brought in. There could be more integration with EDRs, for example."
"Fortinet technical support is lacking, as OEM support is slightly better."
"The solution needs to integrate VPN features."
"If they could extend their fabric towards other vendor environments for integration, that would be great."
"The initial setup is complex."
"The SD-WAN functionality is a bit overly complicated and not fully documented."
"The solution could be more secure."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"There should be more technical documentation."
"Pricing in my opinion is just too expensive. It makes no sense. It moves in the direction of a monopoly."
"Its interface should be a little bit better."
"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."
"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."
"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."
"There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages."
 

Pricing and Cost Advice

"The cost has increased since the update so I would rate it eight out of ten."
"Its licenses cost the same for different subscription plans."
"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."
"Here in Brazil, we're going through difficult economic times and the tax on the dollar is high. All the solutions from minor competitors are growing in the market. The prices have come more competitive."
"I would rate the pricing a seven out of ten"
"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."
"The price could be lower."
"The initial setup is super straight forward and as far as the licensing goes for the small product that we have, the pricing was pretty competitive. It wasn't as simple and as cheap as a SonicWall but for the service we would get it was a good price."
"As an appliance, it's in the medium price range."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"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 is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."
"It is open source and free."
"The price of OPNsense is good."
"OPNsense is a well known open-source tool."
"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."
