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

"The solution can scale well."
"The application control features, such as Facebook blocking and Spotify blocking, are the most valuable."
"The product is easy to install since we only need to follow the user manual, documents, and articles provided by Fortinet to install the product."
"It is complemented by other equipment, such as the Fortinet switch, and it is integrated with other tools that help to prevent cyberattacks, including a web filter, IPS, and application control."
"Overall, the pricing of the solution is very good. The product offers good value."
"It is easy to manage, and it doesn't need much knowledge from the team. It is a stable device, and there are many features that are included out of the box."
"FortiOS is quite good in my experience with Fortinet FortiGate, and it works very effectively and is stable for companies. The customers have given feedback that FortiOS has been very stable for a long time."
"I love the interface."
"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."
"It has an open license. It works very well, and there is an update every month."
"The interface and the dashboard are the most valuable features of this solution."
"I feel that its valuable features are that it is simple and free."
"OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing, and the flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers."
"OPNsense definitely gives me peace of mind and helps my workflow because of the network isolation, as I can have multiple subnets without having to worry about one affecting the other."
"The initial setup is easy. It only takes 15-30 minutes to deploy."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"It was easy to initially deploy it."
 

Cons

"The UI could be improved."
"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 FortiGate could improve by having more capabilities for troubleshooting VPN connections. For example, I do get some feedback about the current status, but I could use some history and logging of important events. The information is logged in our Syslog server, but I could use that information from the device. If they could provide a GUI to have some more insight on what's going with my VPN would be useful."
"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"They should do a better job in testing when they put out a new release because when a new software version is released, it is not always stable or does not always have all the previous features working correctly."
"In the scenarios coming from Sophos, it has not."
"It would be better if they had a dashboard where we could see what attacks were happening. It would be good to see who's trying to get into our network."
"We can't identify which users are causing challenges when we have issues."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."
"The reporting part could be better."
"You will need additional training before you can actually start to use it."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"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."
"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."
"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

"FortiGate Next Generation Firewall is a very cheap solution."
"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."
"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"The license of Fortinet FortiGate should be reduced."
"I give the pricing a nine out of ten."
"Its price could be better."
"The licensing costs are very competitive."
"Its pricing is good. It's average or normal as compared to Palo Alto and Check Point firewalls."
"There are no licensing costs for OPNsence."
"As an appliance, it's in the medium price range."
"OPNsense is a well known open-source tool."
"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."
"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."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"We are using the paid version."
