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.
Himanshu-Sharma - PeerSpot reviewer
Senior Engineer at Qualic
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 SD-WAN feature is the most valuable. This feature evolved from link load balancing. It has helped us in terms of our uptime and privatizing applications whenever we experience an outage. The SD-WAN feature has been a plus for us. Two-factor authentication has allowed us to add more users in terms of remote working. We have two-factor authentication for remote workers to authenticate them before they get on the network."
"The flexibility and ease of configuration are the most valuable features."
"FortiGate has a very strong unified threat management system."
"The product offers very good security."
"FortiGate is more feature-rich and has a broader range of hardware. T"
"The firewall is pretty good if you understand how to use it. It performs at a very high level, and we are loving it."
"The signature database and zero-day detection are Fortinet FortiGate's most valuable features."
"It does not require a lot of maintenance."
"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."
"OPNsense is very stable, easy to upgrade, and maintain."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"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."
"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."
"The system in general is quite flexible."
"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."
"We saved up to half a million Egyptian pounds, which is nearly $100,000 yearly on licensing or subscription using this kind of software, and the network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet."
"It was easy to initially deploy it."
 

Cons

"They should improve the interface to make it more user-friendly."
"FortiGate NGFW can improve technical support. The engineer who answers the technical support call, email, or phone call, whatever the medium may be. The response time is very bad."
"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."
"I want some additional features. For example, I want something to ensure that when we are using Google email or Microsoft email, or Google Workspace, emails can only be accessed on designated machines given to our employees. I would like them to access data from designated machines, not from any machine. It should work for designated mobiles and laptops. I don't know if Fortinet provides something like that out of the box."
"I would like to have logs, monitoring, and reporting for a month without extra fees."
"With the reports, you can see it, and you can get good feelings so upper management can go, "Oh, wow. That looks pretty." However, it's very basic."
"It's one of the more expensive brands."
"The solution could improve the integration."
"The documentation should be clearer because I faced some difficulties navigating many options."
"OPNsense can be improved by making it more user-friendly, as its current UI is not that user-friendly when compared to paid software such as Sophos."
"Its interface should be a little bit better."
"There should be more technical documentation."
"The IPS solution could be more reliable."
"The interface needs to be simplified. It is not user-friendly."
"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."
"Pricing in my opinion is just too expensive. It makes no sense. It moves in the direction of a monopoly."
"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

"It is less expensive than a Cisco solution."
"It's an expensive solution"
"The price of Fortinet FortiGate is the lowest in the market."
"We have the full license that included all of the features and support."
"The price of Fortinet FortiGate is reasonable for an SME."
"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."
"While slightly more affordable than competitors, it remains relatively expensive due to its inclusive subscription."
"The pricing of the solution is very competitive."
"It's not expensive."
"OPNsense is open source software so at this time it is free for us to use."
"It is free."
"We are using the paid version."
"There are no licensing costs for OPNsence."
"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'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."
"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."
