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 most valuable features of Fortinet FortiGate are the ease of use and the UI; it has always provided me with what I needed and I have no need for additional costs that other solutions have, such as Sophos."
"The solution can scale well."
"The product is scalable."
"The product is so stable I don't need to have a cluster."
"The most valuable features of Fortinet FortiGate are it is one of the most mature firewalls in the UTM bundle."
"It has been very stable and reliable."
"FortiGate firewalls are easy to manage through a user-friendly web interface. They also have advanced features like DDoS and DLP. However, I wouldn't recommend enabling all of these features on one device because it can cause performance issues."
"Its administrative panel is very intuitive and simple, and we are able to filter everything on our network and also use the VPN feature, which is important these days when people are working remotely during COVID."
"OPNsense is easy to scale when running on the hardware."
"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 solution is easy to use and is accessible."
"We have found pretty much all the features of the solution to be valuable."
"I moved to OPNsense because it's more secure and more reliable."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"OPNsense is suitable for Small to Medium-sized companies."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
"It was easy to initially deploy it."
 

Cons

"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 ease of use could be improved."
"We have experienced a number of failures when trying to upgrade firmware and the process takes a long time."
"The graphical interface could be improved."
"Its reporting capabilities can be improved. It should have some out-of-the-box reporting capabilities and some degree of customization."
"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."
"The support is very poor with FortiGate IPS and they need to look into fixing it. The senior support agent does not honor their commitments when ordering products."
"I wish Fortinet FortiGate's UI updates would be done in a more simplified way to improve it."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The solution can't compete with next-generation firewalls."
"The reporting part could be better."
"I would like better documentation concerning the provided packages and their integration."
"The logging could improve in OPNsense."
"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."
"The documentation should be clearer because I faced some difficulties navigating many options."
"There are issues with stability and reliability."
"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

"For the performance that we get, the price is reasonable. There are cheaper options, but they may not deliver the same kind of performance that we want. For the performance they provide, the price is acceptable."
"FortiGate SWG is reasonably priced."
"The price of FortiGate support is too expensive."
"I rate the price of Fortinet FortiGate SWG a seven and a half out of ten since it is not a cheap solution, though I feel it is a good product for the money one pays."
"I would rate the pricing a seven out of ten"
"The pricing depends on the FortiGate model we are using, ranging from $3,000 to $20,000 US dollars."
"It is expensive. You need to pay for the subscription every year, which is very expensive. The subscription includes technical support and hardware exchange in case of failure."
"Cost-wise, there is not much difference from Sophos, but feature-wise, we get more features."
"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."
"It is open source and free."
"The price of OPNsense is good."
"There are no licensing costs for OPNsence."
"It's a free solution."
"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."
"As an appliance, it's in the medium price range."
"OPNsense is an open-source solution and it is free to use."
