Vasu Gala - PeerSpot reviewer
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 is a great solution, although initially, it faced challenges in the Brazilian market due to lower brand recognition than Cisco. However, explaining and demonstrating its product format and offerings has proven easy. The cost-effectiveness and better features of FortiGate have made some clients skeptical. We set up a trial period, and they eventually opted for it. Many clients were convinced it was great after experiencing the solution's capabilities firsthand."
"This is a quality product with ok support, and it is better than the competition we've tried."
"All of the features of Fortinet FortiGate are useful and the security protection is good."
"The most valuable features of the FortiGate firewall include SSL inspection, VPN functionality, and threat intelligence features for preventing threats."
"It's very fast and easy to configure."
"It is a very user-friendly solution. Moreover, Foritgate offers good performance."
"Our security improved from being able to put in rules and close off unwanted traffic."
"A strong point of FortiGate is the graphical interface is complete and easy to use."
"The most valuable features of OPNsense are the GUI and frequent updates."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"OPNsense is easy to scale when running on the hardware."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"We have found pretty much all the features of the solution to be valuable."
"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."
"It has an open license. It works very well, and there is an update every month."
"It was easy to initially deploy it."
 

Cons

"Its customer service could be better."
"There should be some open-source training or free training for decision makers, or some webinars should be available."
"They should consider making some improvements regarding the pricing."
"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."
"I think there could be more QoS features"
"Palo Alto has a feature called WildFire Analysis that is unavailable in FortiGate. WildFire is better than a sandbox because it can address zero-day threats and vulnerabilities. It can immediately identify zero-day threats from the cloud."
"It's one of the more expensive brands."
"I would like the deployment and integration of this product to be easier. We should be able to deploy the features more easily and have different types of access. It should be easier to integrate. Currently, we need to develop APIs to use this interface."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"The documentation should be clearer because I faced some difficulties navigating many options."
"I would like better documentation concerning the provided packages and their integration."
"The logging could improve in OPNsense."
"The scalability needs improvement."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"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

"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"The license of Fortinet FortiGate should be reduced."
"I rate the product's pricing a seven out of ten. The additional cost depends on the extra feature requirements."
"The main reason we chose Fortinet FortiGate was that the price was better than the competition."
"The pricing is fair."
"Fortinet is competitive price-wise."
"The product is a little bit expensive."
"The price of Fortinet FortiGate is reasonable."
"It costs about $1000."
"It is open source and free."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"We are using the paid version."
"OPNsense is a well known open-source tool."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"OPNsense is open source software so at this time it is free for us to use."
"I would rate the pricing three out of ten."
