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

"The secure web gateway module and the application control module are valuable. HA operations are very easy."
"Easy to use support and licensing portal as well as activation process."
"I rate this solution a nine out of ten."
"I haven't configured or experienced any stability issues."
"The solution is secure."
"The common valuable feature for FortiGate is its UTM functionality, which includes various features under a license that is commonly implemented."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."

"The DNS-level filtering is impressive for thwarting time scanners."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"Overall, I would rate OPNsense as nine out of ten."
"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's more secure and more reliable."
"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."
"It was easy to initially deploy it."
 

Cons

"It's one of the more expensive brands."
"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."
"Technical support needs to be improved."
"There is a need for enhancement with the signature management, improving the datasheet numbers, and scalability issues."
"Fortinet doesn't provide multiple virtual firewalls which would facilitate end users and customers."
"I think there could be more QoS features"
"The price of the solution could be cheaper."
"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."
"I confirm that I am currently still working with OPNsense and still using their product. However, because of the hardware that I am using, sometimes it ends up freezing quite often, especially the interfaces, most of the busy interfaces."
"You will need additional training before you can actually start to use it."
"There is room for improvement in SSL inspection."
"The reporting part could be better."
"The scalability needs improvement."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"There should be more technical documentation."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"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."
"The solution could be better priced."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."
"We pay about $4,000 for a yearly license, and there aren't any additional fees."
"When comparing the price of Fortinet FortiGate SWG to other solutions it is expensive. The price could be better."
"It is very cost-effective. You get features similar to other firewalls, such as Palo Alto, but at a lower price."
"The pricing of the solution is very competitive."
"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."
"We are not paying any licensing fees. OPNsense is completely free for us."
"The price of OPNsense is good."
"OPNsense is a well known open-source tool."
"I would rate the pricing three out of ten."
"The solution is not expensive."
"It is free."
