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.

High availability routing has secured our network and delivers reliable support every day
One downside of Netgate pfSense Plus Firewall_VPN_Router is the need for a better understanding of what hardware it would run on. Right now, we're using Netgate's hardware, but I'm interested in knowing if there are other hardware options available, particularly heavier duty hardware, because the Supermicro 1537 version we have only has a single power supply, which is a shortcoming in an IT environment where dual power supplies are ideal. The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options. I'm familiar with the costs of Supermicro servers, and I believe Netgate charges a premium for their server hardware without enough upside to justify it. The pricing is not justified.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most helpful features of FortiGate include its firewall policy, specifically the user-based policy, which I find to be quite beneficial in managing our network security effectively."
"It is a reliable solution."
"The best feature of Fortinet FortiGate is value for money."
"The most valuable features of Fortinet FortiGate are it is one of the most mature firewalls in the UTM bundle."
"UTM/NGFW features and FortiCloud for logs and backups are awesome."
"The SD-WAN feature of Fortinet FortiGate has been most impactful in maintaining our network's integrity."
"On a scale of one to ten, I rate this solution 10 out of 10."
"Fortinet offers comprehensive security solutions for various purposes."
"Overall, the entire Netgate pfSense Plus Firewall_VPN_Router product has been reliable, though some of their smaller gear aimed at remote offices hasn't been cost-effective."
"It's very simple to use, efficient, up to date, and the hardware is very available; it's very safe."
"I do not have complaints about Netgate pfSense Plus Firewall_VPN_Router with Firewall, VPN, and Router; it is really comfortable for use, and it does a pretty good job."
"It's more secure and more reliable."
"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."
"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."
"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 has an open license. It works very well, and there is an update every month."
"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 is very stable, easy to upgrade, and maintain."
"It has firewall and VPN capabilities, which are very valuable features."
 

Cons

"I see room to explore its integration with Secure Service Automation for a more comprehensive security view."
"It could use better throughput on some of the smaller boxes for the branch offices."
"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."
"There is a need for enhancement with the signature management, improving the datasheet numbers, and scalability issues."
"There are problems with the custom reporting of the unique traffic. The data is there, but it is too difficult for us to extract."
"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."
"Maybe they can offer a smaller scope for a cheaper price for smaller organizations."
"The feature which gives us a lot of pain is ASIC architecture."
"The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options."
"The effectiveness of Netgate pfSense Plus Firewall_VPN_Router traffic shaping is quite good, but I am not very satisfied with the interface for control."
"There are issues with stability and reliability."
"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."
"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."
"The solution could be more secure."
"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 should be more technical documentation."
"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."
 

Pricing and Cost Advice

"I would say that all things considered, the pricing is pretty good."
"Its licenses cost the same for different subscription plans."
"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."
"The price of the license and warranty can be better because it is very expensive."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"Fortinet is competitive price-wise."
"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
