Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Perimeter security has reduced botnet attacks and now needs better interface and logging
The best features Arista Edge Threat Management NG Firewall offers are its ability to push a lot of traffic along with bandwidth management and traffic policy. Bandwidth management and traffic policy help my organization by keeping our internet subscription low. Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks. Immediately after I installed the firewall, it stopped a few botnet attacks.

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 solution is very stable; it doesn't have bugs or glitches, it doesn't crash or freeze, and it's reliable."
"Valuable features include the performance, stability, and virtual domain ability as well as the management that it provides."
"FortiGate is a scalable product and our customer has approximately 2,000 users."
"Fortinet FortiGate is a scalable solution."
"The Fortinet FortiGate local partners were good."
"It's easy to manage. The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."
"The solution provides an easy way to filter information and Fortinet lab is a great place to discover new things."
"It's super reliable, I don't think I've ever had a reliability issue with it."
"Phish Blocker is a valuable feature."
"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."
"The product's initial setup phase is easy."
"Its user interface is one of the best interfaces I have used."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
"OPNsense is highly stable."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"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."
"Its pricing is unbeatable in comparison to other firewalls."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"It has an open license. It works very well, and there is an update every month."
 

Cons

"We would like to see a better training platform implemented."
"There are some problems that support cannot give you a logical reason as to why it happened. For example, I had a case where I was dealing with a WhatsApp application that was giving issues. Technical support gave more than one reason it could be giving issues, but none of them solved the problem. Eventually I solved the problem, but it was far from the solutions that support had given."
"They can probably improve the reporting feature. Reporting and report alerting are the main key features of this solution. They can always find ways to improve these."
"They have not yet extended to the cloud."
"The user interface could be improved to make it less confusing and easier to set up."
"One area for improvement is the performance on the bandwidth demands for smaller devices, as well as better web filtering."
"The solution needs to improve its support."
"Vulnerability scanning could be improved."
"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."
"The product has a lot to improve in the area of policy implementation."
"The documentation is not clear."
"There should be more technical documentation."
"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 is room for improvement in SSL inspection."
"The interface needs to be simplified. It is not user-friendly."
"There are issues with stability and reliability."
"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."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"Pricing in my opinion is just too expensive. It makes no sense. It moves in the direction of a monopoly."
