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.

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

"I would recommend using Fortinet FortiGate because of its usability."

"The most valuable features of Fortinet FortiGate IPS are firewall and filtering."

"There has been no attack on our servers after we configured the FortiGate IPS."

"I love the interface."

"Fortinet FortiGate's reliability is valuable."

"LinkGreat firewall capabilities"

"Integrated management would probably be the most valuable feature."

"There are multiple features I have found to be valuable, such as encryption and integrated security features."

More Fortinet FortiGate pros

"I would rate the stability as ten out of ten for IPFire."

"IPFire has prevented any kind of hacking and enables us to comply with customer requirements."

"I find everything valuable in OPNsense; the configuration and reporting aspects are what we require, reporting on user access and data consumed is fascinating in OPNsense, and the configuration offers a clear idea of everything that I have configured in DHCP."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

"We have been operating here in our lab for several months, and everything appears to be extremely stable."

"The solution is user-friendly and easy to configure."

"The tool's integration is more like a button press."

"The technical support is very good."

"We have found pretty much all the features of the solution to be valuable."

"OPNsense is suitable for Small to Medium-sized companies."

More OPNsense pros

Cons

"Fortinet FortiGate can improve performance. There was a huge challenge in terms of CPU and memory where the IPS engine would keep triggering. There were random spikes of overutilization in the CPU and memory resources. They have to work on CPU and memory stability considering these IPS engines. A few versions were very unstable."

"We haven't tapped into most of the functionalities that Fortinet FortiGate offers because we're using it just for gateway security. One of the things that I would prefer is a more expansive use of their analyzer. They could do more work on FortiAnalyzer in terms of the data and the information coming from it."

"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production."

"It claims it does DLP, but the degree and level of controls are very basic."

"Stability and technical support are the two major issues I have found with Fortinet."

"The captive portal could be improved."

"Their licensing should also be improved. The activation or renewal of the product should be done from the date of renewal, not from the date on which the license expired."

"There are no areas that need improvement at this point in time."

More Fortinet FortiGate cons

"Accessing the internet was a bit complicated."

"The graphical interface could be much better."

"In our experience, OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

"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 interface needs to be simplified. It is not user-friendly."

"The IPS solution could be more reliable."

"FortiGate is a better firewall but that is commercial software that you have to buy a license for."

"The solution could be more secure."

"It is stable, but for us, it is not yet so reliable."

"The documentation should be clearer because I faced some difficulties navigating many options."

More OPNsense cons

Pricing and Cost Advice

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"Its licenses cost the same for different subscription plans."

"The price, in comparison to other products is very cheap."

"I would rate the pricing a five out of ten"

"Pricing for Fortinet FortiGate SWG is more suitable for enterprise or large-sized organizations because they are the ones who can afford it versus small and medium-sized organizations."

"For our organization, the licensing costs are approximately $7,000 per year."

"Work through partners for the best pricing."

Information not available

"As an appliance, it's in the medium price range."

"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."

"We are using the paid version."

"It's a free solution."

"There are no licensing costs for OPNsence."

"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."

"It is open source and free."

"It is free."
