Enables customers to manage security effortlessly with intuitive features and easy integration

In terms of improvements for Fortinet FortiGate, they could offer evaluation licenses, as compared to Meraki, which provides a 90-day evaluation. In Fortinet FortiGate, they do not provide standard evaluation licenses; instead, we need to request them from the OEM through the account manager for POCs. If we want to conduct a demo, we need to work with real hardware. In comparison to Cisco, we have DCloud, which helps with providing demos to customers, but in Meraki, I need to reach out to them, book a lab, and they need to provide all the hardware. I need remote access and L3 engineers to program it; only then can I offer a real-time demo to the customer.

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.

Enhanced threat detection with integrated security features and good support

We are using application firewalling, WAF, and SD-WAN. The capabilities are mostly within the box. For example, you will get web application firewall WAF as part and parcel of this. SD-WAN is also bundled. It integrates with their SIEM and SOAR solutions very nicely. Lastly, the pricing point is very cost-efficient as well.

Quotes from Members

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

Pros

"The response is very quick and they can visually resolve our problems in a short period."

"The Fortinet technical support is awesome."

"Generally, every aspect of it being a next-generation firewall provides good value."

"I would rate the scalability of this product a nine out of ten because it is highly scalable. We have not had problems with customers in terms of scalability."

"In almost every case, I've experienced (or had customers experience) an ROI within 12 months, based on better performance for the same price or increased functionality for the same (or less) price."

"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."

"What I appreciate about Fortinet FortiGate is that the UI is easier than what I've previously known from Sophos."

"This solution has helped us have control over our network."

More Fortinet FortiGate pros

"The DNS-level filtering is impressive for thwarting time scanners."

"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."

"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."

"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."

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

"OPNsense is easy to use and open source."

"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."

"OPNsense is highly stable."

More OPNsense pros

"It enables us to not only detect but also prevent various types of incoming threats, allowing us to take appropriate corrective actions and exercise control over the network."

"While the features are not dissimilar to other brands, configuration is much more simple, which works out great for Indonesian people."

"Sangfor is a good solution that provides a WAF and firewall solution; most other vendors, like Sophos and Fortinet and Cisco, only provide one solution, and that's a valuable feature of Sangfor."

"The most valuable features are the WAN optimization, the internet access gateway (IAG), and the central console, which allows us to implement on their firewall."

"I think Sangfor NGAF is more valuable than Cisco products because of its simplicity and ease of management. If I compare it with Palo Alto and Cisco, both are quite complex products. And if I compare it with FortiGate firewalls from Fortinet, I have also used all these products. Fortinet and Sangfor NGAF are similar products because the applications behind the application and policy layers are almost identical."

"In terms of the most valuable features, the IPS report is quick and updated, and performance is also valuable."

"Sangfor NGAF's standout feature is its powerful application control, enabling precise restrictions on mobile user access to approved applications."

"The stability of Sangfor NGAF is good."

More Sangfor NGAF pros

Cons

"It's my understanding that more of the current generation features could be brought in. There could be more integration with EDRs, for example."

"The solution needs to improve its integration with cybersecurity."

"FortiOS is not simple."

"The technical support from Fortinet FortiGate is terrible. They can improve."

"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."

"I would like to see improvements in the product's application rules."

"In their IPS Web Security Gateway, the reporting functions need to be a little bit more user-friendly for how to get the reports from it."

"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."

More Fortinet FortiGate cons

"There are issues with stability and reliability."

"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."

"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."

"OPNsense can be improved by making it more user-friendly, as its current UI is not that user-friendly when compared to paid software such as Sophos."

"The monitoring is a little complicated and I have tried to use a plug-in, but it's quite complicated to configure."

"pfSense has better performance and quicker updates."

"There should be more technical documentation."

"The user interface could be improved, and the DNS section should be more intuitive."

More OPNsense cons

"Sangfor could improve their interface capacity on the 5100 series model and upgrade their hardware from one gig to 10 gig. This would improve the overall throughput."

"An area for improvement would be the number of ports defined on the box. In the next release, I would like them to develop their provisioning stage of enrolling end devices."

"I would be happy if Sangfor developed a firewall designed specifically for home use, as well as for small businesses such as clinics and so on. A household version of the Sangfor firewall for your personal computer or laptop would be ideal, in my opinion."

"Sangfor NGAF could improve the policies and default criteria. They could be much better."

"The support offered by the product has certain shortcomings where improvements are required. The knowledge levels and response time of the support team need improvement."

"The user interface isn't user-friendly though."

"I believe that IAM and NGFW need to merge into a single box, instead of there being two separate box solutions."

"The setup phase is quite complex."

More Sangfor NGAF cons
