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.

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

"Provides good firewall security and has great VPN features."

"You can purchase switches and you don't need to do anything with them. You just put in the firewall and the switches get all the policies and rules that you already have in the firewall. With Fortinet, you just connect the FortiSwitch to the Fortinet and that's it."

"The IPS is good. It protect my network from attackers."

"Integrated management is a very valuable feature."

"Overall security features and performance routing is good."

"The best features of Fortinet FortiGate are UTM, web filtering, and IPS."

"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

More Fortinet FortiGate pros

"OPNsense definitely gives me peace of mind and helps my workflow because of the network isolation, as I can have multiple subnets without having to worry about one affecting the other."

"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."

"The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."

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

"It's more secure and more reliable."

"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."

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

More OPNsense pros

"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. That's a valuable feature of Sangfor."

"I think the tool has the feature to detect and kill ransomware in three seconds."

"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."

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

"The product is very fast and reliable."

"It offers application control features."

"The built-in features function as intended, providing exceptional value."

"You might try Sangfor if you are on a tight budget. The price is affordable, and Sangfor offers a lot of features. We don't have any complaints about Sangfor."

More Sangfor NGAF pros

Cons

"There is room for improvement in being proactive about identifying and integrating new signatures."

"Fortinet FortiGate could improve by having more storage in the hardware for log data."

"There are some tiny bugs that sometimes affect the operations. In the past revision of it, there was a bug. Because of the bug, we had to downgrade the version. It happened only with the last revision."

"More SD-WAN features can be integrated into the FortiGate Next Generation Firewall"

"Its customer service could be better."

"There is an area for improvement in vulnerability management."

"Another issue is how deduplication services don't work reliably after enabling deduplication on Fortinet."

"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."

More Fortinet FortiGate cons

"There should be more technical documentation."

"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."

"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."

"You will need additional training before you can actually start to use it."

"When using the solution at the beginning was difficult. There was a steep learning curve."

"While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."

"Pricing in my opinion is just too expensive. It makes no sense. It moves in the direction of a monopoly."

"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."

More OPNsense cons

"An area of improvement for Sangfor NGAF could be in the field of reporting and logging."

"Sangfor need greater exposer in the market because the market is mainly saturated by Fortinet. The user experience of Fortinet is quite different compared to NGAF. If we want to switch our users from Fortinet to NGAF, we have to convince them that the user experience will be much easier once once they start to use it."

"The solution has too many bugs and these slow down the implementation."

"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."

"The GUI needs to be improved, lacks logic in some areas."

"The tool's support is an area of concern where improvements are required."

"The reporting and log management could be improved."

"The support for YouTube or the Internet is not enough."

More Sangfor NGAF cons

Pricing and Cost Advice

"The price is high compared to some of the other solutions."

"The platform offers a reasonable price point compared to its competitors."

"Fortinet FortiGate has different licensing models, depending on what you're going to do. Services included would depend on the license model. Licenses can be renewed annually."

"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."

"It was worth the money overall. It's good value."

"The solution is very expensive so pricing is rated a one out of ten."

"Although the solution's pricing is high, compared with other products, it may be cheap."

"The pricing is very reasonable."

More Fortinet FortiGate pricing and cost advice

"OPNsense is a well known open-source tool."

"We are not paying any licensing fees. OPNsense is completely free for us."

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."

"It is free."

"OPNsense is an open-source solution and it is free to use."

"We are using the paid version."

"The solution is not expensive."

"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."

More OPNsense pricing and cost advice

"When it comes to the price of firewall solutions, Sangfor NGAF takes the cake."

"The pricing is reasonable."

"The price could be more competitive."

"The product is very cost-effective compared to other brands or vendors."

"Sangfor NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."

"The license of Sangfor NGAF can be purchased at different interval lengths, such as annually or three years. They offer a range of packages to choose from, such as combo or hybrid packages. We are using the complete solution package which includes IM, NGF and SSL VPN, and WAF."

"Sangfor NGAF price is reasonable and there is an annual license. However, the maintenance cost can be a bit high."

"The price falls in the mid-range, neither exceptionally low nor high."
