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

"The firewall and VPN features are the most valuable in protecting our customers' networks."
"It's an easy solution to set up."
"The main reason why I purchased the particular unit was that it had good reviews and what other people were saying as far as its completeness and its leading capabilities in terms of endpoint security was very good."
"Overall, I am satisfied with the product."
"The most valuable feature is the bundled subscription, which is IPS, TV and web filtering."
"Fortinet FortiGate meets all the security demands of my industry. It covers endpoint security, including web interface, DNS security, and ELP. I'm currently using the latest version. The features that have most improved our network security are Web Control, filtering, application control, IDS, IPS policies, and Deep SSL inspection."
"The enterprise-level support is excellent, and we receive quick assistance from Fortinet FortiGate."
"There are multiple features I have found to be valuable, such as encryption and integrated security features."
"Overall, I would rate OPNsense as nine out of ten."
"We have found pretty much all the features of the solution to be valuable."
"The technical support is very good."
"The most valuable features in OPNsense are reporting and visibility."
"The solution has high availability."
"OPNsense is easy to scale when running on the hardware."
"It has firewall and VPN capabilities, which are very valuable features."
"The system in general is quite flexible."
"In four steps one can configure the entire firewall."
"We've found the technical support to be helpful."
"In terms of the most valuable features, the IPS report is quick and updated. Performance is also valuable."
"Sangfor's tech features and technologies are more powerful than those of the other solution providers in terms of security. They also have big solutions in terms of cybersecurity."
"So far, the performance and reliability of the product have supported our company's critical network traffic."
"SSL VPN is the best feature."
"Sangfor NGAF works accordingly with our customers. The solution has good performance, easy to use, and integrates well with the endpoints."
"The capabilities are mostly within the box."
 

Cons

"FortiOS is not simple."
"From my experience, I see that the datasheets of the Fortinet FortiGate portfolio need to be more accurate because correct sizing is essential. The datasheets should provide clear information when deploying features."
"Some of the filtering is not robust, you can escape it with a VPN. Some of the users bypass some of the filters. It catches some but it also misses some, that area could be improved. It's functioning reasonably but there's room for improvement in that area."
"We also have FortiAnalyzer deployed here, so we want to enable the soft functionality of FortiGate and built-in compression for a firewall VPN use case. We want the ability to deploy a gateway for HTTPS enabled on this firewall. It is currently only for use in our headquarters."
"It could use better throughput on some of the smaller boxes for the branch offices."
"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."
"The inability to scale the FortiAnalyzer to match our growth necessitates the purchase of new hardware."
"I would like the deployment and integration of this product to be easier. We should be able to deploy the features more easily and have different types of access. It should be easier to integrate. Currently, we need to develop APIs to use this interface."
"There are issues with stability and reliability."
"There is room for improvement in SSL inspection."
"Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine."
"Its interface should be a little bit better."
"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."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"I would like to see better SD-WAN performance."
"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."
"Sangfor NGAF could improve by refining its application control policies, especially in addressing challenges with certain types of applications."
"There is room for improvement in dependency on certain infrastructure, like the DNS dependency on the current DNS server that the company has. It should be standalone. It should not depend on any other DNS server."
"The setup phase is quite complex."
"Sangfor could improve by providing better real-time reporting, as the current reports don't offer the level of detail we need, especially for runtime insights."
"Lacks consistency in terms of filtering certain websites and applications."
"The product must provide more IPS features."
"Sangfor NGAF could improve the policies and default criteria. They could be much better."
 

Pricing and Cost Advice

"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."
"FortiGate Next Generation Firewall costs our company around $12000 per year."
"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."
"It has a competitive price."
"The price of the license and warranty can be better because it is very expensive."
"Easy to understand licensing requirements."
"Fortinet FortiGate IPS' licensing is quite simple to understand."
"I rate FortiGate's pricing a five out of ten."
"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."
"It's not expensive."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"I would rate the pricing three out of ten."
"It costs about $1000."
"OPNsense is open source software so at this time it is free for us to use."
"It is open source and free."
"We are not paying any licensing fees. OPNsense is completely free for us."
"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."
"The price could be more competitive."
"We purchased one year technical support and return to factory support, and we also purchased one-year technical support services. So those were additional."
"I rate the product price as one on a scale of one to ten, where one is low price and ten is high price."
"The price falls in the mid-range, neither exceptionally low nor high."
"For over 2000 users, the cost is around 5000 to 6000 USD. If you want a web application firewall, you have to purchase an additional license for it."
