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.

Offers good features like URL filtering, IPS, and IDS to users
We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

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 configuration possibilities that Fortinet FortiGate provides are extensive, and the task configuration activity is fast and efficient for me."
"User-friendly and affordable security solution that's recommended for SMB customers. This solution has good technical support."
"ROI is exceptionally good."
"The most valuable features of Fortinet FortiGate are the ability to work in proxy mode, which other solutions, such as Palo Alto cannot. There are some features that are better that come at no extra license or subscriptions cost, such as basic SD-WAN. The DLT is useful, other solutions have the same feature too, such as Palo Alto."
"The firewalls are valuable for threat prevention."
"In a scenario where FortiGate Next Generation Firewall (NGFW) notably enhanced my customer's network performance, we discussed many points."
"FortiGate Next Generation Firewall has IBS/IPS systems"
"I would recommend Fortinet FortiGate IPS as it is a core component of cybersecurity for our company."
"The most valuable feature of the Hillstone E-Series is its user-friendliness."
"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."
"The initial setup was straightforward. It only took a few hours to deploy."
"I am impressed with the application filtering feature."
"The most valuable feature of the solution is the ransomware protection that the tool offers."
"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."
"Very reliable solution with good scalability and straightforward implementation."
"Five out of five ROI."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."
"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."
"Overall, I would rate OPNsense as nine out of ten."
"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"It's open source."
 

Cons

"There could be more integration between the logging and analytical platforms to make it more seamless and integrated."
"It would be better if they had a dashboard where we could see what attacks were happening. It would be good to see who's trying to get into our network."
"We understand that FortiGate cannot be standalone without others, such as FortiManager, so for small businesses, if FortiGate can provide something similar to FortiManager, it will be better."
"At the moment, the main concern is the pricing and the type of licensing."
"There should be some open-source training or free training for decision makers, or some webinars should be available."
"Its technical support could be better."
"Regarding challenges, customers initially faced issues like internet dropping, but after firmware upgrades, everything worked well."
"The solution could improve by having some additional features, such as IBS and better cloud administration."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"The current usage reporting is very basic."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"The tool only had some memory-related problems."
"The tool needs to improve its price."
"SSL VPN license cost is not cheap."
"There should be more technical documentation."
"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."
"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."
"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."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"The solution would not be suitable for anything large-scale."
"You will need additional training before you can actually start to use it."
"I would like better documentation concerning the provided packages and their integration."
 

Pricing and Cost Advice

"The license of Fortinet FortiGate should be reduced."
"The setup cost was good. The Egyptian pound is declining, and upgrading Fortinet FortiGate yearly costs about $2000 USD, which equals one hundred Egyptian pounds. I maintain a business relationship with the vendor and receive support from them."
"It's an expensive solution."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."
"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."
"FortiGate Next-Generation Firewall is cheaper than Cisco or CheckPoint."
"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"Hillstone's pricing is economical and neither very high nor very low."
"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."
"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."
"The solution is not expensive."
"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."
"It is free."
"OPNsense is open source software so at this time it is free for us to use."
"It costs about $1000."
"We are using the paid version."
"It's not expensive."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
