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.

High availability routing has secured our network and delivers reliable support every day
One downside of Netgate pfSense Plus Firewall_VPN_Router is the need for a better understanding of what hardware it would run on. Right now, we're using Netgate's hardware, but I'm interested in knowing if there are other hardware options available, particularly heavier duty hardware, because the Supermicro 1537 version we have only has a single power supply, which is a shortcoming in an IT environment where dual power supplies are ideal. The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options. I'm familiar with the costs of Supermicro servers, and I believe Netgate charges a premium for their server hardware without enough upside to justify it. The pricing is not justified.

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

"Simple interface and easy to deploy."
"I do not have complaints about Netgate pfSense Plus Firewall_VPN_Router with Firewall, VPN, and Router; it is really comfortable for use, and it does a pretty good job."
"Overall, the entire Netgate pfSense Plus Firewall_VPN_Router product has been reliable, though some of their smaller gear aimed at remote offices hasn't been cost-effective."
"It's very simple to use, efficient, up to date, and the hardware is very available; it's very safe."
"It has firewall and VPN capabilities, which are very valuable features."
"I feel that its valuable features are that it is simple and free."
"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."
"I mostly rely on the solution's network intrusion detection and prevention system, along with other systems, CMs, and log management."
"OPNsense is easy to use and open source."
"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."
"OPNsense is very stable, easy to upgrade, and maintain."
"The initial implementation process is simple."
 

Cons

"Vulnerabilities owing to viruses in the OS need to be reduced in FortiGate Next Generation Firewall from an improvement perspective."
"Fortinet's support team consists of a huge networking team, because of which there is a delay in response at times."
"There's a limitation wherein you can only have about 30 virtual or secondary IPs on a particular interface."
"The solution could be more evenly structured."
"Fortinet needs to continue to improve network traceability. Other than that, we haven't run into anything that would give me any concern."
"Updating the software during issues can be quite convoluted, especially if there is an unexpected attack, such as on a Saturday."
"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."
"Technical support needs to be improved."
"The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options."
"The effectiveness of Netgate pfSense Plus Firewall_VPN_Router traffic shaping is quite good, but I am not very satisfied with the interface for control."
"There should be more technical documentation."
"There is room for improvement in SSL inspection."
"The solution would not be suitable for anything large-scale."
"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"The ability to set the VPN IP address would be a welcome addition."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"I would like better documentation concerning the provided packages and their integration."
 

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."
"The price of FortiGate support is too expensive."
"It is a cost-effective solution that meets the user's needs."
"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."
"The product is expensive compared to one of its competitors."
"I rate the price of Fortinet FortiGate SWG a seven and a half out of ten since it is not a cheap solution, though I feel it is a good product for the money one pays."
"The price range is quite acceptable and normal."
"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."
Information not available
"The solution is not expensive."
"We are using the paid version."
"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."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"It is free."
"I would rate the pricing three out of ten."
"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."
"The price of OPNsense is good."
