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.

"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."

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

"The most valuable feature of OPNsense is compatibility."

"The interface and the dashboard are the most valuable features of this solution."

"OPNsense is very stable, easy to upgrade, and maintain."

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

"OPNsense can be deployed in the cloud and on-premises, and I have used OPNsense in many different types of companies, such as financial and metropolitan."

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."

More OPNsense pros

Cons

"I would assess the effectiveness of Netgate pfSense Plus Firewall_VPN_Router's traffic shaping as good, but I would give a six marks only for that compared to others because in the past few years, there has been a stop of improvement or lack of improvement showing in Netgate pfSense Plus Firewall_VPN_Router."

"They have to learn something more from FortiGate."

"The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options."

"The most significant drawback in recent years has been the cessation of firmware release downloads."

"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."

"The ability to set the VPN IP address would be a welcome addition."

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

"In our experience, OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

"On the customer-side, because I'm a small business, I need a cheaper or free solution option."

"I would like better documentation concerning the provided packages and their integration."

"The interface of the solution is an area with shortcomings."

"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."

"The interface needs to be simplified. It is not user-friendly."

Pricing and Cost Advice

Information not available

"OPNsense is open source software so at this time it is free for us to use."

"It's not expensive."

"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."

"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."

"We are using the paid version."

"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."

"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."
