Netgate pfSense Plus Firewall/VPN/Router

My primary use case for Netgate pfSense is network security and firewall management, and I use it to configure stateful firewall rules, NAT, traffic segmentation, and VPN connectivity. I particularly value the flexibility of implementing granular access controls and secure remote access without relying on a proprietary firewall ecosystem.

In my organization, we use Netgate pfSense for VPN-based remote access and to restrict traffic between network segments. I combine WireGuard with Netgate pfSense, and by defining firewall rules around source and destination subnets, I can limit VPN clients to the services they needed instead of granting unrestricted LAN access. This approach is truly important for access management. This approach centralizes access control, reduces unnecessary network exposure, and makes troubleshooting easier through firewall logs and connection state monitoring.

Another benefit I want to add about my main use case with Netgate pfSense is the ability to manage firewall policies, NAT, VPN access, and network segmentation from a centralized interface, which is quite useful. Stateful inspection and granular rule ordering help control traffic flows, while logging simplifies troubleshooting. The modular architecture also allows additional capabilities through packages when needed. For our production deployments, I prioritize measuring VPN performance, CPU utilization, and rule processing overhead under realistic traffic loads.

Netgate pfSense has positively impacted my organization by centralizing firewall policies, VPN access, and traffic segmentation in one interface, which we truly needed. Stateful inspection simplifies connection management, while VLAN-based isolation helps restrict unnecessary communication between network segments. Granular access controls improve control over internal and remote connectivity, and firewall logs make troubleshooting more systematic. It is flexible in terms of configuration, which reduces dependency on proprietary network management tools. The main operational benefit is improved visibility and more consistent enforcement of network access policies, and the actual improvement in uptime, throughput, and administration time should be validated from monitoring data.

In my opinion, the best features Netgate pfSense offers, in order of priority, are stateful firewall capabilities, OpenVPN and WireGuard support, and VLAN segmentation. The first one is the stateful firewall, which is granular rule-based and based on source, destination, IP, ports, and interfaces with connection state tracking. The second best feature is the support for OpenVPN and WireGuard, which is important to secure our remote access and site-to-site tunnels so that the access control stays reliable and working. The third feature is VLAN segmentation, which supports logical network isolation with inter-VLAN traffic control through firewall policies.

Stateful firewall rules and VLAN segmentation have made a difference for my day-to-day work by making network administration more reliable, predictable, and secure. As an example, I can separate management devices from general client traffic using VLANs and then apply inter-VLAN firewall rules to allow only required services. Stateful inspection automatically tracks established connections, so return traffic is handled without creating separate reverse direction rules for every permitted session. This reduces rule complexity, limits unnecessary lateral access, and makes troubleshooting easier when there are connection drops and various problems.

Netgate pfSense can be improved in several ways. First, I think the user interface should be clearer. Simplifying navigation and providing clearer dependency mapping between firewall rules, NAT policies, interfaces, and adding visual graphs would be helpful. I also think built-in dashboards for real-time throughput, packet drops, CPU and memory utilization, VPN tunnel health, and connection counts with configurable historical retention should be added for first-glance visibility.

Centralized monitoring would be helpful by adding more detailed historical dashboards for throughput, VPN health, CPU utilization, memory usage, configurable retention, and threshold-based alerts. With policy validation, clearer configuration differences, and one-click rollback to reduce the risk of lockout or unintended traffic disruption, this could improve the experience significantly. Version control functionality similar to GitHub would provide valuable change tracking.

I have been using Netgate pfSense for about six months.

From my experience, Netgate pfSense is quite stable. For production environments, I think monitoring CPU and memory utilization, VPN tunnel status, uptime, and failover procedures before applying changes is essential. Netgate pfSense is quite stable, and I have not faced any crashes with Netgate pfSense until now.

Netgate pfSense is scalable for small offices or remote work network environments, provided the hardware matches the workload. It supports a lot of capabilities, and scaling can involve upgrading hardware or deploying redundant firewall nodes. However, for reliable capacity planning, I would benchmark latency and connection handling under realistic traffic loads rather than solely on advertised interface speeds.

The customer support for Netgate pfSense is good, and they are capable. They have good engineers, and community forum documentation is also useful when customer support is not available. I would prefer to see support response time expectations clearly defined, and I think they should integrate AI or hire more humans to mitigate the total response time of customer support.

Previously, I relied on basic router firewall capabilities and manually configured network access controls, so I did not use an enterprise-grade solution for this. I considered Netgate pfSense for its more granular stateful firewall rules, flexible NAT configuration, and VPN support. The centralized web interface and detailed connection logs also make policy management and troubleshooting more systematic without requiring a separate commercial firewall appliance for every function.

I have seen a return on investment from using Netgate pfSense, primarily through cost avoidance and reduced administrative overhead by consolidating firewall, NAT, VPN connectivity, and VLAN segmentation into one solution. For example, consolidating traffic rules, NAT, VPN connectivity, and VLAN management into Netgate pfSense can eliminate the need to maintain multiple separate network appliances. Instead of troubleshooting connectivity across different management interfaces, an administrator can review firewall logs and connection state from one dashboard, which can save approximately one to two hours of routine administration per month, or possibly per week in a small deployment depending on complexity. I treat that figure as an illustrative estimate because I do not measure the result, but the ROI is quite noticeable.

I think Netgate pfSense is a cost-effective entry point.

I evaluated several alternatives before choosing Netgate pfSense, including OPNsense, MikroTik RouterOS, and conventional router firewall solutions. I compared them based on stateful firewall capabilities, VPN controls, configuration flexibility, hardware requirements, and the licensing cost. Netgate pfSense stood out for its integrated routing and VPN features, centralized web-based management, and its flexible deployment options alongside the availability of an affordable commercial license edition, which made it suitable for evaluating network security functionality without a large initial software licensing investment.

I rate Netgate pfSense a seven out of ten.

I give Netgate pfSense a seven out of ten because it is truly good, but every product has something to improve on. It is a reasonable rating that reflects my actual experience with Netgate pfSense. It communicates the product problems overall but still has room for improvement in usability, monitoring, and troubleshooting, and the dashboard improvement would be transformative for me. If the dashboard is improved, I would confidently give it a nine out of ten.

In my opinion, Netgate pfSense is a network security solution rather than an AI-driven security solution, and I prefer to rely on human troubleshooting rather than AI-driven security because AI can sometimes make mistakes. Its governance model benefits from explicit administrator control over firewall rules, and I would prefer AI-assisted features to remain optional and operate under least-privilege principles, with auditable decisions and human approvals for policy changes. Logs would be helpful for every AI activity.

Netgate pfSense does not provide a native general-purpose AI engine for generating security recommendations, so AI accuracy and reliability are not measured metrics. Its traditional firewall enforcement is deterministic and rule-based, making traffic decisions predictable when policies are configured correctly. For third-party AI integration, I would evaluate detection precision, false positive rates, response latency, and consistency against labeled traffic samples.

Netgate pfSense is deployed in my organization as a private cloud on a local server.

My advice for others looking to use Netgate pfSense is to start by testing it in a lab or a virtual machine. Running a virtual machine to deploy it before production deployment is affordable. Define the requirements for throughput, concurrent connections, VPN encryption, VLAN segmentation, and high availability, then size the hardware accordingly. Document firewall and NAT rules, apply least privilege access policies, and maintain tested configuration backups. Monitor CPU, memory, interface errors, and connection states under realistic traffic loads. Finally, test recovery and failover procedures to ensure that a configuration error or hardware failure does not cause an extended outage.

The main use case for Netgate pfSense is to set up VPN servers in the cloud. I set up VPN servers in the cloud for clients, and then connect the clients' NAS devices and employees' PCs to those servers. We can use a static IP address, so we can provide static-IP access for customers who need access restrictions.

Netgate pfSense has had a significant impact on my company as we mainly used it to build VPN environments for our customers, and it made it very easy to understand each employee's VPN usage status.

The specific metrics and results I obtained include data transfer volume, and since we can see traffic per individual, it became easier to identify issues such as whether someone might be watching videos.

The best feature of Netgate pfSense is that it supports almost all VPN protocols, and it can issue certificates to each user.

A situation where the certificate issuing and protocol support were particularly convenient is that recently we often switch from OpenVPN to WireGuard, and since we can issue certificates to each individual user at that time, it is very easy to use.

Regarding Netgate pfSense's governance features, we can see everyone's traffic volume, so we can set rules to limit excessive use by imposing transfer limits, and I think that part is valuable.

One area where Netgate pfSense could be improved is that there are not many plugins for two-factor authentication.

Although plugins for two-factor authentication exist, the problem is that we have to use external services such as Deffsense, Tailscale, or Headscale.

Regarding processing robustness and reliability, I think it is still not as advanced as Claude, so for now I am still using Claude to configure Netgate pfSense.

I have been using Netgate pfSense for approximately one year.

Netgate pfSense has very high stability; the server has never gone down, and there are not many updates, so the level of completeness is quite high.

Regarding the scalability of Netgate pfSense, we have not tested scalability yet. For now, one unit is sufficient, so I cannot provide detailed information about scalability.

Before Netgate pfSense, we used SoftEther, but with SoftEther alone there were various failures, so we switched to Netgate pfSense.

I evaluate specific metrics and ROI by noting that our clients have become almost fully remote, so in the sense that they would not have been able to go fully remote without this investment, the ROI is almost close to 100%, definitely over 90%.

My experience with pricing, implementation costs, and licensing is that the implementation cost was difficult at first and was a bit high. However, by using AI support such as Claude, we were able to implement it relatively easily.

We also considered OPNsense before choosing Netgate pfSense, but the implementation cost was a bit high at the time of deployment, so we used Netgate pfSense instead.

My advice to others considering implementing Netgate pfSense is that if you want to implement two-factor authentication, OPNsense has more plugins available, so that might be easier, but it is possible to implement two-factor authentication with Netgate pfSense as well.

I would rate Netgate pfSense about 7 out of 10. The reasons I give it that score are first, ease of use, and also the richness of features; the reason the score is not higher is that two-factor authentication is difficult.

I use Netgate pfSense as a gateway device, where I manage network security, routing, VPN, and traffic management. I'm using the firewall for user authentication as a multi-WAN, or SD-WAN, and all those things are mainly used by the firewall only.

Netgate pfSense has positively impacted my organization because before Netgate pfSense, we were using a router for NATting and various tools for security management. Now, I can do all those things via the firewall only, which has helped me considerably, and all things are shown on a single dashboard.

The best features Netgate pfSense offers in my experience are its firewalling and NAT. In firewalling, stateful packet inspection as well as advanced NAT are used. VPN support is also excellent, with IPsec, OpenVPN, and WireGuard all supported. For load balancing, failover, and SD-WAN, it is being used, and the best aspect is about its security services, for example, IDS, IPS, DNS filtering, and GeoIP blocking.

Vendor backend support must be improved and customer support can be improved. I would like to see improvements in VPN for Netgate pfSense because sometimes the CPU shows heavy load, configuration is a little bit complex for OpenVPN, and troubleshooting is the main concern.

You could add AI for troubleshooting with Netgate pfSense because it will be easier for new engineers.

I have been using Netgate pfSense for the last two years.

Netgate pfSense is stable in my experience.

Netgate pfSense's scalability is strong but conditionally for stability models. It has no hard-coded limits.

The customer support for Netgate pfSense can be improved. I do not say it is bad, but it can be better.

I was not satisfied with the firewall I previously used before Netgate pfSense.

My experience with pricing, setup cost, and licensing for Netgate pfSense is that the pricing is good compared to other vendors, but licensing can be improved as it is a little bit confusing.

We work as a partner with this vendor, not just as a customer.

I have seen a return on investment with Netgate pfSense because it helped me in all these areas.

My experience with pricing, setup cost, and licensing for Netgate pfSense is that the pricing is good compared to other vendors, but licensing can be improved as it is a little bit confusing.

I have not evaluated other options before choosing Netgate pfSense.

I rely on VPN the most in my daily operations because many of my users are working from home, so I provide the RA VPN to the users for remotely accessing my servers that are placed inside my internal network.

I definitely advise others to use this firewall device, as it is truly useful, time-saving, and money-saving. My overall rating for Netgate pfSense is eight out of ten.
