The solution provides combined firewall, VPN, and router functionality, and can be deployed through the cloud (AWS or Azure), or on-premises with a Netgate appliance. It as scalable capacities, with functionality for SMBs. As a firewall, pfSense offers Stateful packet inspection, concurrent…
As an edge/WAN router that contains internet BGP routes, it handles this work very well. And the devices are robust, able to manage a significant load. However, the interface cost can be somewhat of a hindrance when wanting to use it to interconnect many metro clients.
Because pfSense is built around open source software, it is very convenient to be able to deploy in the event of hardware failure. We once had a client with a proprietary router that failed. While the router was under warranty, the expected time for the new router to arrive was about 2 weeks. We decided to implement pfSense for the client as a stop gap and ultimately ended up deploying the full enterprise appliance. Being able to get up and running using commodity hardware was a huge win for the client. We've also had a great amount of success deploying pfSense hardware at apartment complexes. The DNS resolver works great and we've had no issues handling multiple VLANs with various DHCP scopes on it. Finally, we've had clients that require having a failover cluster. Utilizing the built in CARP capabilities, we've been able to provide a very robust failover system that requires little maintenance and no downtime in the event of equipment failure.
Easy to use. Good user interface design! Easy to understand and easy to set up.
Lower hardware requirement. 3 years ago, we used an old PC to run it. Now, we have changed to a router device with Celeron CPU and 8GB RAM. It runs smoothly with a 1000G commercial broadband.
I would like to able to find more examples of configs. Given the multiple ways to configure the same setting, having a little more documentation would be helpful.
I did kind of mention a Con in the Pro section with OpenVPN.
When I create a config for an employee other employees are able to login to that config.
I could be doing something wrong when I am making it - I am not afraid to admit that as I am pretty new to all of this, but it seems like it builds a key and I would think the key would be unique in some way to each employee, but I could be wrong.
I actually do not have a lot of Con's for this software - I did not get to set this up on our work network so I am not sure of any downfalls when installing.
I installed this on my personal machine in a Hyper-V environment to get a feel for it before I started working on it at work and it seemed pretty smooth. I didn't run into any issues.
Juniper (Junos) and interoperability. Junos is so powerful as a troubleshooting tool and also as a configuration tool. We had test and roll back configurations which is very helpful. Being able to link to over vendors equipment and extend features is very nice to have.
Juniper support is friendly, easy to understand, widely knowledgeable, and easy to get ahold of. I did not give them a higher rating as some of my more complex issues, were solved by myself while under consultation from Juniper TAC.
Juniper Enterprise Routers are know to be the backbone router of choice for the internet. They are also very well known for Junos OS which make they easy to manage, confiture and troubleshoot.
While you can get the performance out of other products, pfSense offers the unique ability to put other services on the same device. Products such as Untagle's NG Firewall and SonicWall's TZ series offer cost effective options for firewall and VPN services, having incoming load balancing and connection proxies on the same device as the firewall offers extremely easy configuration and day to day management of network services
The stability and robustness of this solution provide a rock-solid foundation for all of our internet traffic.
The easy to use rollback and commit features simplifies remote administration and configuration, alleviating the need to travel to remote installation sites.
Using pfSense has allowed us to build a professional network in our small office without needing a lot of proprietary hardware, saving thousands of dollars in IT infrastructure investment.
The cost for using pfSense is free, so it's a great option for those who don't have a large IT budget
pfSense utilizes all of the industry standard services to provide all of it's functionality, so support for service-level issues is readily available
Because of how much work has been put into pfSense to make it rock solid and reliable, we're able to support our network with minimal IT staffing, saving us thousands of dollars/year in personnel alone.
