Rapid VPN setup has connected offices in minutes and brings live insights for proactive issue control
What I appreciate the most about Netgate pfSense is the ease and straightforward nature of the platform. I can set up a new office in less than 10 minutes. The benefits of using Netgate pfSense are that I can set up VPNs in less than two to three minutes, and then just deploy the file across my networks, where everybody would be connected in less than an hour. The dashboards of Netgate pfSense bring all the necessary information that I need at a glance, and it is actually a live update every three to five seconds. It is spotless, and I have been able to catch issues before they hit operations.

User has benefited from stable performance and effective completion of security tasks
I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of pfSense are the pfBlocker, HAProxy, NAT, and VPN."
"The most valuable features of pfSense are the high availability that easily allows failover to a backup unit and the Snort integration with pfSense and WireGuard."
"We have pfSense across three sites where it manages the VPN and firewalls between them, has reduced costs drastically, and has outperformed its expectations."
"The features I've found most valuable are proxy server (to filter traffic, act as intermediary between our server and our client, and analyze and load-balance traffic), load balancer (support multiple servers, load balances two gateways on the same tier), and hot spot (with captive portal, forces authentication or click-through for network access)."
"The plugins or add-ons are most valuable. Sometimes, they are free of charge, and sometimes, you have to pay for them, but you can purchase or download very valuable plugins or add-ons to perform internal testing of your network and simulate a denial-of-service attack or whichever attack you want to simulate. You can also remote and monitor your network and see where the gap is. Did you forget a printer port? Most attacks at the moment are happening through printers, and they can tell you immediately that you forgot to close the port of the printer. There are more than one million printers that are in danger, and everybody knows that hackers are using them to enter the network. So, you can download plugins to protect your network."
"The intuitiveness and ease of use are the most valuable features of pfSense."
"It's a good product, and it really could be a valid firewall solution."
"The classic features such as content inspection, content protection, and the application-level firewall, are the most important."
"The solution can scale well."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The cost is very low."
 

Cons

"It was difficult to configure our web printer through the solution. This process could be easier. Additionally, integration with SD-WAN solution."
"Their support could be better in terms of the response time."
"Their UI could have hidden some of the complexity better so that it was easy to understand or more general. They could have given some more clarification on the markings on the outside of the machine."
"Layer 7 advanced firewall features are not included in the solution."
"As per my understanding VPN, Captive Portal user-level and MAC-level filtering need to be improved."
"I want pfSense to add some next-generation firewall features."
"If we had, for example, ten pfSense routers deployed, it would be nice to have one console where you could see all ten devices, update the, and keep them all central. A management portal would be very nice."
"The solution’s interface must be improved."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"The product has some scalability and data management issues where improvements are required."
"Sometimes it reboots when you least expect it, and that's the main issue."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
 

Pricing and Cost Advice

"It's open source (and free - as in beer and speech), but also has commercial support."
"It is about €1,000. It is a one-time payment. I do not have a monthly or yearly subscription. I don't subscribe to any subscription because I hate cloud services. There are no additional costs."
"All costs are low compared to other solutions. The hardware is stable and cheap."
"There is an open-source community version that is available."
"Netgate pfSense stands out as a cost-effective option that delivers excellent value."
"There is no license. You don't have to pay anything. It's completely free."
"PFSENSE turns out to be very economical, the license is free and for little money you get very good support"
"I would recommend it for a small business or a startup as a starting point. It's also good for companies that are on a tight budget."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
