Why Use Pfsense? Security Software Strategies

We are all aware that Pfsense is an open-source firewall and router that has been around for over a decade. It was initially designed to be used as a personal firewall on desktop computers, but it’s been adopted by many businesses as well. Pfsense has made headlines recently due to its security features and the fact that it is incredibly affordable. This blog post will explore why pfsense is such a popular choice among different types of companies!

What is Pfsense?

Pfsense is a free firewall and router that was initially designed to be used on desktops. Many businesses have since adopted it in their networks, cloud environments, or even physical servers. Some popular pfsense applications include using it as an OpenVPN server or a captive portal for your business networks! Pfsense can run on a variety of hardware, including x86 based embedded systems.

Why Should I Use Pfsense?

There are several reasons that companies should consider switching to Pfsense. These include:


One of the most popular reasons for using Pfsense is because it’s open-source software which means you can install and run it on your servers without paying anyone else any additional fees.

Security Features 

There are numerous built-in security features within the core code of Pfsense, including UTM (unified threat management) through its use of Snort pre-installed with IPS functionality. This provides businesses with various benefits from stopping viruses from ever reaching customer computers or devices, allowing admins to protect their network against spam covering all email protocols, and providing powerful anti-virus, anti-spyware and content filtering functionality.


Because Pfsense is open source software, it can be installed on various platforms, including physical servers or cloud environments. This means that if you need more resources for your network to handle an increase in traffic or users, many companies can help you scale up quickly without investing in expensive hardware upgrades.


Because Pfsense is open source, many companies specialize in providing support for it. This means that if you ever have any issues, help will be available quickly and efficiently, which isn’t always the case when using proprietary software.

Why Should I Use Pfsense?

As mentioned previously, pfsense provides solid security features at no additional cost, making it very appealing when tight budgets. For example, most businesses today have internet-based applications such as VoIP calls where important data could potentially be intercepted by hackers or malware programs. However, one of the most potent aspects of pfsense allows it to act as a VPN client that encrypts all traffic before sending it out across the internet, which means you can rest assured knowing your calls are secure.

Another benefit is its compatibility with other open-source software packages, so if you have an existing system in place for things like authentication, then there’s no need to worry! pfsense works seamlessly with many different types of databases and applications, making it easy for admins to install any additional features they might require without making extensive modifications on their end.

Who Uses Pfsense?

Businesses can use Pfsense in a variety of industries, including:

Education And Schools

Pfsense is extremely popular with universities because it has features such as a captive portal which allows students to log in to the school network easily. It also helps keep networks safe from viruses and malware!


Energy companies are always looking for ways to maximize their resources while maintaining efficiency, security, and availability at all times. pfsense can help them do this by monitoring outages quickly through its reporting tools that allow managers to troubleshoot issues before they escalate into serious problems or emergencies!

Gaming Servers 

No matter what type of business you run, you likely have an online presence these days! This means that gaming communities are becoming more critical to companies in every industry. pfsense provides gamers with powerful tools such as GeoIP blocking, allowing admins to ban users not within their region from accessing the game servers.

Internet Service Providers (ISPs) 

The network infrastructure of ISPs can be complicated because they manage so many different types of services for customers, including residential internet access and VoIP calls. Maintaining security across this expansive environment while keeping costs down is helpful if your ISP uses pfsense. It gives them a layer of protection against attacks by hackers or malware infections on customer devices connected directly to the router itself!

What Are Some Features Included In Pfsense?

Some of the many features available with pfsense include:

A Captive Portal 

This allows admins to set up websites, custom login screens, and even access times for users who want to connect wireless or wired through ports. This is especially useful for organizations that need to keep track of user activity.

Network Failover Support 

When you have redundant connections between networks, it’s essential they do not become overwhelmed by traffic volume! With network failover support on pfsense, any internet connection can be used as a backup plan if another one fails, so business continuity never takes a hit.

Load Balancing Across Multiple WANs 

Because there are no specific rules related to bandwidth management, pfsense can help you spread traffic across multiple connections, increasing the efficiency of your internet service.

What Are The Limitations Of Using Pfsense?

While there is no denying that pfsense provides many benefits to companies looking for powerful, affordable network security software, it’s important to note some of its limitations as well. For example :

  • GeoIP blocking means you have more control over who can access your online presence. Still, it has limited functionality when trying to stop someone from accessing a specific site or service. This type of content filtering technology simply cannot replace traditional web filters that only allow users on particular computers within an organization past policies set by admins.
  • For best results with gaming servers, the computer running pfsense should be located nearby so all user information can easily be tracked and blocked without causing additional latency.
  • There are also certain limitations with pfsense, which prevent it from being used on cloud-based platforms or virtual machines, so admins will need access to their server for the software to work correctly. Without this, they would not install any additional features required by specific applications within an organization.

Frequently Asked Questions (FAQs)

Q. Where can I download pfsense?

Pfsense is available for download from the official Pfsense website. There are several different versions to choose from depending on what your needs may be, including:

  • Giant: an all-inclusive image that includes every package in the software repository and should work out of the box with most hardware configurations. This is perfect if you want to get started quickly without having to add anything additional.
  • Standard: similar to Giant, but it allows admins more control over specific features included by default, such as web filtering or antivirus/antimalware options, etc.
  • Nano: this version simply contains only essential functionality while saving space since RAM resources won’t needlessly be allocated towards programs that aren’t needed at startup. However, it also means admins will need to add any additional features they might want later on through the package manager.

Q. How much memory does pfsense require?

To run pfsense, you may need at least 512 megs of RAM, but in reality, this is only a minimum if your network needs are fundamental. For example:

If you plan to host web servers or use an advanced firewall and filtering options beyond simple URL blocking, then more than recommended would be necessary for optimal performance…etc., etc. It’s important to note that some hardware configurations simply won’t work with specific versions, so always check compatibility first before installing new equipment!

Q. What other operating systems can run pfsense?

Even though most people will use this software with Linux servers or Chromebooks, pfSense works on almost any device with enough RAM to support it! If you have a spare PC sitting in your garage, then feel free to install it yourself instead of purchasing new hardware if necessary. It should also be noted that FreeBSD (the foundation it’s built on) is compatible with even more devices.
