IPFire Alternatives: Similar Firewalls and VPN

You need to protect your assets, any network laid bare without a sound security setup is open for intrusions. Two of the few essentials you must already be working with are firewall and VPN setups.

A firewall as the name suggests serves as a barrier that protects your network from untrusted networks. To better explain it look at this definition:

"A firewall is a network security device or mechanism that allows for the monitoring and filtering of inbound and outgoing network traffic that is based on an established and well-defined set of security protocols or rules."

In simpler terms, a firewall helps block unwanted traffic from entering your network and protects it against malicious software that could infect your computer. Think of it as a traffic controller of sorts that allows certain traffic to pass through and blocks other malicious network traffic. The operating system you are using on your PC comes with a pre-installed firewall, you should make sure you have your firewall on and updated at all times.

The next must-have when it comes to engaging in safe computer and internet usage is installing a VPN.

VPN standard for "virtual private network", usually defined as:

"A VPN can be thought of as an encrypted or in simpler terms a private connection over the internet from one device to a network. VPNs allow for the establishment of protected network connection when using public networks."

To put it in simple terms, A VPN helps hide your online activity, it shields you against hackers on public networks, hides your IP address, physical location, and browsing activity on any WI-Fi network. No one can tell who you are, where you are located, and what you're looking up online.

When it comes to network security you may invest in costly firewall setups and VPN but some services are available for free. One such incredible service is the IPFire distribution.

IPFire is an open-source Linux distribution specifically catering to the tasks of firewalls. Open Source means that yes, it is free to be used and distributed by users all around the world. Unlike other distributions, IPFire is hardened and optimized for use as a firewall. It assists in intrusion detection, VPN, virus scanning, URL filters, and fulfills all the primary security objectives.

Not only is it easy to configure and easy to use but it is a great solution geared to prevent attackers from accessing your network. Here we will be discussing some firewalls and VPNs that are quite similar to IPFire and can be used as an alternative. Read on for some incredible finds!

What Should Be Considered While Choosing IpFire Alternatives?

As a rule of thumb, there are certain features you should be looking for when choosing an IPFire alternative, these can vary according to your network requirements but should never be neglected.

  • Easy to navigate UI: Not all of us carry the technical expertise needed to navigate high-end firewall and network security solutions, this is why you should generally prefer solutions that carry a uniquely designed, easy-to-use user interface.
  • Visibility and control: The deeper visibility you have into your network, the better control you have over its security. Traditional firewalls usually carry limited control and visibility across end users on your network. The right firewall solution should provide you with better accessibility.
  • Other Capabilities: The solution you choose to acquire should also be able to provide you with non-firewall-linked capabilities. Some essentials you should look out for include VPN implementation, packet filtering, proxy server, bandwidth optimization among others.

What is Better than IPFire?

Both OPNsense and pfSense® software have always been seen as reliable competitors across IPFire. All solutions are geared with nearly similar features and provide you with robust firewall and VPN implementation across your network. However, OPNsense and pfSense® software carry some features that are rarely available in modern professional firewalls giving it a slight edge over IpFire. When these FreeBSD based platforms are powered with the next-generation firewall capabilities of Zenarmor, there is a significant difference between them and IPFire in terms of security. Zenarmor provides great security features that IPFire can not offer. You can easily install Zenarmor your OPNsense or pfSense® software firewall and start to get benefits of its protection for safeguarding your valuable assets.

Comparatively, OPNsense and pfSense® software may seem a bit more technical to configure and set up but are great at security optimization and reporting. However, keep in mind that they are both free and open-source for use and distribution. While many may prefer IPfire owing to its simple UI, OPNsense and pfSense® software with Zenarmor are best alternative you simply cannot ignore.
