3 Best Firewall Apps for Mac OS (2023) – Free & Paid

Rate this post

There is a common belief it is true that Macs do not require an antivirus or firewall since there aren’t any security holes. This is, however, an error. In the past three years, the number of viruses and Mac malware detected has increased dramatically because Mac users do not protect themselves from malware with firewalls or antivirus software.

The moment is that MacOS comes with a built-in firewall, which is turned off by default. It should be activated (we’ll explain how); However, it’s not necessarily enough security.

A firewall is an arrangement that is designed to block unauthorized access to and within private networks. It is possible to implement a firewall in either a software or hardware form or a combination of both. Firewalls can block unauthorized Internet users from using private networks linked to the Internet.

If you’d like to be sure, you must install a firewall on your Mac. The majority of security companies offer a specific Mac version that they offer. We’ve tested the top best firewalls available for Mac and compared the results here.

1. Little Snitch

Little Snitch

While there are fewer malware threats to Mac systems, there’s an urgent need for data security. Through Little Snitch for Mac, users can block personal information from being released, but its limited features could prove to be not worth the cost.

The Little Snitch application for Mac is available to try at no cost for 30 days. After this, $29.95 buys the full version, with no limitations. Although it comes with an installation program that is native, loading the program was difficult as it required restarting to function. A lengthy and complex user agreement was also required to be signed. Support for technical issues and updates are available. However, the program has no clear instructions on how to use it. Although advanced users will not likely have issues in this regard, complex permissions required to customize the program might be too difficult for beginners.

The program needs little involvement and runs in the background as far as function. After setting defaults, it scans the user’s system for applications that transmit data. This cannot be assessed because we didn’t find any applications that attempted to accomplish this, even though the program said it was running. Although this may sound similar to firewalls, the application declares itself a privacy program and not an all-encompassing security application.

2. Radio Silence

Radio Silence

Radio Silence is a tiny firewall that blocks any program from accessing the Internet. It is specifically designed for those who do not have the time to setting up traditional firewalls. Radio Silence supports OS X Yosemite, Mavericks, Mountain Lion, Lion, and Snow Leopard. It takes only some minutes to install.

Radio Silence lets you disable outgoing access for any application you’d like. We like it because it is maintenance-free and is always online. However, it monitors every connection you have in real-time, which means that all secret processes will instantly be exposed. The application will also not require your consent. This could make your computer vulnerable.

The radio silence option is very easy to use. It doesn’t require a lot of space and is extremely rapid. Additionally, it’s incredibly user-friendly, which means you don’t need to be a tech expert to set it up. However, to gain access to all functions, you’ll have to shell out $9.
