The best firewalls for Mac 2021 - test and comparison

A common myth is that that Macs don't need a firewall or antivirus solutionbecause there are simply no security gaps. However, this is a mistake. Over the past 3 years, the number of malware and other Mac malware identified has increased rapidly. Probably because most Mac users don't protect their devices with firewalls or antivirus software.

Now MacOS has one integrated firewallwhich is deactivated by default. This should definitely be activated (we'll show you how), but it doesn't necessarily offer sufficient protection.

If you want to be on the safe side, you should install a firewall for Mac. Most internet security vendors have one too special Mac version on offer. We have tested the best firewalls for Mac and compare them here.

    What is a firewall?

    A firewall is a system that allows the unauthorized access to or from a private network. A firewall can be set up in either hardware or software, or a combination of both. In this post we will focus on software solutions.

    Firewalls prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. A firewall must offer two protective functions:

    • For one thing, it has to prevent that unauthorized access from the network can be done on your device.
    • It must also be ensured that no programs or software without permission from your device on the Internet accesses or communicates via this.

    "Apple Firewall" - the pre-installed Mac firewall

    Apple has integrated its own firewall into its macOS operating system. For reasons that are not apparent to us, however, this is disabled by default. Because the firewall protects against unauthorized access to the PC on the network, you should activate it in any case. It works like this:

    1. Go to the Apple menu and click the “System Settings".
    2. Select the option "Safety".
    3. Now click on the tab "Firewall".
    4. Now you have to use administrator rights activate the setting options. To unlock, click the To unlock, click the lock in the lower left corner. Now enter the user data for the administrator account.
    5. Select the button "Deactivate the firewall"And then click on" Start ". The firewall is now activated.

    Optionally you have under the point "More options“The ability to configure the exact settings of the firewall.

    Why a firewall is required for Mac

    Although malware is much less common on Mac devices compared to Windows, there are malware threats to your Mac. This is most evident in the number of Mac malware pests and so-called potentially unwanted applications ("PUA" - potentially unwanted applications).

    The renowned independent Industry institute AV-Test reports that detected Mac malware threats increased from just 5.227 annually to a whopping 28.922 in 2017 and a staggering 94.024 in 2018. Even if the number for 2019 fell to 59.847, 2020 malware threats for Macs have already been counted in 11.549. So I have to come back for this year with an increase be expected.

    The picture is somewhat different for PUAs. While it was 2018 in 79.068, this fell to 2019 PUAs for MacOS in 52.229. For 2020, however, there are signs again rapid increase from: By April 21, 2020 alone, 21.590 PUAs were identified.

    What do these numbers mean? Well, two things:

    Indeed there is tens of thousands of malware threats and pestswho want to find their way onto your macOS device. Therefore, you should absolutely protect your device and your data. An external firewall also helps here.

    As mentioned at the beginning, an effective firewall takes over the monitoring of all attempted, incoming access to your device from the network, as well as the programs on your PC that want to communicate via the Internet. The internal firewall MacOS only takes on the former task. It avoids unauthorized access from the Internet.

    • However, so that you can prevent programs from unauthorized (otherwise unnoticed by you) access to the Internet, you must have a special firewall for Mac to install.

    What to look for when choosing a firewall for Mac

    So that you can find the right firewall for Mac, you should take these criteria to heart when selecting and comparing providers.
