What Are Software Firewalls?

Software firewalls are applications that you install on your device. Operating systems come with built-in software firewalls. There is a Linux firewall, Mac firewall, Windows firewall, and Ubuntu firewall. The latest version of Windows OS comes with Windows 10 firewall. While Android doesn’t have a native firewall, many Android firewall options are available for download. Third-party software firewalls can also be installed on other OSes as well.

Equipped with more advanced features, software firewalls provide greater granularity of control. They can filter all traffic, including encrypted ones like HTTPS. These firewalls analyze data based on content including keywords.

Outside operating systems, software firewalls come as a built-in feature among third-party applications known as Internet security suites. Apart from integrating a software firewall, these Internet security suites come with other features like antivirus or antimalware, quarantine, and safe browsing for online banking and shopping.

Why Do You Need A Software Firewall?

While operating systems like Microsoft Windows and Apple macOS come with an integrated software firewall, you’ll still need a software firewall as a component of an Internet security suite. Windows Firewall and macOS application firewall work well as a software firewall but has the same limitations as a standalone hardware firewall solution.

Installing a third-party software firewall that comes as part of an Internet security suite with a built-in antimalware feature remains crucial in spite of the effectiveness of a built-in operating system firewall as a firewall solution. Internet security suites can stop and remove viruses and other types of malware like worms, trojan horses, spyware, and adware.

Things To Consider When Buying/Choosing A Software Firewall

If you are buying a software firewall as a homeowner or a network administrator of a company’s IT department, there are pointers and features that you should take into account before arriving at a decision and spending money.


Your security software must be equipped with a sophisticated scanning engine that can guard your devices against the latest malicious threats and different types of malware like rootkits, trojans, spyware, and viruses.

File Encryption

As your personal files and information are the most valuable things stored on your device, your Internet security software suite must have a feature that allows you to encrypt them. Encryption prevents unauthorized access and data theft.

Multi-device, Multi-OS 

Today, Internet security suites have variants that can support up to ten different devices, popular consumer Internet browsers, and different operating systems. Choosing the right one ensures 100% security, whether you are on a desktop or a mobile device.

Sandbox Technology

In computer security, a sandbox serves as a software testing environment where you can browse the Internet and run programs without the risk of them changing and potentially infecting the system.

Secure Online Banking & Shopping

Because online banking and shopping have become a common activity on the Internet, your security software should have a feature that protects you when doing financial transactions online. Your software firewall should be able to block fake websites.

Optional Firewall Activation

As operating systems like Windows and macOS already come with a built-in software firewall, you must have an option to activate/deactivate the third-party software firewall of your Internet security suite. Running two software firewalls may slow down your device.

Performance Optimization

Apart from not slowing down your device, your security suite must include features that allow you to keep it running smooth and snappy. Not only focusing on the entire operating system, but it also includes individual applications and your Internet browsing experience.

Aftersales Support

While these security applications are easy to use, some users might have additional concerns or are unfamiliar with running them. The companies behind these programs must have adequate aftersales support through FAQs, documentation, and technical support staff.

Reasonable Price

The last but not least, price is always a factor when it comes to choosing the right software firewall and Internet security solution. It’s important that you think about not only how much something costs but how it will fit into your budget.
