Software firewalls are an essential part of your online safety. They protect your computer and network from incoming malicious attacks and viruses and give you an extra layer of protection on top of the firewalls that come pre-installed on your operating system.

While you may already know that your operating system—whether it’s Windows or Apple—provides firewall protection, you might not know enough about what it does and does not protect you from. So, let’s look at firewalls: what they do, what they don’t do, and which ones are the best for your individual needs.

How does a software firewall work?

A software firewall is a type of filter that is meant to protect your computer from threatening communications. To enable seamless operation of your computer and devices, it allows some types of data to get through but not others. It blocks what it thinks is malicious activity by recognizing known patterns, in other words, it leverages what is already known about certain threats to protect your systems.

A software firewall comes with pre-set guidelines that can be further modified to suit your needs – to a degree. Free or “included” software firewalls are fairly limited in scope and if you are concerned, you might want to think about adding another one or upgrading to a more advanced “premium” version.

The firewall protection you already have

Software firewalls are a component of your computer’s operating system. It is also part of your ISPs configuration – meaning that your internet service provider includes a firewall in your package. These firewalls are part of your router hardware and control incoming connections to your computer and other devices on your network. Both software and hardware firewalls can be customized according to your personal preferences.

 

Your software firewall should:

  • Stand as a sentry between the internet and all devices on your network
  • Block incoming malicious activity
  • Notify you when you are visiting potentially harmful websites
  • Provide a stealth-mode that makes you invisible to hackers
  • Disable malicious programs

The software firewall roundup

These are just a handful of software firewalls that you might choose. With today’s advances in internet security and the robust nature of the protections that come included with your device hardware, the demand is relatively low, so the best examples offer extended features and functionality to round out their portfolio.

 

ZoneAlarm is a highly rated, affordable firewall, but is not compatible with Mac. Comodo has many aficionados, though it is inconsistent in detecting malware and if you use the free version you’ll constantly be pestered with upsell messaging. Kaspersky is a great all-around internet protection suite that offers a lot of advanced features but some report that it can slow down your computer’s performance. Lastly, Glassdoor represents next-generation firewall technology, giving you robust protection along with a complete and transparent view of what your computer is doing at all times.
