Earlier people were only bothered with online privacy but the recent spate of cyber attacks have forced us to also look after our offline privacy. With the latest technology advancing in leaps and bounds cyber criminals have got hold of very sophisticated cyber tools and programs which are capable of attacking your computer even when you are offline. Here’s a list of five best free firewall programs for Windows 10 to help you keep those threats at bay.

 What is a Firewall Program?

Most best internet security suites come with in-built tools to check a whole range of suspicious activities. However, it is always a good idea to provide your computer with the best possible security. This is where the firewall program comes in. Firewalls are very effective network security programs which monitor incoming as well as outgoing network traffic at the gateway server and prevent any unauthorized access of your system or network. It never hurts anyone to invest in a decent firewall for their system or home network especially when it comes completely free. Here’s a list of the five best free firewall programs for Windows 10.

ZoneAlarm Free Firewall

Back in the day when the internet was a tad less crowded and Microsoft users had to deal with endless cyber attacks one program came to the rescue. The application which introduced us to firewalls and was a must have in the old days of lax internet security is available for your Windows 10 and that too free of cost. The ZoneAlarm Firewall has been in business for a long time and here’s why.

A new version of this popular firewall program can hide open ports, detect potentially threatening traffic and shut down malicious programs. It even connects with DefenseNet to provide the user with real time security updates whenever a new threat is detected. The user can also manually list any harmful website or suspicious URL or program to the list to allow or deny access. There are two modes- Auto Learn and Max Security. While Auto Learn mode studies the user’s behavior pattern and network traffic to make adjustments, the Max Security mode gives the user full control of the firewall. Quite the handy program it works on Windows XP, Vista, 7, 8 and 10.

PeerBlock firewall

Now here’s a firewall program designed to address specific needs.
