Top FREE Personal Firewalls for Your System’s Protection

Windows XP systems already have a built-in firewall software but is not a complete firewall product and also lacks many advanced features that a dedicated firewall software has. Mentioned below are some popular personal firewall software products that are full of important features and serve the purpose of having a dedicated firewall software.

1. [ZoneAlarm] - Very easy to use, updates automatically from the ZoneAlarm’s website for latest security patterns and software updates. I personally use it and am very happy with it. No matter if you have a stand alone system connecting to Internet or WiFi or VPN, a personal firewall software such as ZoneAlarm is a must.

2. [Comodo] - This free version is not a strip down version of a full featured product but a complete product with free lifetime license. The company which produces this product claims it to be the only firewall that does not leak. The interface is very easy to use and impressive.

3. [Sunbelt Kerio Personal Firewall] - This one is another free yet powerful personal firewall software and is actually a replacement of Sygate personal firewall software. It works as a full product for first 30 days and post which it will keep running as a free product but with limited features. With a free version of this product, some of the important features that you will miss after 30 days are - Host-based Intrusion Prevention System, Identity Theft Protection, Script blocking and Ad blocking.

4. [OUTPOST Free Firewall] - It’s an agnitum product which also offers a PRO version of the same product. The free version offers basic firewall capabilities such as packet and application filtering, maintaining privacy on Internet. It’s best suitable for people who do not visit Internet very often.

Conclusion: Irrespective of whichever personal firewall software you choose, ensure that it has more number of features and receives patches and updates free of cost.
