Review article: 

Best Free Firewall - Basic


Built in to Windows, no separate installation needed, simple and easy to use, effective, passes all tests, no nagging or annoying pop ups, runs seamlessly and quietly in the background, significant improvements since initial version in XP. Likely suitable for most day to day use.

Product type: 

Runs as a stand-alone program on a user's computer


Primarily incoming connecting protection only. Advanced user interface is not user friend - this interface may not be suitable for beginner users. Would be very beneficial complemented by a third party tool such as Windows10 Firewall Control. Windows XP's version is very basic and lacks any outgoing protection. May not provide adequate protection for "high risk" users
