Simplewall Review
Simplewall is a firewall program that monitors incoming and outgoing network activity, thus allowing you to create rules and blocklists for all programs that want to connect to the internet. It is configured to automatically block malware and telemetry-related data, but can also include custom rules.
As a freeware application, it doesn't require any form of external advertising, making it an ideal choice for users that prefer privacy over functionality. It works on all Windows platforms and can be installed in just a few seconds. Its hardware requirements are modest and it consumes a minimal amount of system resources.
This program has a simple and compact user interface that lists all applications that are trying to connect to the internet. You can check the boxes corresponding to each application to add it to the relevant list. Once everything is configured, nothing can connect to the Internet without your permission. You will get a lot of prompts at first, but once you've dealt with them, they will stop occurring.
Simplewall is a great program to use in conjunction with Windows Firewall control features. It is effortless to install and highly effective, although the in-app usability could be improved a bit. It also works as a portable program, meaning that it can be run from a USB flash drive. This makes it easy to carry with you anywhere you go and use on any computer. You can even set up a portable firewall on your mobile phone to protect it against unwanted connections.
