Ever wished to cease a selected app from going surfing—whether or not to guard your privateness or block suspicious exercise? Me too—and that’s why I exploit Portmaster, a free, open-source community monitor that allows you to see each connection your apps make and blocks something you don’t belief with a single toggle.
Find out how to immediately cease any app from going surfing
To dam an app from web entry, merely open the Portmaster app, and the left-hand sidebar will present you all operating apps and providers which can be presently related to the web. Click on the app you wish to block—say, Google Chrome—and toggle Block Connections. It’s that easy!
Portmaster integrates straight into your system’s community stack, which permits it to see—and present you—each incoming and outgoing connection on a per-app foundation. This implies you’ll be able to see precisely what every app is doing on-line and cease it if it’s essential to.
Portmaster merely screens, logs, and blocks incoming and outgoing connections. It doesn’t examine each incoming and outgoing packet. For that, you’d want a packet-inspector like Wireshark—however these instruments may be too technical and overcomplicated for easy house customers.
Why I wish to block sure apps from accessing the web
I set up lots of totally different apps and instruments on my PC for testing and experimentation—it comes with the job—and as you’ll be able to think about, this additionally exposes me to potential cyber threats. I may unintentionally set up one thing malicious that Windows Defender could not detect, and now it is quietly stealing my information within the background.
For instance, I really like utilizing Obsidian to retailer all my private notes as a result of it really works offline and regionally shops all the pieces. Nonetheless, I additionally use Obsidian plugins so as to add further options to the app. These are community-built, and Obsidian explicitly advises customers to put in them at their very own danger.
Whilst you can learn the supply code of those plugins to confirm whether or not they’re malicious or not, I am not an skilled programmer and do not know methods to audit code. So as a substitute, I merely block Obsidian from web entry altogether. This fashion, even when a plugin is malicious and tries to telephone house, it may well’t!
When there is a new replace for Obsidian, I can briefly disable the plugin, allow web connectivity, and replace the app. Sure, this would possibly look like paranoia to some, but it surely offers me the mandatory peace of thoughts that my information is protected.
