“A browser extension that blocks bad websites without compromising your privacy?”
What sounds like an attempt to square the circle, actually can be done. Almost all browser extensions that aim to block harmful websites send each visited website to cloud servers that match the exact URL/address with a large database of known bad sites. That comes with the advantage of being able to filter sites very thoroughly on the URL level (different from DNS- or host-based filtering such as available in Emsisoft’s Web Protection feature), but the big downside of that approach is that the creators of such extensions can basically see all the websites you’re visiting and track you throughout all your online activities.
Our development team proves that things can be done in a better, more privacy-conscious way. Emsisoft Browser Security is a brand new extension, currently available for Chrome, Firefox and Edge, that not only blocks access to websites that distribute malware, but also prevents phishing attacks that try to steal your passwords.
How it works:
Instead of sending each full website URL to a cloud server for matching, it only sends a calculated hash value of the domain name of each newly visited site to our servers once and then receives a list of matching patterns that are applied locally on your computer. Those patterns are then kept for successive visits of pages on the same host/domain, which not only speeds up the matching significantly, but also means that Emsisoft doesn’t know any of the details of your browsing activity.
Installation of Emsisoft Browser Security
Emsisoft Browser Security works independently of Emsisoft Anti-Malware and can be obtained free of charge from the extension stores:
Get Emsisoft Browser Security for Chrome
Get Emsisoft Browser Security for Firefox
Get Emsisoft Browser Security for Edge (Chromium)
Get Emsisoft Browser Security for Edge (Legacy)
Users of alternative browsers please refer to our extended Emsisoft Browser Security User Guide for further information.
Emsisoft Anti-Malware asks you to install the extension if it’s missing.
Note: If Emsisoft Browser Security is installed and active in the browser for the profile you are currently using, and you attempt to access a website or webpage that Emsisoft Browser Security thinks is bad, a notification webpage will appear and the connection will be blocked.
If both Emsisoft Browser Security and Emsisoft Anti-Malware’s Web Protection are present and enabled, Web Protection will block the connection attempt first, and show a slide-out notification on the screen. In this case, the web browser will show an error indicating the website could not be reached.
