Cloudflare's Browsing Experience Security Check online tool tests the capabilities of the web browser in regards to certain privacy and security related features.

For a subset of Internet users, privacy is of uttermost importance. While the majority seems indifferent, some try their best to implement protective mechanisms to eliminate or at least reduce what companies and maybe even State actors may find out about them when they use the Internet.

Whether that is successful or not depends on the program used to connect to Internet sites, e.g. a browser or media client, and also the system configuration.
