It can be used to test proxy and SOCKS servers, view details about a VPN server, and check whether an IP address appears on blacklists. The tool also reports whether Flash and Java are enabled, and displays language preferences, system configuration, operating system, browser details, and DNS information.

Its core functionality is interactive analysis using Java, Flash, and WebRTC to reveal the computer’s actual system settings. This process can highlight potential weaknesses and data points that third-party sites might use to identify or gather information about a user’s device.
