A good part of the Internet is invisible to regular browsers and known as the deep web; a component of the deep web is the dark web, content which relies on the internet but isn’t available to regular browsers. While the dark web is used for legitimate purposes by businesses and other private networks, it is also commonly associated with the less salubrious aspects of the internet including criminal activity. Accessing the dark web is generally accomplished with specific software and configurations including ‘onion’ browsers the best known of which is probably Tor (The Onion Router).
