3. Surface Web
• The websites we browse each day make up only a small percentage of
the internet.
• These sites, collectively known as the surface web, are visible and
accessible to common search engines such as Google and Yahoo.
While estimates vary, many experts agree that the surface web
comprises roughly 4% of all online content.
• Beyond the surface web, 96% of online content is found in the deep
web and the darknet.

5. Dark Net
• Beyond the deep web is the darknet. The darknet is a network, built
on top of the internet, that is purposefully hidden, meaning it has
been designed specifically for anonymity. Unlike the deep web, the
darknet is only accessible with special tools and software - browsers
and other protocol beyond direct links or credentials. You cannot
access the darknet by simply typing a dark web address into your web
browser.
