Billions of searches take place on the surface web every day. Synonymous with Google, this part of the web is indexed by search engines. Try searching your name and you’ll likely be met with thousands if not millions of results, a few of which are familiar to you – your social media profiles, bio on your employer’s website, mentions in the news. The surface, or “clear” web, is only the tip of the iceberg, as vast as it may seem. In fact, it makes up only 4% of the entire World Wide Web. A much larger chunk of the web, the deep web, lies beneath the surface and is not indexed by search engines – but it is still just as important for security professionals to monitor.
