These three terms are often a source of confusion, especially in connection with cybercrime and where that comes from.

If you think that search engines like Google (there are more!) know about everything on the internet, you'd be wrong. Some stats from show at the start of November 2017, search engines have indexed at around 4.57 billion pages.

The section of the internet that is being indexed by search engines is known as the “Surface Web” or “Visible Web”. Now, 4.5 billion pages is a lot, but you'd be surprised to know that in reality it's only 10 percent of the whole web. It's the "surf" of the ocean of the whole internet. The reason search engines can see the surface web is through their web crawlers that read the website data, index it, and follow the links. So, what is the 90% that lies under the surface?

How is the Dark Web different from the Deep Web?

At the moment, the Dark Web is defined as a layer of information and pages that you can only get access to through so-called "overlay networks", which run on top of the normal internet and obscure access. You need special software to access the Dark Web because a lot of it is encrypted, and most of the dark web pages are hosted anonymously.

There are several tools used for reaching these parts of the internet. The TOR (The Onion Router) maintains the most popular tool for Dark Web access. Their primary product is the Tor browser. If you think you are completely anonymous though, think again. Law enforcement routinely shuts down and prosecutes sites and people doing illegal things on the Dark Web.

Digital credentials such as usernames and passwords connect you and your employees to critical business applications, as well as online services. Unfortunately, criminals know this and that's why digital credentials are among the most valuable assets found on the Dark Web. Learn more:
