Why does the Deep Web exist?

A simple answer to the above question is because we need to hide certain things. For instance, if you have an Internet Banking account, your account details are on the Internet. However, they cannot be accessed by a simple Google search. Thus, your account pages are secure and safe in the Deep Web. Without the Deep Web, it is safe to assume that the Internet would have been much less useful. We would not be able to have social networks, Internet Banking, E-shopping, etc. as these sites store your sensitive data on Deep Web to make them secure.

It also exists to store a large amount of data of the corporate world. For instance, many large corporations store their business-related data on Deep Web. This provides them with safety and security.

You might be surprised to know that you access Deep Web almost every day. Yes, as said earlier, your social networking accounts, your email, etc. store your personal data on Deep Web, hence whenever you access your email, your bank statement, Twitter DMs, your office intranet, etc. are all a part of Deep Web. However, all of the above things are not always secure, and you are not anonymous on the Surface Web, even if it is connected to Deep Web. This constant need for anonymity and privacy from the governmental surveillance led to the formation of Dark Web.
