What is Deep Web?

The deep web is the portion of the World Wide Web (WWW) that is relatively hidden and much harder to access than the surface web. The deep web contains web pages that are not indexed by traditional web search engines like Google. The deep web is said to make up over 99% of the internet, and is comprised of web mail, social media accounts, online banking, and other websites that sometimes require a password to access. The deep web is also made up of private databases and statistics from global government agencies, Non-Governmental Organizations (NGOs), large enterprises, and other constituents.
