Examples of web content: mailboxes, social networks, medical documentation, legal files, blog posts under moderation, a web page redesign that has not yet been published, etc.
The Deep web (“Invisible Network” or “Deep Web”) is located just below the surface web. Most of the deep web consists of regular sites that require users to create an account before an account becomes available. These are secure resources, such as Gmail or Netflix email, which gives you access to a paid subscription after filling out an online form and paying.
This is how the deep web works. Most of the Internet consists of databases and the Internet.
The latter includes files protected by privacy settings. They cannot be accessed without certain credentials (for example, login and password). Internal networks for government agencies, corporations or educational institutions are located on the Internet.
In simple words, all web pages that the search engine cannot track are considered part of the deep web. Content on the deep web is safer and cleaner than on the surface web, because it belongs to certain organizations that support and moderate it. In addition, the purity of the content helps to strengthen firewalls that control the access of various programs to the network.
But there are holes in the deep web. Some users manage to circumvent legal restrictions on access to content that is legally blocked in their geolocation. You can also illegally download movies, music, and other digital copyright products without paying for them.
And, of course, in this part of the deep web, you can run into malware or other cyber threat. Therefore, organizations try to protect their resources in the deep web as reliably as possible.
