The Deep Web is a term used to refer to parts of the Internet that are not accessible through traditional search engines. It is estimated that the Deep Web is 500 times larger than the surface web, with content that is not indexed by search engines such as Google or Bing. To access the Deep Web, you need to use specialized search tools such as Tor, I2P, Freenet, and others.

The Deep Web is composed of websites and databases that are not accessible to the general public, such as government and corporate intranets, library catalogs, and online forums. To access these sites, you need to use specialized tools that can tunnel through security walls and encryption.

The most popular tool used to access the Deep Web is the Tor browser. It is an open-source project that provides a secure and anonymous way to access the Deep Web. Tor routes your connection through multiple nodes, making it difficult to trace your activity. It also uses advanced encryption to protect your data from being intercepted.

In addition to Tor, there are other tools such as I2P, Freenet, and others that can be used to access the Deep Web. These tools provide different levels of anonymity and security, depending on your needs.

The Deep Web is an important resource for researchers, journalists, and other individuals who need access to information that is not available on the surface web. However, it is important to note that the Deep Web can also be used for illegal activities, so it is important to exercise caution when using it.
