The main difference between the Dark Web and the Deep Web lies in accessibility and content.

The Deep Web refers to parts of the internet that are not indexed by search engines but can still be accessed with the correct URL, login credentials, or payment. Examples of Deep Web content include online banking portals, academic journals, and subscription services.

In contrast, the Dark Web requires specialized software like Tor to access and focuses on maintaining user anonymity. Unlike the Deep Web, the Dark Web is home to both legal and illegal activities, as it provides users with complete privacy and untraceable browsing.

The web is much more than meets the eye, tons of it is hidden in the Deep and Dark Web levels.

What is the Deep Web?

The Deep Web refers to the part of the internet that is not indexed by standard search engines. Unlike the public-facing websites you encounter daily, the Deep Web includes content hidden behind login pages, paywalls, or private networks; and is largely owned by large corporates, service providers, or governments.

Examples of Deep Web content include:

  • Password-protected platforms (e.g., email accounts, online banking).
  • Private databases (e.g., academic journals, medical records).
  • Dynamic web pages (e.g., search results that aren’t static URLs).

The size of the Deep Web is estimated to be 1,000 times larger than the surface web (the “normal” Internet that can be easily accessed through search engines like Google).

Potential Applications for the Deep Web

There is a long list of potential applications for the Deep Web.

  • Online Banking: Many banks use the Deep Web to securely communicate with customers and manage financial transactions.
  • Government Communications: Government agencies use the Deep Web to communicate securely and share sensitive information.
  • Academic Databases: Universities and other education institutions use the Deep Web to access databases and archives containing research papers, journals, and other scholarly materials.
  • E-commerce: Online retailers use the Deep Web to manage orders, shipping, and inventory data.
  • Cloud Storage: Cloud storage services use the Deep Web to securely store and access data.
  • Healthcare: The healthcare industry uses the Deep Web to securely store and access patient records and medical information.
  • Scientific Research: Scientists and researchers use the Deep Web to access databases and simulations for their work.
  • Law Enforcement: Law enforcement agencies use the Deep Web to access criminal databases and share information.
  • Job Searching: Many job search websites use the Deep Web to store applicants’ resumes and employers’ job postings.
  • Market Research: Market researchers use the Deep Web to access data on consumer behavior and market trends.

What is the Dark Web?

The Dark Web refers to the part of the Internet that is intentionally hidden from regular search engines and can only be accessed through specific software, such as the Tor browser.

Websites on the Dark Web often run on networks of private servers that allow communication only via specific means. This enables a high degree of anonymity and makes it difficult for authorities to shut down.

Tor Network and Onion Routing are often mentioned when people talk about the Dark Web – mainly because the Dark Websites can only be accessed through the Tor network.

While there are different top-level domains – such as .bit and .i2p, that were specially made for Dark Web websites; most sites on the Dark Web are on “.onion” extension.

For example, this is the .onion address for Ahmia.fi, a popular search engine on the Dark Web.

Potential Applications for the Dark Web

While (unfortunately) the nature of anonymity makes the Dark Web a hotbed for many illegal or immoral activities, there are other possible uses for the technology:

  • Whistleblowing: Whistleblowers can use the Dark Web to share sensitive information without revealing their identity. For example, Edward Snowden resorted to the Dark Web when he leaked many of the revelations that helped to unmask NSA surveillance.
  • Political Activism: Political activists can use the Dark Web to organize and communicate with one another without fear of government retaliation.
  • Research & Journalism: Journalists and researchers can use the Dark Web to access information and sources that may not be available through traditional channels. Dark Web tools like Secure Drop is widely used by journalists and news organizations to receive information securely from their sources.
  • Online Privacy: People concerned about online privacy can use the Dark Web to protect their personal information and online activity from being tracked or monitored.

To Recap

The Deep Web is the part of the Internet that is often password-protected AND isn’t indexed by search engines like Google and Bing.

The Dark Web, on the other hand, is a hidden space of the internet that can only be accessed through special browser like the Tor. It is well-known for its association with illegal and immoral activities, as well as legitimate uses like political activism and journalism.
