What Is the Deep Web?

The deep web refers to parts of the internet that search engines cannot fully access. It consists of unindexed pages, such as private databases, confidential information, paywall sites, and restricted content requiring login credentials. The deep web is often accessed for harmless activities, providing valuable privacy by ensuring that information is only accessible to authorized individuals.

The Deep Web and Cybersecurity

While predominantly harmless, the deep web can raise cybersecurity concerns when individuals exploit its privacy for illicit purposes or engage in cyber threat activities. Threat actors target the deep web to breach private information, and risks can arise if internet safety is not practiced. Navigating various pathways within the deep web can also lead users to disturbing or harmful pages, such as piracy sites, political extremist forums, or violent content. 

The dark web is also a well-known section of the deep web that poses significant risks to cybersecurity. It’s essential to understand the purposes of the deep web to safeguard organizational assets and mitigate potential risks. Implementing safety measures such as security monitoring services, multi-factor authentication, security training, and endpoint security can help identify and prevent cyber threats.

Purposes of the Deep Web

The deep web is a secure platform allowing users to store and access information while maintaining privacy. Its purpose is to provide advantages to users who wish to preserve information without making it publicly accessible to everyone. Organizations can safeguard their data and control who has access to it, restricting unnecessary visibility. Content found on the deep web includes:

Private databases
Confidential information 
Internal company networks
Government documents

Deep Web vs. Surface Web

The surface web represents the visible portion of the internet accessible to anyone. Websites on the surface web are indexed by search engines, making them easily discoverable through standard search queries. The deep web exists as a layer beneath the surface web—while it is generally accessible, its contents are not indexed by search engines or found on search engine result pages.

Deep Web vs. Dark Web

While the deep web is part of the internet that is not readily visible to users, the dark web is a small section within the deep web that can only be accessed through specific browsers, like Tor. Websites on the dark web are intentionally hidden, requiring users to know the exact URL of sites to navigate the dark web. Although the dark web provides an additional layer of privacy for anonymous browsing and activities, it also carries substantial cyber risks due to its secretive nature. Illegal activities and illicit transactions are prevalent within the dark web, making it a hub for criminal behavior.
