Written: · 16 min
The deep web consists of internet content that search engines cannot index and makes up nearly 90% of all websites. It includes password-protected email, bank statements, health records, and paywalled services that require standard browsers and proper credentials. The dark web forms a small hidden part of the deep web; users reach it only with special software such as Tor, launched on September 20, 2002. Accessing the dark web itself is not illegal in the United Kingdom, though certain activities on it remain prosecutable. (1) (2) (3) (4)
What Is the Deep Web?
The deep web refers to parts of the internet that are not indexed by search engines. This non-indexed content includes a variety of data and services, such as password-protected websites, dynamic web pages, and no-follow links that prevent search engines from accessing them (2).
Estimates suggest that the deep web constitutes about 90-95% of the total internet, making it significantly larger than the surface web, which is the part most users encounter through standard searches (1). Everyday examples of deep web content include online banking portals, medical records, academic databases, and corporate intranets. Accessing these resources typically requires authentication, such as usernames and passwords, which adds a layer of security and privacy (1).
The deep web is often confused with the dark web, but they are not the same. The dark web is a small segment of the deep web that is intentionally hidden and can only be accessed using special software like the Tor Browser (3) (2). While the dark web is associated with anonymity and can facilitate both legitimate and illegal activities, most deep web content is perfectly legal and accessible to users with the right credentials (3).
Understanding the deep web is essential for navigating online privacy layers effectively. Many users interact with deep web services daily without realizing it, highlighting the importance of recognizing its existence and significance in the broader context of internet usage.
What Is the Dark Web?
The dark web is a small, intentionally hidden subset of the deep web. It consists of internet sites that are not indexed by standard search engines and can only be accessed using special software, primarily the Tor Browser. This software enables users to browse anonymously, routing their internet traffic through multiple relays to conceal their identity and location (3).
Accessing the dark web requires specific tools and knowledge. The Tor network, which popularized the dark web, was launched in 2002 and was initially developed by the U.S. government (4). It uses a technique called "onion routing," where data is encrypted in layers, similar to the layers of an onion, making it difficult to trace (3). This design aims to protect user privacy, allowing both legitimate activities and illegal transactions to occur within its confines (3).
Estimates suggest that the dark web comprises approximately 0.01% to 0.1% of the total internet (3). This is a small fraction compared to the entire deep web, which accounts for nearly 90% of all websites (1). Despite its limited size, the dark web can host a variety of content, including marketplaces for illegal goods, forums for privacy advocates, and resources for whistleblowers (3).
While accessing the dark web is not illegal in itself, engaging in certain activities, such as purchasing illegal substances or accessing prohibited materials, can lead to prosecution (3). Awareness of these risks is crucial for anyone considering exploring this hidden part of the internet.

The Deep Web encompasses a vast portion of the internet, representing nearly 90% of all websites (1). It includes content that is not indexed, such as password-protected sites and private databases (2). Users typically access this content using standard web browsers, provided they have the necessary credentials (2) (1).
In contrast, the Dark Web is a smaller segment of the Deep Web, consisting of sites that are intentionally hidden and can only be accessed through networks like Tor (3). This portion is designed for anonymity, allowing users to engage in activities that may be legal or illegal (3). While accessing the Dark Web itself is not illegal in the United Kingdom, certain actions conducted on it can be prosecutable (3).
Understanding the differences between these two layers of the internet is essential for recognizing how online privacy works. The Deep Web serves primarily legitimate purposes, while the Dark Web is often associated with higher risks and anonymity challenges.
Common Misconceptions About the Deep Web and Dark Web
Several myths surround the Deep Web and Dark Web that can lead to misunderstanding their nature and purpose.
One common misconception is that the Deep Web is synonymous with illegal activities. In reality, the Deep Web consists of a vast range of content that is not indexed by search engines. This includes legitimate services such as online banking, medical records, and academic databases, which make up approximately 90% of all websites (1) (2). Accessing these services typically requires proper credentials, emphasizing their lawful nature.
Another myth is that the Deep Web and Dark Web are the same. The Dark Web is actually a small, intentionally hidden part of the Deep Web, accessible only through specialized software like the Tor Browser (3) (2). While the Dark Web can host illegal activities, it also serves legitimate purposes, such as facilitating privacy for activists and journalists (3).
It is also incorrect to assume that all users of the Dark Web are criminals. Many individuals use it to protect their privacy from surveillance or censorship. The Tor network, which popularized the Dark Web, was originally developed to safeguard the communications of U.S. intelligence personnel (4).
Additionally, not all content on the Dark Web requires Tor for access. Although many .onion sites utilize Tor for anonymity, some Dark Web content may be reachable through other means. However, using Tor is the most common method to ensure privacy while browsing this segment of the internet (3).
Understanding these misconceptions can help users navigate the complexities of online privacy. Awareness of the distinctions between the Deep Web and Dark Web is essential for recognizing the legitimate use cases alongside the associated risks.
Safety and Risks of the Deep Web
The Deep Web offers legitimate privacy benefits but also presents risks, particularly regarding data exposure.

Tools for Accessing the Deep and Dark Web
Several legitimate tools enable access to the Deep Web and Dark Web. Each has specific use cases and requirements.
Tor Browser
The Tor Browser is the most widely used tool for accessing the Dark Web. It uses onion routing to anonymize user traffic by routing it through multiple nodes. This design makes it difficult for anyone to trace users back to their original IP address (3). Tor is appropriate when privacy is a priority, such as for journalists or activists in oppressive regimes. To set it up, download the official Tor Browser from the Tor Project's website. Follow the installation prompts, and ensure that you do not alter the default security settings for maximum anonymity (4).
I2P
I2P (Invisible Internet Project) is another network designed for anonymous communication. It allows users to access both hidden services and standard sites while protecting their identity. I2P is suitable for peer-to-peer file sharing and anonymous browsing. It operates differently from Tor, using a decentralized structure. Users can download I2P from its official site and follow the installation guide, which includes configuring browser settings to access I2P sites (3).
Freenet
Freenet is a decentralized platform for censorship-resistant communication and publishing. It allows users to share files and publish websites anonymously. This tool is appropriate for those who want to share information without fear of censorship. To use Freenet, download it from the official website and follow the instructions for installation. Users should be aware that Freenet may require more technical knowledge for optimal setup and operation (3).
Official Warnings and Best Practices
When using these tools, it is crucial to follow official guidelines. Always download software from official sources to avoid malicious versions. Using a Virtual Private Network (VPN) in conjunction with these tools can enhance anonymity. Additionally, be cautious about sharing personal information and engaging in transactions, as these actions can compromise privacy and security (3). Avoid illegal activities, as engaging in them can lead to prosecution, regardless of the anonymity these tools provide (3).
Is It Legal to Access the Deep Web or Dark Web?
The legality of accessing the Deep Web and Dark Web varies by jurisdiction and is influenced by intent and activity. In general, simply accessing these areas of the internet is not illegal. The Deep Web consists of content that search engines cannot index, including data like online banking and medical records (2) (1). Most of this content is legal and used for legitimate purposes.
In the United States, no federal laws prohibit downloading the Tor browser or accessing .onion sites. However, engaging in illegal activities—such as purchasing drugs or child exploitation material—is prosecutable (3). The same applies to the European Union, where accessing the Dark Web is legal, but illegal activities are subject to law enforcement scrutiny.
Internationally, the perspective is similar. Most countries do not criminalize the act of accessing the Deep Web or Dark Web. Instead, the focus is on the legality of the activities conducted within these spaces. For example, using the Dark Web for whistleblowing or to bypass censorship can be seen as legal and justified in many regions.
Clarifying common queries, the Deep Web itself is not illegal. It includes a vast array of content that serves valid purposes, such as academic databases and private online services (2). However, the Dark Web, while a small segment of the Deep Web, often attracts attention due to its association with illegal marketplaces and activities (3). It is crucial to differentiate between accessing these layers of the internet and the actions taken within them.
To stay on the right side of the law, users should refrain from participating in illegal transactions or activities while accessing the Dark Web. Engaging in such actions can lead to serious legal consequences, regardless of the anonymity provided by tools like Tor. Understanding the legal landscape is essential for navigating both the Deep Web and Dark Web safely and responsibly.
Practical Checklist: How to Browse More Safely
To enhance safety while browsing the Deep and Dark Web, consider the following checklist. Implementing these measures can significantly reduce risks associated with online privacy.
Use a VPN with Tor
Combining a Virtual Private Network (VPN) with the Tor Browser adds an extra layer of anonymity. A VPN encrypts your internet connection, making it harder for third parties to monitor your activities. Choose a reputable VPN service that does not keep logs of user activities. This setup is particularly effective when accessing .onion sites, as it masks your IP address from both Tor and external observers (5).
Operational Security Basics
Adhere to operational security (OpSec) practices. Avoid sharing personal information, such as your name or location, while browsing. Use pseudonyms and anonymous email addresses for any registrations. Regularly update your passwords and utilize unique passwords for different services. Implement two-factor authentication wherever possible to add an additional layer of security.
Red-Flag Indicators
Be vigilant for red-flag indicators while exploring the Dark Web. These may include:
Unrealistic Offers: If something seems too good to be true, it likely is. Avoid websites promising free or highly discounted goods.
Poor Website Design: Many legitimate sites invest in quality design. Be cautious of poorly designed pages, which may indicate scams.
Lack of Reviews: Reputable vendors typically have user reviews. If there are no reviews or only negative ones, reconsider engaging.
Recommended Verification Resources
Utilize verification resources to assess the legitimacy of sites and vendors. Websites like Reddit and specialized forums can provide user feedback about specific .onion sites and vendors. Always cross-check information before making decisions to avoid scams and illegal activities.

Common questions
- How is the dark web?
The dark web forms a small hidden part of the deep web. It requires tools like Tor to reach sites that standard browsers cannot access. Content there ranges from legal forums to illegal marketplaces. Access works if you use official software but carries risks when users engage with untrusted sources.
- Is Tor 100% untraceable?
Tor prevents its own developers from tracing users through its design. This holds true if you follow official guidelines and avoid revealing personal details. It does not work when users install modified versions or share identifiable information. Law enforcement has traced some activities on Tor networks in the past.
- What is Tor?
Tor stands for The Onion Router. It routes traffic through multiple relays with layered encryption. The project launched on September 20 2002. You access it by downloading the official browser from the Tor Project site.
- Is DuckDuckGo dark web?
DuckDuckGo offers a version reachable via Tor. This version does not make the search engine part of the dark web itself. Standard DuckDuckGo operates on the surface web. The Tor version helps users reach .onion links without leaving the anonymized network.
- Deep web and dark web difference
The deep web includes all unindexed content such as email accounts and bank records. The dark web sits inside it as the intentionally concealed portion. Most deep web material needs only a login and standard browser. Dark web sites require special software like Tor and represent a small fraction of the total.
- Is the deep web illegal
The deep web itself is not illegal in the United Kingdom. It contains everyday services such as online banking statements and health records. Accessing it becomes illegal only when users perform prohibited actions. Manchester residents use deep web resources daily through password protected accounts without issue.
- Deep web examples
Deep web examples include electronic bank statements and private email inboxes. Corporate intranets and paywalled academic journals also belong to it. These require authentication yet use ordinary browsers. You check this yourself by logging into your UK bank account which sits outside search engine indexes.
Conclusions
Three key points stand out from the facts presented. First, the deep web covers most unindexed content and remains legal in the United Kingdom when used for everyday tasks such as checking bank statements in Manchester. Second, the dark web forms only a small hidden layer that requires Tor and carries higher risks if users visit untrusted sites or share personal data. Third, tools like Tor, I2P, and Freenet provide anonymity only when downloaded from official sources and combined with a no-logs VPN; this fails when users change default security settings or engage in illegal transactions.
