# What’s the difference: Dark Web, Deep Web & Grey Web?

## Key Facts

- The **Dark Web** requires specialized software like Tor, the Deep Web contains everyday
  protected content like email and banking, and the Grey Web is legally ambiguous.
- The **Deep Web** comprises approximately 90-95% of the entire internet. The surface web
  represents just 5-10% of all online content.
- **Onion routing** was developed by the U.S. Naval Research Laboratory in the mid-1990s
  for secure military communication, becoming publicly available as Tor in 2002.
- The **Grey Web** is accessible via standard browsers but its content drifts between
  legal and ethical acceptability by jurisdiction. Examples include torrent sites and
  cryptocurrency mixers.

## 1. Introduction: Dark Web, Deep Web & Grey Web

Black markets for drugs, cybercrime and hacking, as well as terrorism and dangerous
content are topics that first come to mind when talking about the Dark Web. The media
often portrays the Dark Web as a purely dangerous underworld full of criminals, hackers,
and illegal activities. Leaked data, stolen identities, and compromised credentials
routinely end up on Dark Web [marketplaces](https://www.corbado.com/passkeys-for-e-commerce), often without the
knowledge of victims. While some truth underlies these dramatic portrayals, this
perspective is often incomplete and oversimplified even though some of the greatest
threats to your personal information are lurking in this digital space called the Dark
Web.

In this blog we are aim to move past sensational headlines about the Dark Web and explain
what it is really all about, while also providing actionable insight for your cyber
security. In the process, we will be answering a few leading questions about the topic:

- What is the difference between Dark Web, Deep Web and Grey Web?

- How to use tools associated with the Dark Web and how to stay safe?

- What legitimate uses of the Dark Web are there and how can they benefit you?

## 2. What is the Dark Web?

When people hear “Dark Web,” they often think of a mysterious and shadowy place hidden
deep within the internet. In reality, the Dark Web is simply a part of the internet
intentionally concealed from standard search engines (Google, Bing, Yahoo, Yandex etc.).
It can’t be accessed with a regular browser like Chrome, Firefox, or Safari.

Instead, specialized browsers or software, like
[Tor (The Onion Router)](https://www.torproject.org/), are needed to access its hidden
content. This structure ensures the anonymity of users and website operators, protecting
their identities and locations from being tracked.

### 2.1 Historical Context of the Dark Web

The concept behind the Dark Web has surprisingly legitimate origins, rooted in privacy and
secure communication:

- **Mid-1990s:** Researchers at the U.S. Naval Research Laboratory developed the
  foundational technology known as _“onion routing”._ The primary objective was ensuring
  secure, anonymous communication channels for intelligence and military operations.

- **2002:** Recognizing the broader potential for enhancing online privacy for everyone,
  the onion routing technology evolved into what we now know as the Tor network, becoming
  publicly available and free for widespread use.

- **2002–present:** Tor and consequently, the Dark Web, became accessible to any internet
  user seeking online anonymity, whether for ethical activities like journalism and
  activism, or for illicit and unethical purposes.

### 2.2 Technical Overview

Understanding the Dark Web requires knowing a bit about how it operates behind the scenes.
Its cornerstone is a technology known as
“[onion routing](https://www.geeksforgeeks.org/computer-networks/onion-routing/),” which
layers encryption around a user’s communication like the layers of an onion. When someone
accesses a website through the Dark Web, their connection is passed through multiple
nodes, or servers, each stripping away one layer of encryption. No single node sees the
entire picture. This process makes it exceptionally difficult to trace users, offering
strong anonymity. To handle such complex and secure connections smoothly, using
[fully managed VPS hosting](https://ultahost.com/vps-hosting) ensures the right balance of
control and support without the hassle of managing everything yourself.

### 2.3 What you might find on the Dark Web

Contrary to popular imagination, the Dark Web is not solely a place of illicit activity.
It hosts a wide range of content:

#### 2.3.1 Legal and Ethical Uses

- **Whistleblower platforms and leak sites:** Used by journalists, activists, and
  whistleblowers (e.g., SecureDrop, WikiLeaks mirror sites).

- **Censorship-resistant communication:** Forums, messaging channels, and news platforms
  used by people living under oppressive regimes to safely discuss politics and share
  information.

- **Privacy-focused communities:** Forums dedicated to privacy tools, digital rights
  advocacy, cryptography, or cybersecurity topics.

- **Libraries and repositories:** Collections of free, uncensored information, educational
  resources, and documents (e.g., academic papers, technical guides, books).

- **Cryptocurrency-related forums and marketplaces:** Discussions about digital currencies
  and trading platforms with enhanced privacy features.

#### 2.3.2 Illegal Activities

- **Black-market marketplaces:** Sale of drugs, weapons, fake documents (e.g., passports,
  IDs), counterfeit products, and hacking services.

- **Stolen data exchanges:** [Marketplaces](https://www.corbado.com/passkeys-for-e-commerce) selling leaked
  databases, hacked accounts, credit cards, or personal identity information.

- **Malware and cybercrime tools:** Distribution of [ransomware](https://www.corbado.com/glossary/ransomware),
  [exploit](https://www.corbado.com/glossary/exploit) kits, hacking guides, [botnets](https://www.corbado.com/glossary/botnet), and
  other malicious software.

- **Illegal pornography and exploitative material:** Hosting or trading of content
  prohibited by law (e.g., explicit illegal materials).

- **Fraud-related communities:** Forums discussing identity theft methods, financial fraud
  techniques, and guides on illegal money-making schemes.

- **Darknet hacking forums:** Communities sharing hacking techniques, zero-day
  [exploits](https://www.corbado.com/glossary/exploit), and coordinating cyber-attacks.

### 2.4 Rules to stay safe on the Dark Web

Going onto the Dark Web can carry significant risks if you’re unaware or unprepared. Given
its anonymous nature, the Dark Web is home to scams, malicious content, and various other
threats that can compromise your security or identity. If you choose to explore it,
following these critical safety guidelines can significantly reduce your risks:

1. **Always use a secure and updated browser**: Utilize trusted dark-web-specific
   browsers, like Tor, and ensure they’re always up-to-date to protect against known
   [vulnerabilities](https://www.corbado.com/glossary/vulnerability).

2. **Avoid sharing personal information**: Never disclose your real name, address, or any
   personal details, even in seemingly trustworthy forums or chat rooms.

3. **Never download or open files from untrusted sources**: Files downloaded from the Dark
   Web can be malicious, infected with [malware](https://www.corbado.com/glossary/malware),
   [ransomware](https://www.corbado.com/glossary/ransomware), or spyware.

4. **Use a reputable VPN (Virtual Private Network)**: Even though the Tor network
   anonymizes your connection, using a VPN such as
   [VeePN](https://veepn.com/vpn-apps/vpn-for-mac/) provides an additional layer of
   security by masking your original IP address and encrypting your data.

5. **Stay alert and skeptical**: If an offer or deal seems too good to be true, it usually
   is. Trust no one easily because scams and [phishing](https://www.corbado.com/glossary/phishing) attacks are
   rampant on the Dark Web.

6. **Use disposable accounts and encrypted communication**: When communicating or creating
   accounts on the Dark Web, choose disposable email services and encrypted messaging
   platforms. Never reuse usernames or passwords from your regular online accounts. To
   further safeguard your personal information, consider employing
   [dark web monitoring](https://nordprotect.com/features/seamless-dark-web-monitoring/)
   services, which actively scan the Dark Web for your data and alert you to any potential
   breaches or misuse.

### 2.5 Dark Web Browsers and Tools you should know

Accessing the Dark Web safely requires specialized browsers and specific tools designed to
maintain privacy and anonymity. Here’s an overview of the most important browsers and
tools to be aware of if you plan to explore this hidden part of the internet:

- **Tor Browser**: The most widely used and recommended browser for accessing the Dark
  Web. Built upon Firefox, Tor uses onion routing technology to anonymize your connection,
  making tracking extremely difficult.

- **VPN (Virtual Private Network)**: While Tor anonymizes your identity, a reliable VPN
  encrypts your traffic and adds an extra layer of privacy and security.

- **PGP Encryption (Pretty Good Privacy)**: A powerful encryption standard that allows you
  to securely communicate or share files by encrypting emails or documents so only the
  intended recipient can access them.

- **Secure and Disposable Email Services**: Services like ProtonMail or temporary
  disposable emails (Guerrilla Mail, Temp Mail) provide an extra layer of anonymity when
  interacting on Dark Web sites or forums.

- **Cryptocurrency Wallets**: Cryptocurrencies such as Bitcoin are common
  [payment](https://www.corbado.com/passkeys-for-payment) methods on the Dark Web due to their
  anonymity-enhancing features. Familiarity with secure crypto
  [wallets](https://www.corbado.com/blog/digital-wallet-assurance) (such as hardware
  [wallets](https://www.corbado.com/blog/digital-wallet-assurance) or trusted online
  [wallets](https://www.corbado.com/blog/digital-wallet-assurance)) is essential if conducting transactions.

## 3. What is the Dark Net?

The **Dark Net** is a decentralized and private segment of the internet infrastructure
designed for enhanced privacy and anonymity. Unlike the publicly accessible internet,
which operates on centralized servers and openly accessible protocols, the dark net is
built upon specialized networks that require specific software, configurations, or
peer-to-peer protocols. This unique setup ensures user anonymity, strong encryption, and
resistance to external monitoring or censorship.

### 3.1 How the Dark Net differs from the Dark Web

Though often confused, the terms “Dark Web” and “Dark Net” refer to different concepts:

- **Dark Web**: Refers specifically to websites and content accessed through specialized
  browsers (like Tor). It’s essentially the content itself.

- **Dark Net**: Refers to the underlying private network infrastructure that hosts Dark
  Web websites, providing the technical foundation and anonymity features.

In short, the Dark Web is the content, while the Dark Net is the secure network
infrastructure on which this content resides.

### 3.2 Examples of Dark Net Networks

Several notable dark net platforms and technologies exist today, each with unique features
and goals:

- **I2P (Invisible Internet Project)**: Another decentralized and anonymous network that
  enables secure and private communication, including websites, messaging, file sharing,
  and more, operating entirely separate from the conventional internet.

- **Freenet**: A decentralized, censorship-resistant peer-to-peer network designed to
  facilitate free speech and information sharing anonymously.

- **ZeroNet**: A decentralized web platform built on blockchain and peer-to-peer
  technologies, where websites are hosted and shared directly among users without central
  servers

## 4. What is the Deep Web?

The Deep Web is simply the portion of the internet that isn’t indexed by regular search
engines like Google, Bing, or Yahoo. This means the pages and content in this part of the
web aren’t easily discoverable through a typical web search.

Unlike the Surface Web, which is the publicly accessible internet you browse every day,
the deep web contains content intentionally or naturally hidden from standard search
engines. This hidden content makes up the vast majority of online information, dwarfing
the publicly indexed pages available through typical searches. That is because of password
protection and user authentication, content behind paywalls, dynamic or personalized
content:

- Email inboxes and private messages

- Online [banking](https://www.corbado.com/passkeys-for-banking) and [financial services](https://www.corbado.com/passkeys-for-banking)

- Social media profiles set to private

- Subscription platforms and streaming services

- Academic journals and scientific databases

The deep web is hidden but still immense. While exact measurements vary, estimates
consistently suggest that it comprises approximately 90–95% of the entire internet. The
publicly accessible surface web, by comparison, represents just a small fraction, roughly
5–10% of all available online content.

## 5. What is the Grey Web?

While many internet users have heard of the Surface Web and the Dark Web, fewer people
know about the Grey Web. This lesser-known segment of the internet sits in a middle
ground, neither fully public nor fully hidden. Unlike the clearly defined boundaries of
the Dark Web (which requires specialized browsers and is intentionally anonymous) and the
open accessibility of the Surface Web, the Grey Web occupies an uncertain space
characterized by ambiguity around the legality, ethics, or legitimacy of its content.

The Grey Web isn’t inherently illegal or malicious, but its content often operates on the
fringes of accepted norms or regulations. Websites and platforms on the grey web might be
accessible via standard browsers, yet they frequently drift in and out of legal and
ethical acceptability based on varying regulations and jurisdictions.

Some typical examples of the grey web include:

- Streaming sites

- Unregulated [marketplaces](https://www.corbado.com/passkeys-for-e-commerce)

- Controversial forums and blogs

- Online Gambling Websites

- Torrent Websites

- Cryptocurrency Mixers

- Hacking or Security Forums

- Data Brokers and People-Search Services

## 6. How Corbado can help

One line in section 2.3.2 is the part of this article that touches most companies:
marketplaces selling leaked databases and hacked accounts. Those listings have a shelf
life, because a stolen password is only worth buying while it still opens a login. That
gives a company a fairly narrow question to answer about itself: how much of our login
volume still runs on a secret that someone could resell, and how quickly is that share
shrinking. [Corbado Observe](https://www.corbado.com/observe), the
[authentication observability](https://www.corbado.com/blog/authentication-observability) layer, answers both.

- **The resellable share.** Every login is classified into subflows, so password logins,
  one-time codes and passkey logins are counted separately. The first two are the part of
  your traffic that a credential dump can still be used against.
- **A date instead of a direction.** Adoption Forecast runs a Monte Carlo projection
  grounded in your measured OS mix and the share of each OS that reports a platform
  [authenticator](https://www.corbado.com/glossary/authenticator), with the enrollment strategy and the login
  frequency as parameters you set. "We are moving to passkeys" turns into a projected
  passkey rate with a timeline attached, and you can see which assumption carries it.
- **The cohorts that stay behind.** The Technology view segments by operating system, OS
  version and browser, and [Client Capabilities](https://www.corbado.com/blog/webauthn-client-capabilities)
  charts the share of sessions reporting a user-verifying
  [platform authenticator](https://www.corbado.com/glossary/platform-authenticator), which is where the residual
  password population is named instead of estimated. Both read your web traffic, so a base
  that logs in mainly through a mobile app will look smaller here than it is.
- **The other door.** Account recovery is tracked as a flow type in its own right, with
  its own funnel next to login, signup and enrollment. An email link or one-time code path
  that hands out access to whoever controls the inbox is measured rather than forgotten
  behind the login.

[Video: Adoption forecast](https://www.corbado.com/videos/features/adoption-forecast.mp4) ([See Adoption Forecast in Corbado Observe](https://www.corbado.com/observe/adoption-forecast))

Shrinking that share is [Corbado Connect](https://www.corbado.com/connect): passkeys in front of an identity
provider you already run, with gated prompts and
[Passkey Intelligence](https://docs.corbado.com/corbado-connect/features/passkey-intelligence)
to reach up to 10x higher [passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case). A
passkey private key never leaves the device it was created on, so there is nothing about
it for a [marketplace](https://www.corbado.com/passkeys-for-e-commerce) to list.
