When our every action online is tracked, privacy protection solutions become not a luxury but a necessity. One of the most powerful yet controversial tools is Tor Browser. Some use it for anonymity and freedom of expression, while others dive into the depths of the dark web. In this article, we will debunk the myths and tell the truth about Tor Browser: what it’s for, how it works, and what people say about it in different countries.

What Is Tor Browser

Tor (The Onion Router) is a free, open-source web browser created to ensure online anonymity. It is based on routing traffic through several encrypted nodes, known as "onion" nodes (due to their layered protection structure). This approach hides your IP address and makes it nearly impossible to track your online activity.

Tor is especially popular among those who care about privacy: journalists, human rights and political activists, and users from countries with Internet censorship. Unlike regular browsers, Tor blocks scripts, tracking, and browser fingerprinting by default, providing a higher level of privacy.

How Tor Browser Works

Tor works on the principle of "onion routing": your traffic passes through at least three random servers, called nodes. It’s roughly an Internet route with three transfers:
  1. The entry node knows your IP address but doesn’t know which site you’re going to.
  2. The middle node forwards traffic without knowing either the sender or the recipient.
  3. The exit node decrypts the last layer of data and sends it to the site but doesn’t know who originally made the request.
The data is encrypted several times, and then each encryption layer is successively removed, like the layers of an onion — hence the name of the technology. Even if someone intercepts the traffic, they will only see its fragment, not the entire connection chain.

What Tor Browser Is Used For

Tor Browser is used for various purposes related to anonymity, security, and bypassing restrictions.

Privacy Protection
Ordinary users use Tor to hide their location and IP address, especially when accessing sensitive information, registering on forums, or exchanging personal data.

Bypassing Censorship
In countries with strict Internet controls, Tor helps bypass blocks and access prohibited sites, such as social media platforms, news resources, or YouTube.

Journalists and Activists
Media representatives and human rights organizations use Tor to securely transmit information and communicate with informants without the risk of being tracked.

Accessing the Darknet
Tor provides access to sites in the .onion domain that are not accessible through regular browsers. These can range from harmless alternative hosting platforms (e.g., a copy of Wikipedia) to black markets, hence Tor’s reputation as a tool for accessing the "dark side of the Internet."

Developers and Researchers
Security engineers and scientists use Tor to test configurations, analyze network behavior, or experiment with tracking protection.

Advantages of Tor Browser

Using Tor Browser brings you the following advantages:

Anonymity
Tor effectively hides your IP address, making it nearly impossible to track your online activities. Neither your Internet provider nor the websites you visit can easily determine who you are or where you’re from.

Bypassing Blocks
Tor allows you to bypass restrictions and access websites and services banned in a particular country or region.

Safety in Public Networks
Tor Browser reduces the risk of data interception on public Wi-Fi networks. While it’s not a complete encryption solution, it complicates traffic analysis.

Free and Open Source
Tor is an open-source project developed and distributed for free. Its code is public and available for review, which builds trust among security professionals.

Disadvantages of Tor Browser

Tor Browser also comes with its disadvantages:

Low Speed
Since Tor encrypts data and routes it through multiple nodes, your Internet traffic slows down significantly. This can be inconvenient when watching videos, downloading large files, or using resource-heavy services.

Exit Node Vulnerability
The last (exit) node in the chain sees unencrypted traffic if you’re not using HTTPS. This means your data can be intercepted if you don’t ensure additional encryption.

Risks if Used Incorrectly
If a user reveals personal information through Tor (for example, logging into regular accounts), their anonymity may get compromised.

Website Blocks
Some websites block or restrict access from IP addresses known as Tor exit nodes to prevent abuse.

Is Tor Browser Safe

The question of Tor’s safety is complex and multi-faceted. Overall, Tor provides a high level of anonymity and protects against most forms of surveillance, but there are details to consider.

What Makes Tor Safe:
  • IP Address Masking: Your real IP address is hidden from visited websites and providers.
  • Traffic Encryption Inside the Tor Network: Data is encrypted between nodes.
  • Blocking Tracking Scripts: Tor Browser blocks most trackers and scripts that can reveal your activity by default.
  • Regular Updates: Developers constantly improve security and fix vulnerabilities.
Security Limitations:
  • Exit Node: As mentioned, your traffic is decrypted at the exit node. If you use unencrypted protocols (HTTP), your data can be intercepted.
  • Browser Vulnerabilities: Despite regular updates, like any software, Tor Browser can have bugs that attackers might exploit.
  • User Errors: Accidental data disclosure, installing malicious add-ons, or logging into personal accounts with real data reduces anonymity.
  • Traffic Correlation Attacks: If an attacker controls enough nodes or monitors both entry and exit points, they might attempt to correlate traffic and identify the user.

Tor is safe if used correctly and consciously. It does not guarantee complete protection but significantly increases online privacy compared to regular browsers.

Is it Legal to Use Tor Browser?

In most countries around the world, using Tor is not prohibited. It is a legal browser developed to protect privacy and online freedom. However, in some countries, the use of the browser is viewed with suspicion or is outright banned.
  • USA, European countries, Canada, Australia: The use of Tor is allowed and protected by law. Here, Tor is often used by journalists, human rights advocates, and ordinary users concerned about their privacy.
  • China: In China, access to the Tor network is blocked. Using Tor is considered a violation of Internet censorship and may lead to sanctions.
  • Iran: Similarly, the Iranian government blocks Tor, and attempts to bypass censorship are considered illegal.
  • Russia: In Russia, Tor is frequently blocked, and its use may attract the attention of law enforcement, especially if it is connected to accessing blocked websites.
  • Other countries with strict censorship: North Korea, Saudi Arabia, and some Middle Eastern countries also ban Tor or actively block its nodes.

Although Tor is a legal browser, its anonymity is sometimes abused for illegal purposes, such as trading prohibited goods or committing cybercrimes. However, the network and the browser themselves are not responsible for users' actions.


If you live in a country enforcing restrictions, you should study the local laws and assess the potential risks before using Tor.

How to Use Tor Browser

Step 1: Download Tor Browser

Go to the official Tor Project website and download the Tor Browser version for your operating system (Windows, macOS, Linux, Android).

Step 2: Install and Launch Tor Browser

Install Tor Browser like any other software following the instructions and launch it. When you first open it, Tor will automatically connect to the network.

Step 3: Connect to the Tor Network

You will see a window with a "Connect" button. If there are no access restrictions in your country, simply click it. If Tor is blocked in your country, use the bridge function: these are special nodes that help bypass blocks.

Step 4: Start Browsing

Once connected, you can use the browser like a regular one: enter website addresses, search for information. Tor automatically protects your anonymity and encrypts traffic.

Tips for Safe Tor Usage

  • Avoid logging into accounts that contain your real information if you want to stay anonymous.
  • Do not download or open suspicious files via Tor.
  • Use HTTPS websites to protect your data at the exit node.
  • Do not change the browser’s default security settings without fully understanding the consequences.
  • Do not install additional extensions or plugins—they can reveal your identity.

The Difference Between Tor, VPN, and Proxy

Although all three technologies — Tor, VPN, and proxies — serve to spoof your IP address and bypass restrictions, they work differently and offer varying levels of security and anonymity.

Tor

  • How it works: Multi-stage routing through several random nodes with multiple layers of encryption.
  • Advantages: High anonymity, difficult to track.
  • Disadvantages: Low speed, complex to use, exit nodes see unencrypted traffic.
  • Use: Ideal for those who prioritize privacy and are willing to sacrifice speed.

VPN (Virtual Private Network)

  • How it works: All your data is routed through a single intermediary server, which encrypts the traffic between you and the Internet.
  • Advantages: High speed, convenience, protection in public networks.
  • Disadvantages: Requires trusting the VPN provider, which can see your traffic.
  • Use: Suitable for bypassing blocks, protection against network surveillance, safe Internet access.

Proxies

  • How it works: The proxy server redirects your traffic, hiding your IP, but does not encrypt the data.
  • Advantages: Fast, easy to use.
  • Disadvantages: No encryption, low security.
  • Use: Often used to bypass blocks but not suitable for protecting privacy.

Alternatives to Tor Browser

While Tor is the most well-known solution for anonymous Internet access, there are other tools that offer privacy and security online. Here are the main ones:

1. I2P (Invisible Internet Project)

I2P is an anonymous network layered over the Internet, similar to Tor but using different protocols and architecture. It is more focused on hidden services and peer-to-peer applications, providing encryption and anonymity. I2P is often used for anonymous hosting and file sharing.

2. Freenet

Freenet is a decentralized platform for storing and sharing information, operating on the principle of distributed storage. It ensures user anonymity and protects content from censorship. It is suitable for publishing information that is difficult to remove.

3. VPN Services with Enhanced Anonymity

There are VPN providers specializing in maximum privacy (e.g., Mullvad, ProtonVPN). They not only encrypt traffic but also minimize user data collection, providing a high level of anonymity.

4. Brave Browser with Tor Functionality

Brave is a privacy-focused browser that allows opening tabs via the Tor network without the need to install Tor Browser separately. It’s a convenient option for those who want quick anonymity without having to switch browsers.
