What is Tor?
Tor (short for “The onion router”) is a network used for anonymous communication. It has lots of servers scattered around the globe that are maintained by individual volunteers. This makes Tor connections difficult to intercept as they do not rely on a single company or organization. How does Tor work?
- When you enter a request, Tor software encrypts it three times for three different nodes – a guard node, a middle server and an exit node.
- The Tor software then sends it to the guard node. It removes one layer of encryption and passes it to the next server. The guard node can see your IP address, but it cannot read the encrypted message.
- The middle node peels the second layer off and passes the message and its final encryption layer to the exit node.
- The exit node removes the final layer and can see your decrypted message, but it cannot identify the sender. This node passes the message on to the recipient.
Is Tor safe?
The fourth step is the most sensitive one as the message could be visible to the person or organization operating the exit node. Anyone can set up a node, so its security depends on the owner. The only solution here is using an HTTPS connection, which is itself encrypted by transport layer security protocol (TLS), or an Onion Over VPN feature.
Is Tor safe? By operating both guard and exit nodes, someone could identify Tor users and their messages. An organization operating a large amount of Tor servers could intercept users, but it is unlikely that a single individual could do this. Organizations like the National Security Agency (NSA), however, could have the resources and desire to monitor the Tor network in this way.
- Its complex encryption process virtually guarantees full anonymity for Tor users.
- Free, easy-to-use software.
- Difficult to shut down or intercept as the traffic is spread among a large number of servers maintained by individual volunteers.
- Using different layers of encryption slows down your connection speed.
- Exit nodes may intercept message content.
- Poor accountability and transparency for the volunteers maintaining the nodes.
- To assume the IP address of a specific country, you will need to configure your connection or reconnect multiple times until you connect to a node in the country you need.
- Not available for all operating systems.

Is Tor a VPN?
No, it isn’t. Tor is a browser and only encrypts the data transmitting through the browser. A VPN is specific privacy protection software and encrypts all data coming out of a device, whether it comes from a browser or an app.
The key difference between a VPN and Tor are their operation methods. While a VPN encrypts and routes your traffic using a network of servers maintained by a centralized entity, Tor is a decentralized network operated by volunteers.
It is less user friendly, transparent, and much slower and more complex. However, it is still a powerful tool. If you need accountability, safety, and privacy, you should use a reliable VPN provider while using the Tor browser.
Is Tor illegal?
Using the Tor browser for anonymous communication and browsing online is legal in most countries and you don’t need to worry about getting in trouble. As long as you’re not involved in criminal activities, you can freely use the Tor browser.
Is Tor illegal anywhere? There are a handful of suppressive governments like China that restrict the use of the Tor browser and limit the freedom of speech. Using a VPN or Tor is often the only way for the locals to communicate with the outside world.
What is VPN software?
A VPN, or virtual private network, encrypts your data and sends it to an intermediary server. VPN service providers operate many servers in different locations and offer different VPN protocols and features, giving you plenty of choices. Comparatively, Tor encrypts your connection by routing through a randomized sequence of volunteer servers.
VPNs also encrypt your internet traffic, making it invisible to hackers and snoopers. Premium VPNs use top-grade 256-bit encryption systems, which are impossible to brute-force using any currently known and available device. With a VPN enabled on your gadget, you can hide your IP address and enhance your online privacy.
Protect your online identity with a VPN.
VPNs work like this:
- VPN software encrypts your internet traffic and sends it to a remote server that changes your IP address (check out our article on the IP location changer).
- A VPN server decrypts your data before delivering it to your end goal.
- Data arriving at your device from the network undergoes the same process.
As you can see, it requires way fewer steps than Tor to ensure security and privacy.
VPNs also encrypt your data, and hide your IP address. It’s easy to tell who runs the servers when it comes to reputable VPN providers, so the whole procedure is more transparent. There is always somebody accountable for the service, and they usually provide customer service. This makes it more stable and reliable than the Tor browser.
- Accountability because it’s easy to tell who owns the server.
- Easy to use, especially when provided by a VPN service.
- Provides online privacy as your data gets encrypted and you get a new IP address.
- Premium VPNs use advanced next-generation encryption.
- Faster than Tor due to a simpler routing scheme.
- You can easily choose the specialized server of your VPN provider or the country you need most.
- The system relies on a single provider and your information passes through fewer VPN servers, so it’s important to trust your provider.
- Premium VPNs are more expensive.
- Some VPNs collect user and connection logs (make sure your provider has a no-logs policy.
Differences between a VPN and Tor
Understanding the main differences between a VPN and Tor may help you choose the best option for your needs and preferences:
|Routes the traffic through a secure server owned by the provider.
|Routes traffic through multiple nodes (volunteer servers).
|Typically faster than Tor because it usually involves only one extra node.
|Generally slower due to the traffic passing through multiple nodes.
|Uses robust encryption protocols to secure all data between your device and the VPN server.
|Multi-layer encryption with each node only decrypting enough data to know where to send it next.
|Usually high. However, it depends on the VPN provider’s policies.
|Very high due to the traffic passing through several nodes, making it hard to trace the source.
|User friendly, typically offering simple apps for various devices.
|Requires downloading and using the Tor browser. May require technical know-how for further configuration.
|Ensures a secure and private connection when traveling.
|Ideal for tasks that require extra privacy. Not recommended for data-intensive tasks due to speed limitations.
|Trustworthy VPNs require a subscription.
|Free to use.
VPN and Tor: can they be used simultaneously?
You can use both Tor and VPN at the same time. The first method is accessing the Tor network by connecting to a VPN server beforehand. In this case, the Tor entry node operator will not see your IP and your ISP won’t know you’re using Tor. This also lets you bypass restrictions preventing you from accessing the Tor network. However, this method won’t protect you from malicious exit nodes as your traffic will be unencrypted when it reaches them.
If you go Tor > VPN, your traffic will be encrypted when it enters and exits the Tor network. You will need a special VPN provider that supports such a connection. While the VPN encryption protects you from malicious exit nodes, your ISP will be able to see that you are using Tor. However, you get less anonymity. Also be aware that both methods slow down your internet more than Tor already does.
If you wish to use the first method, check out NordVPN’s specialized and integrated Onion Over VPN feature.
Tor vs VPN: which is better?
Tor and VPN are two different tools serving different purposes. While there are multiple VPN providers, there is only one Tor network. When you connect to a VPN, your internet traffic is encapsulated in an encrypted tunnel, while Tor uses several layers of independent nodes.
Even though Tor and VPN applications overlap, there are more differences than similarities. VPN services provide you with transparent service and privacy protection, while Tor has less accountability and can be a potential target of security agencies.
We recommend using a VPN as it has way more features, more transparency, and high-end encryption mechanisms. Moreover, it won’t slow down your internet connection. VPN can protect your traffic in a more transparent way than Tor.
