VPN vs Proxy vs Tor: Learn the key differences in 2023

Introduction

Today, there are many ways to keep your personal information and safety safe when you use the internet. Multiple approaches and technologies exist for preserving your privacy and security online. People who want to stay anonymous and private online often use VPNs, web proxies, and Tor. It’s important to note that while all three of these technologies are useful, they all operate differently and provide varying degrees of security.

What is a proxy?

Proxy servers not only make networks safer, but they can also make web browsing more private. Clients can use it to connect to other servers in the network in a roundabout way. So, the client’s IP address is hidden, and the client can use resources on the server’s network that would be inaccessible otherwise. Proxy servers let people use the Internet without being tracked, filter web content and keep networks safe.

Different types of Proxy servers

There are several types of proxy servers, including:

Forward proxy: A forward proxy server acts as a gateway between a network and the internet, forwarding client requests to the internet and returning the response to the client.
Reverse proxy: A reverse proxy server sits in front of a group of web servers, forwarding client requests to the appropriate web server and returning the response to the client.
Transparent proxy: A transparent proxy server intercepts client requests and forwards them to the internet, but the client is unaware that it is communicating with a proxy server.
Anonymous proxy: An anonymous proxy server does not forward the client’s IP address to the internet, providing the client with anonymity.
Distorting proxy: A distorting proxy server forwards the client’s IP address to the internet but with a different IP address than the client’s actual IP address.
High anonymity proxy: A high anonymity proxy server does not forward the client’s IP address to the internet and also changes the client’s IP address, providing the client with a high level of anonymity.

How do proxy servers work?

A proxy server is a server that accepts network requests and either forwards them to the correct server or handles them itself. A proxy server acts as an intermediary between the client device (such as a computer or smartphone) and the target server. The proxy server evaluates the request and decides whether it can handle it internally or if it should be sent to another server.

Proxy server processes the request and returns the result to the client if it is successful. The proxy server will send the client’s request to the appropriate server and return the reply. This provides extra protection and anonymity for the proxy server’s client and server connections.

What is Tor?

When using Tor, you can surf the web anonymously because it is a free and open-source network of servers. Its goal is to keep people’s online activities private by routing them through a series of servers that will safely decrypt some data, and by those who value privacy when using the Internet. Businesses and other groups also use it to keep their private information and communications safe.

Tor security protocol

Tor is a free, open-source network protocol that gives internet users anonymity and privacy. It works by routing internet traffic through a network of volunteer-run servers, called “nodes” or relays,” “before it reaches its final destination.
The traffic is encrypted multiple times as it passes through the different nodes, with each layer of encryption being removed at the next node, hence the name “Onion Router.” This makes it hard for anyone watching network traffic to figure out where it came from or where it is going.
Users can use the Tor network to browse the internet anonymously, hide their location, and access websites that their government or ISP may block. It is also used for whistleblowing, political activism, and online markets for illegal goods that require a high level of privacy.

What is a VPN?

Virtual Private Network (VPN) software lets users connect to the internet safely by encrypting their traffic and sending it through a server. This makes a private, secure connection between the user’s device and the internet. This keeps other people from accessing the user’s data and personal information.

People and corporations use VPNs to protect their online activities and personal information. They can access stuff restricted in certain nations or areas.

How does a VPN service work?

When a user connects to a VPN, their internet traffic goes through the VPN server before it gets to its destination on the internet. This encrypts the traffic, protecting it from being accessed or tracked by third parties.

The VPN server acts as a go-between for the user’s device and the internet, hiding the user’s IP address and location. This lets the user see content that might not be available in their country or region. It also adds another layer of security and anonymity by making it hard for anyone to track the user’s internet activity or personal information.

The Benefits of Using a VPN

Enhanced privacy

An encrypted VPN masks your IP address. This makes it harder for other people to follow what you do online or figure out where you are.

Enhanced safety

A VPN can protect you from hacking, malware, and phishing attacks by encrypting your internet connection.

Bypassing web censorship

Traveling internationally can be difficult to gain access to information online due to geo-restrictions.

Accessing geographically restricted content

You can use a VPN to gain access to region-restricted content by connecting to a server in that region.

Unblocking streaming services

It’s common for streaming providers to restrict access to certain regions. VPNs allow you to connect to a server in a location where the service is available, allowing you to bypass geographic restrictions and gain access to the content.

Data protection

When you use public Wi-Fi, a VPN can help protect your data by encrypting your connection and stopping third parties from stealing your data.

Concerns regarding VPNs

While VPNs offer many benefits, there are also some concerns that users should be aware of:

Compatibility issues

Some VPNs may not work with all devices or operating systems or may have compatibility issues with specific applications or websites.

Trustworthiness of the VPN provider

It’s essential to choose a VPN service that has a good reputation and can be trusted because there have been cases of VPN services logging user data or selling it to third parties.

Legal things to think about

Depending on where you live, using a VPN may be against the law or limited by the government. It’s important to be aware of local laws and regulations before using a VPN.

Free VPNs: Should You Use Them?

Users who don’t want to pay for a VPN subscription but still want to protect their online privacy and access blocked content can use a free VPN. But there are a few things to consider before you use a free VPN since they may not offer the same level of security and privacy as paid VPNs.

Limited features

Free VPNs may have fewer features and less flexibility than paid VPNs. They may also have data caps or usage limits.

Slow speeds

Free VPNs may have slower connection speeds and lower bandwidth, which can affect the quality of your internet experience.

Security concerns

Some free VPNs have been known to collect and sell users’ data to third parties or to use weak encryption that can leave users vulnerable to cyber threats.

Generally, if you need a VPN for sensitive activities or want the best possible performance and support, it’s probably worth paying for a reputable VPN service. However, if you want to avoid geo-restrictions and occasional use, or if you have a low budget, free VPNs can be a good alternative.

Differences between Proxy and VPN

Proxy	VPN
A proxy server acts as a middleman between a client and the internet. It sends a client’s request to the internet and returns the response to the client.	A virtual private network (VPN) encrypts and tunnels all internet traffic through a remote server. This makes a secure and private connection between the client and the internet.
Provides anonymity by hiding the client’s IP address from the internet	Provides anonymity and privacy by encrypting all internet traffic and hiding the client’s IP address from the internet
Usually only works for web traffic (HTTP/HTTPS)	Encrypts all internet traffic, including web, email, and other protocols

Which is more efficient: VPN, proxy, or Tor?

The usefulness of virtual private networks (VPNs), web proxies (proxies), and the Tor anonymity network (Tor) is context dependent. So let’s say that protecting your anonymity and privacy when using the internet is your top priority. Tor, which uses a distributed network of encrypted servers, may be the best choice in such a scenario. Due to the additional layers of encryption, using Tor may not be the ideal option for high-bandwidth tasks like streaming or gaming, which rely on a fast internet connection.

Conclusions

Using a virtual private network (VPN), a proxy server, or Tor can help you remain anonymous and private when surfing the web. But their methods of operation and degrees of security are distinct. Choosing the proper technology requires thorough consideration of your individual requirements and objectives.
