VPNs and proxy servers offer various ways in which you can access the internet privately, protect your identity and bypass geo-restrictions. However, a VPN gives you more security and privacy than a proxy server. You can use a VPN or a proxy server, depending on your online tasks.
In this ultimate guide, you will learn the differences there’s to know about VPNs and proxy servers.
A VPN or Virtual Private Network secures your connection and hides your IP address over the internet. It does this by tunneling your internet traffic between your device and the internet. Besides tunneling, the VPN service also encrypts your internet traffic and routes it through a VPN server.
Encryption ensures that no one will know what your internet traffic entails. Hence your online activities are generally safe from sniffers, eavesdroppers, your ISP, and even the government. When your traffic is routed through the VPN server, the server assigns you a new IP address.
The server’s IP address masks your actual IP address. Online entities and services you access will only see the server’s IP address. This is how the VPN gives you online privacy. Paid VPN services implement other mechanisms and features to ensure that your data is safe, private, and secure.
It’s important to note a VPN provider will only enhance your online privacy if you aren’t simultaneously logged into an online account that knows about your identity, such as Facebook or Gmail. A VPN in itself does not guarantee online privacy.
A proxy server acts as an intermediary that ‘surfs the internet’ on your behalf. When you access the internet through the proxy server, the proxy handles all your needs. It receives your requests and sends them to websites and online services.
It then receives and forwards the results from the websites and online services to you. The internet services you access will only see the IP address of the proxy server. Hence, the proxy server masks your actual IP address.
Unlike VPNs, most proxy servers don’t encrypt your online traffic.
Let us look at some common types of proxy servers you can use as your daily drivers.
HTTP Proxy servers
These are the most popular proxy servers. They are used for website traffic and hence gaining access to geo-restricted websites.
SOCKS Proxy servers
These servers can handle any type of traffic besides web traffic. They are popularly used for online gaming, file sharing, and video streaming. However, they are usually slow and congested.
Transparent Proxy servers
These proxy servers are used to monitor the online activities of connected users. They are used for blocking access to websites, verifying Wi-Fi logins, and even for parental control. They are known as transparent because users don’t know of their existence.
Setting up a VPN involves installations and subscriptions. Here are quick steps on how to set up a VPN on any device.
Unlike VPNs, you don’t need to install proxy servers. You only configure them. Paid proxy servers will require a subscription. The proxy provider will give you a proxy IP address and port number or the proxy auto-config file (.pac file)/ proxy script address. However, some proxy server providers may require that you install an extension.
Here is how to configure proxy servers on various platforms.
This method eliminates the process of setting up the proxy on various applications.
Setting up the proxy using proxy auto-config file .pac:
Setting up the proxy using the IP address and port number:
To use the proxy on other browsers, use the above platform method.
Here is a brief overview:
|VPN (Virtual Private Network)||Proxy server|
|Encryption||Encrypts all your internet connection.||Doesn’t encrypt your internet connection.|
|Coverage||Works with all your internet traffic||Works with web and specific apps’ traffic.|
|Logging||No-log policy (premium VPNs).||Logs your activities.|
|Reliability||More reliable.||Less reliable.|
Let’s take an in-depth look.
VPNs secure your internet connection with impeccable encryption while Proxy servers don’t. The encryption ensures that no one will gain access to your online activities and sensitive data – provided you follow common safety practices. Hence, a VPN protects you from prying eyes such as hackers, your ISP, and even the government – again, provided you follow internet safety practices (such as not using Gmail, Facbeook, etc. together with your VPN).
VPNs tunnel your internet connection on the operating system level. Any incoming or outgoing connections must pass through the VPN. Some VPNs also allow you to set which apps or services can use the VPN tunnel. This is via split tunneling.
On the other hand, proxy servers work on the application level. They route web traffic or traffic from certain apps that allow proxy connections.
Some paid VPNs have a strict no-log policy. They do not store or log any activities you undertake while using the VPN. The no-log policy ensures your data remains private at all times. Unlike VPNs, many proxy servers keep connection logs and even activity logs.
Some paid VPNs offer a more reliable connection than proxy servers. The VPNs also come with features such as kill switch and leak protection. These features ensure that your privacy and security are not compromised even when the connection drops. Furthermore, VPNs have many servers, and this avoids congestion.
With proxy servers, congestion and server overload may lead to connection problems.
Generally, a web proxy will perform poorly at unblocking geo restricted content. This is because most websites and apps with such content have long banned most public proxy services.
A premium VPN, on the other hand, is very good at unblocking and also has a fast connection speed.
But like a free proxy, a free VPN will also not work in most cases of blocked content.
Here are how VPNs and proxy servers can be similar:
VPNs and proxy servers suffer from slow speeds. In VPNs, slow speeds are due to the encryption overhead. In proxy servers, slow speeds are due to the ‘middleman’ and congestion/server overload.
However, in the case of premium VPNs this speed decrease is almost undetectable.
Proxies, on the other hand, are almost always very slow.
Both VPNs and proxy servers mask your actual IP address. Any entity on the internet will either see the VPN or proxy server IP address.
By masking your IP address, both VPNs and proxy servers help you gain access to restricted content. However, a VPN is more reliable in bypassing restrictions than a proxy server.
VPNs are suitable for the following tasks:

Proxies are suitable for the following tasks:
VPNs and Proxy servers are great tools for bypassing restrictions, hiding your IP address, and giving you privacy. However, each tool is best suited for different tasks. In a nutshell, a VPN gives you comprehensive functionality as compared to proxy servers.
Lastly, it is advisable to use paid/premium VPNs or proxy servers. They give excellent value for your money.
Do you need a proxy if you have a VPN?
No. A paid VPN can offer all the functionality that you get from a proxy server. A VPN will also provide other functionalities such as encryption, kill switch, leak protection, among many others. Additionally, a VPN doesn’t log your online activities.
Which is faster, VPN or proxy?
Although both may slow your internet connection speeds, a VPN has better overall speeds. Other than the encryption overhead, a premium VPN doesn’t suffer from server overloads and congestion.
Can I use VPN and proxy together?
Yes. However, for excellent results, ensure you have a faster internet connection. This is because of the encryption overhead, and the proxy might slow down your speeds. Although you might improve your privacy, you may or not miss other functionalities’ bypassing restrictions.
Using a proxy may negate your privacy enhancements your VPN offers.
Is a proxy server the same as a VPN?
No. A proxy server and a VPN are not the same. Nonetheless, they share some functionalities, such as masking your IP address.
Is using a proxy server safe?
A proxy server is not safe in terms of privacy and security. A proxy server doesn’t encrypt your traffic, and this makes it susceptible to prying eyes. Furthermore, proxy servers log your activities and even connection stamps. Others may push ads and malware.
