Written by Daily Fix - Published 08-Jun-2023, last updated 08-Aug-2024
A VPN, or virtual private network, is a service that encrypts your internet traffic and routes it through a secure server via a secure encrypted connection. This makes it much more difficult for third parties to track your online activity or steal your data.
What is a VPN used for?
VPNs are used for a variety of purposes, including:
Using a VPN for security
VPNs can help protect your privacy and security online. By encrypting your network traffic, they make it much more difficult for hackers to steal your data or track your online activity. This can be especially important when you are frequently connecting to WiFi networks outside of your home network or office, such a public networks in coffee shops.
Using a VPN for anonymity
VPNs can help you maintain your anonymity online. By hiding your IP (internet protocol) address, they make it more difficult for websites and other organizations to track your location and browsing habits.
Using a VPN to block content
VPNs can be used to access blocked content. For example, if you're traveling to a country with strict censorship, you can use a VPN to connect to a server in another country and bypass the censorship.
Why use a VPN?
There are many reasons why you might want to use a VPN. Here are a few of the most common VPN benefits:
Using a VPN to protect your privacy
If you're concerned about your privacy online, a VPN can help. By encrypting your internet traffic and hiding your real IP address, a VPN can make it much more difficult for third parties to track your online activity.
Using a VPN to secure your internet connection
If you're using public Wi-Fi, a VPN can help protect your internet connection from hackers. By encrypting your traffic, a VPN can make it much more difficult for hackers to steal your data from your laptop or mobile devices. Personal VPNs secure data transfer by sending encrypted information so that your private data is hidden from internet service providers and people trying to intercept your online traffic or online identity.
Using a VPN to access blocked content
If you're traveling to a country with strict censorship, a VPN can help you access blocked content. For example, if you're traveling to China, you can use a VPN to connect to a server in another country and bypass the censorship.
Using a VPN to get around geo-restrictions
Some websites and streaming services are only available in certain countries. If you're not in the right country, you can use a VPN to connect to a server in that country and access the content.
How does a VPN work?
A VPN works by creating a secure tunnel between your device and a remote server. When you connect to a VPN, your traffic is routed through this tunnel, which is encrypted - this is known as an encrypted tunnel. This makes it much more difficult for third parties to track your online activity or steal your data.
The remote server that your traffic is routed through is owned by the VPN provider. The VPN provider then decrypts your traffic and sends it on to its destination. The VPN provider does not store any of your data, so your privacy is protected.
How do you use a VPN?
To use a VPN, firstly you need to choose a VPN provider (more on this later). Once you have done your research and you've chosen your VPN provider you will need to:
Download and install the VPN software
The VPN provider will provide you with a link to download the VPN software for your computer or device. Once you've downloaded the software, install it according to the instructions. The VPN software for use on your laptop will probably may be available from the VPN provider's website, but mobile VPN apps will be available through your chosen app store. This softwware is known as a VPN client.
Create a VPN connection
Once the VPN software is installed, you'll need to create a VPN connection. This usually involves entering your VPN username and password, and selecting a VPN server location.
Connect to the VPN
Once you've created a VPN connection, you can connect to the VPN by clicking on the "Connect" button. Once you're connected to the VPN, your traffic will be routed through the VPN server, which will hide your IP address and encrypt your traffic.
It is also possible to configure some touters with the VPN settings so that all internet traffic generated within your network is automatically routed through your chosen VPN. Look in your router settings for an option such as router VPN settings or VPN services.
