With the ever-evolving cyber threats, privacy protection online is more emphasized than ever before. Your information is at risk of attack by hackers, advertisement, or third parties that you have no control over whenever you are using the Internet, accessing critical business information or even accessing plain Wi-Fi. Here comes the Virtual Private Network (VPN).
Have you ever questioned yourself on what is a VPN, how VPN works and do you need one then this guide will provide you all the answers. We will explain what VPN will mean in its entirety, its benefits, the different types of VPN, and how it compares to other privacy tools.
What Is a VPN?
A Virtual Private Network (VPN) is a computer security system that establishes a safe and encrypted tunnel between the computer and the web. Your computer internet traffic is redirected through a VPN server instead of connecting to websites or online services directly, such masking your IP address, and protecting your data information against being stolen.
Simply, a VPN is a secure route that assists in maintaining the privacy as well as security of your online activities.
VPN Full Form
The full name of VPN is Virtual Private Network.
- Virtual: Operates digitally over the internet.
- Private: Encrypts and protects your online data.
- Network: Creates a secure connection between devices and servers.
VPNs are exercised by most people, companies, working at a distance and even organizations that require secure access to the internet.
How VPN Works
Understanding how VPN works is easier than it sounds.
When you connect to a VPN:
- Your device connects with a VPN server.
- The internet traffic is encrypted by the VPN.
- Your real IP is not displayed.
- The VPN server uses its IP address when using websites and internet services, rather than yours.
- Information is transmitted through a coded passageway before it reaches its destination.
This makes it difficult to be tracked on the internet by hackers, the internet service providings (ISPs) and other third parties.
How Does VPN Work in Practice?
Suppose that you are in a coffee shop using public Wi-Fi. It poses a risk that you data may be intercepted by cybercriminals who are on your network unless you utilize a VPN.
When VPN is running:
- Your connection is encrypted.
- Confidential data is secure.
- Your identity is masked online.
- Transfers of data are safer.
This explains why VPNs are highly advised during remote working, using online banking, and using untrusted networks.
What Is the Use of VPN?
The question many people ask is what contributions does VPN have outside concealing an IP address? Privacy is just the tip of the iceberg.

What Is a VPN Split Tunneling?
Split tunneling is one of the highly developed VPN functions users may come across.
But what do you mean by a VPN split tunneling?
Split tunneling can be used so that a part of the traffic that uses the VPN will be routed through the server, and you still have other internet traffic that is not routed through the VPN but directed to the internet.
Example
You may prefer to:
- Securely route business applications through VPN.
- Stream or browse local websites without encryption by VPN.
Benefits of Split Tunneling
- Improved network performance
- Reduced bandwidth consumption
- More control of internet traffic.
- Enhanced usability of particular applications.
Nevertheless, it must be properly implemented in split tunneling by organizations in order to observe the level of security.
What Is a VPN vs Proxy?
Some of the privacy solution services, which are thought of by many users, include VPNs and proxy servers. Knowing the distinction between a VPN and a proxy may make you make the right decision.
| Feature | VPN | Proxy |
| Encrypts Data | Yes | Usually No |
| Hides IP Address | Yes | Yes |
| Protects Entire Device | Yes | Usually Browser Only |
| Security Level | High | Moderate |
| Suitable for Sensitive Data | Yes | Limited |
| Public Wi-Fi Protection | Yes | No |
The primary aim of a proxy is to hide your IP address, but a VPN will cipher your entire internet connection, which is safer and more certain to offer privacy.
