Cybercrime is an ever-growing issue in the online world. It is a jungle out there, so you need to be careful. Using a VPN will help you keep your identity secure, but it can also help you protect your data from others. Let us dig deep and understand more about VPN and its uses in cybersecurity in detail.
What is a VPN?
A Virtual Private Network (VPN) helps you connect your device to another computer network over the internet. The connection gets made through a virtual tunnel between the two networks, creating an encrypted connection. This encryption keeps your data from prying eyes, including those of your Internet Service Provider (ISP).
- VPN provides anonymity by hiding IP Addresses.
Internet Protocol addresses are unique numbers that identify your computer on the internet and can be used to track your online activities and website visits. When you use a VPN, the number is replaced with one from the VPN provider server so that no one can see what you are doing online.
VPNs are useful in organizations where employees work from home or travel frequently. They allow you to securely access your work email, documents, and other resources from anywhere.
What is the use of VPN in Cybersecurity?
VPNs are used in cybersecurity to protect the integrity of information and secure communications. They can create a Virtual Private Network (VPN) between two or more points on a network, allowing secure communication between connected computers. Businesses often use VPNs to allow employees to access internal systems remotely and who want to access their work networks from home.
For instance, if a company is headquartered in San Francisco but has clients and employees all over the globe, it needs to know that its data is secure when accessed from different places worldwide. From this standpoint, a VPN gets used by CEOs and other corporate executives who travel frequently or anyone who uses public connections to access sensitive data.
Let’s check the use of VPN in Cybersecurity:
1. Stop Getting Spied
VPN technology allows you to hide your IP Address and location. This way, if anyone wants to spy on you, they will not be able to do so.
Since your IP address is hidden, you can use services like Netflix or Hulu in places where it’s not available.
The reason why people use VPNs is that they want to safeguard their privacy. Internet browsing via a VPN is anonymous, so no one can see what sites you visit or what you transmit and receive.
2. Encryption
There are multiple reasons to use a VPN, but the most significant is that it allows you to make an encrypted connection to a server. It means that your traffic will be secure, and if someone were to intercept it, they wouldn’t be able to read what’s inside.
Since it’s encrypted, the data is also more challenging to detect by someone who might be monitoring your network. If the person notices something suspicious, it will look like gibberish as they do not have access to the key that would allow them to decrypt it.
3. Authentication
The authentication process involves verifying an individual’s identity and authorization to access a system or network. Cybersecurity users often use authentication to verify an individual’s identity and protect sensitive data, like credit card numbers and passwords, from unauthorized access.
A VPN can help to protect this process by creating an additional layer of security between users and their systems.
4. Securing your connection over public WiFi networks
Public WiFi networks are incredibly convenient, but they are also insecure at the same time.
If you are using one to connect to the internet at a coffee shop, hotel, or airport, you can not be sure whether your connection is secure by the coffee shop’s firewall or just the one built into your device.
Public WiFi connections can be secured using a VPN. If VPN sounds like something out of a science fiction movie, that’s because it is! VPNs create encrypted tunnels between your computer and the VPN server. You can think of it as having a private line connecting your computer to the internet: no one can see what data is coming through that line or decipher what’s happening inside it.

Wrapping Up!
Summing up the blog entitled Introducing VPN and Its Use in Cybersecurity: Exposed in one line, I would say that using a VPN is necessary to ensure a secure connection between the client and server.
VPN is required since data transmission is full of vulnerabilities when using the internet. The sender and recipients can access the data which passes through them. The sender can also alter the data getting transferred to other people.
VPNs guarantee the complete security of network services by encrypting the transmitted data and enabling only authorized users to access it.
