Answering the question, “What is a VPN”, we can say that it is a technology that creates a secure and encrypted tunnel between your device and the server to which you connect on the Internet. Imagine that it is a secret tube that allows you to browse the Internet safely, protecting your personal information and browsing data from prying eyes.
How does a VPN work?
When you connect to a VPN, your device communicates with the VPN server , and the VPN server sends your information through that encrypted tunnel. This means that anyone trying to intercept that information will only see encrypted data.
For example, if you are in United Kingdom and connect to a VPN server in the United States, the websites you visit will think that you are browsing from the United States. This can be useful for accessing content that would otherwise be geographically restricted.
What is a VPN for: Advantages and benefits
Now that we have answered “what is a VPN” and how it works, let’s talk about what it is for. The main advantage of using a VPN is that it improves your online privacy and security. By encrypting your data, you prevent cybercriminals, your Internet Service Provider (ISP), and even the government from viewing your online activity.
Additionally, a VPN can be useful for:
- Bypass censorship and geo-restrictions: If content is blocked in your country, you can use a VPN to access it as if you were in a different location.
- Security on public WiFi networks: Public WiFi networks are notorious for their lack of security. With a VPN, you can protect your data even on these networks.
- Streaming and gaming: Some VPNs can help you avoid throttling from your ISP, improving streaming and gaming speeds.
Are all VPNs the same?
Although we have already defined “what a VPN is”, it is important to mention that not all VPNs are the same. There are free and paid VPNs, each with their own advantages and disadvantages. In general, paid VPNs tend to offer better speeds and greater security.
