What is VPN (Virtual Private Network) used for

How Safe is it to use a VPN?

Virtual means fake, Private is not a public network, in other words, some companies set up their own private servers and provide services. It is called a Virtual Private network because it provides a secure connection between the Internet and your device and transmits data.

Why use a VPN?

If you are traveling on a public network provided by your airport or hotel, sending sensitive information, such as a public network, many people will use the same network. It is not safe for hackers to operate on the same network, so it is easy to steal information because your data is not encrypted. This is from a security perspective.

Another is privacy. For example, if you are traveling to China, you will not be able to access Facebook, YouTube or Google because it is banned. If you can see it, you can see that they are trying to connect this device to this site. You can trace your device ip and see your location, so you can block the internet on your device or ban the wifi devices you are using.

Another is accessed. If you watch Netflix in Myanmar and watch an episode from the US or Europe, it may vary depending on your location. For example, if you watch US IP and Netflix, you will see a library that users in the US see. Depending on your IP, access will be different, so the view will be different from place to place. The answer to these problems is VPN. In other words, using a VPN can easily solve security, privacy, and access issues.

How a VPN works

How does a VPN work? For example, if I watch Netflix, I would assume my device is Point A, the Netflix server is Point B, and the VPN is Point C. If you do not have a VPN, Point A will have direct access to Point B. If you use this type of direct connection, Point A will know point B, point B will know the IP address and location of Point A. Because you can access these IP addresses, your privacy will not be guaranteed. If you use a VPN, it works as an intermediate computer between Point A and Point B, so you have to go through the VPN instead of working directly. When a VPN receives data from Point A, it encrypts it and sends it to the server, in other words, Point B.

The data sent back to Point B is also encrypted and sent to the VPN (Point C). The data is decrypted through Point C and given to Point A. This VPN builds a secure tunnel between point A and point B, ensuring 99% data security. Even if you have hacked data, it will not be easy to read because it is encrypted data. Even the most advanced hacker is very difficult to decrypt. This allows the VPN to create a secure tunnel between your device and the server, so the server will not be able to see your device IP, and only the IP sent by the VPN, which will completely invalidate your privacy and security.You can also use VPN to address access issues if you are sensitive to data, blocked by location, or use a website that you do not want to expose yourself to. In short, using a VPN can solve security, privacy, and access issues.
