What is a VPN?


VPN makes you access to the Internet more private and secure

Have you been so comfortable with the idea that your private data is being transmitted over Wi-Fi, so that you no longer have to worry about the security of the data, and no longer worry about who else will spy on it, or even steal it for malicious purposes? If so, unfortunately you are the majority, you should consider using a virtual private network, or a VPN. Even those who support network neutrality — you might think they know a lot about technology and privacy issues — only 45% of them have been used a VPN.

This attitude toward personal data security and privacy represents a huge cybersecurity issue. Public Wi-Fi networks, which are open and convenient, unfortunately, are also very convenient for attackers seeking to damage your personal information.

Even if you tend to trust your companion ( I don’t recommend it ), you should not trust your Internet service provider.

In short, it’s time to start thinking about protecting your personal information. This is where virtual private networks (VPNs) play a role. These services use simple software to protect your internet connection。Although you may have never heard of VPN services, they are a valuable tool you should know and use. So who needs a VPN? Well, everyone needs it.

What is a VPN?

A VPN creates a secure and encrypted connection ( which can be thought of as a tunnel ) that connects between your computer and the server operated by the VPN service. In a professional environment, this channel effectively makes you being part of the corporate network as if you were sitting in the office.

When you connect to a VPN, all network traffic goes through this protected channel, and no one—even your isp—can see your traffic until it exits from the tunnel of the VPN server and enters the public internet. If you can make sure you only connect to websites that use HTTPS, your data will continue to be encrypted even after your data leaves the VPN.

Think this way: If your car drives out of the driveway, someone will follow you, see where you are going, how long you stayed at the destination, and when you will be back. They can even peek into your car and learn more about you. But through the VPN service, you basically drive into a closed parking lot and switch to another car to drive out, so no one knows where you are going.
