Why is VPN important for network security?

• A virtual private network (VPN) is a type of internet security and privacy technology. When you use a commercial VPN service, you use an encrypted connection to connect to a VPN provider's server. In other words, all data sent between your computer and the VPN server is scrambled and cannot be read by anyone else.
• This configuration has a variety of critical implications, including significantly increased Internet security.
• All activity is hidden from your Internet service provider since your data is encrypted (ISP). Because your VPN provider can monitor your online behaviour, VPNs should always be thought of as providing privacy protection rather than anonymity.
