A virtual private network (VPN) is a service that connects an end user directly to a remote private secure network and its assets. The VPN hides the user’s IP address providing anonymity and privacy. Additionally, VPN connections are secured with encryption, preventing eavesdropping.
The main purpose of a VPN is to hide your online activity. VPN services are often used to guard against hackers and those who snoop on public networks, but they’re also useful for hiding your IP address, browsing activity, and personal data on any network — even at your home.
VPN is highly recommended in any case, especially working with sensitive data. You should stay connected to the VPN most of the time to keep yourself safe from data breaches, hackers, leaks, and snoopers such as ISPs or advertisers. VPNs encrypt your traffic and protect your privacy from third parties and cyber criminals.
