What is VPN (virtual private network)?

A Virtual Private Network, also known as a VPN, gives you online privacy and anonymity by creating a private network from a public Internet connection. VPNs mask your Internet Protocol (IP) address so that your online actions are virtually untraceable. Most important, VPN services establish a secure and encrypted connection to provide greater privacy.

How does VPN work?

A VPN extends a network through an encrypted connection made over the Internet. Because traffic is encrypted between the device and the network, traffic remains private throughout the journey. An employee can work outside the office and still be securely connected to the network. Even smartphones and tablets can connect via VPN.

It's important to remember that a VPN can't help if you download a malicious file, tricked you into entering your personal details on a scam website, or if you're using an identifiable account such as a Google account. You are logged in with an account that can be traced back to you regardless of your IP address.

Also, remember that the VPN service knows which websites you are visiting. Therefore, it is important to trust your provider. Paid VPN services such as NordVPN or Surfshark VPN will charge you a subscription fee, offer additional features, support for multiple devices, and better speeds. Free VPN apps and services often limit you to low speeds and may misuse or sell your data.
