A virtual private network, or VPN, is a service that allows you to communicate over a public, unsecured, unencrypted network privately and safely by establishing secure, encrypted connections

Amid Covid-19, most of them have switched to online transactions, purchases which gives a rise to online fraud and also an opportunity for hackers to steal your data.

VPN uses encryption technologies, such as IP security,  Layer 2 Tunneling Protocol and Secure Sockets Layer and Transport Layer Security to create a virtual encrypted “tunnel” between your device and a VPN server.

The tunnel prevents hackers, snoopers, and internet service providers (ISPs) from looking at your instant messages, the browsing history, credit card information Wireless connections, especially public access points, are particularly vulnerable to sniffers, or computer programs that are used to decode data to make it readable.

A VPN can help to protect your computer and your information from sniffers and other types of hacks

Without a VPN, your internet service provider can know your entire browsing history. With a VPN, your search history is hidden.

People turn to a VPN service for online privacy as these companies enable you to create a VPN between your gadgets and their internet destinations.
