Using a VPN for accessing different websites is common in today’s world. But what is VPN?

VPN or Virtual Private Network can be described as a way of establishing protected connectivity through private networks. The VPN uses encryption to disguise one’s identity and web traffic. Such encryption ensures that no third party is able to detect your online activity or hack your data. It involves real-time data encryption.

Thus, the ISP and other users are unable to detect your online activity. VPN is the ideal filter that changes your online data to “gibberish,” making it useless to hackers.
