Some websites include malware, online trackers that advertisers use to target us, internet service providers that sell our browsing information to the highest bidder, and the spying capabilities of government organizations. Check out this ExpressVPN review for a secure browsing session.
The Function of VPNs
VPNs function by linking the user to a private server rather than a public server. The user is far less likely to be hacked using a public Wi-Fi network thanks to the Private server, which encrypts their web traffic and activities in a tunnel and changes their IP address.
For customers to connect as locally as possible, most VPN providers have servers spread out over the globe; the closer the server, the better the connection speeds. Some VPNs even perform a method known as “multi-hop,” which encrypts user communication multiple times through various servers.
The most recent industry standards for encryption, including AES-256, SSL (or Secure Socket Layer), and SHA 2 (or Secure Hash Algorithm), are used to protect web traffic. The user’s data delivers to the server via VPN protocols after the VPN has created the encrypted tunnel. Of course, the user is unaware of this as soon as they click “connect,” encrypting their web traffic and masking their IP address.
