What is VPN & How Can It Secure Your Data?

A VPN or a Virtual Private Network is able to secure the data that you send and receive by encrypting them. Companies often make use of VPNs to link data centers and offices that are not on the same physical network. But they are also used by individuals in order to keep communications and other online activities private on untrusted or unsafe public networks.

A lot of organizations and corporations put VPNs in place in order to give offsite employees or staff a secure connection to an office facility’s Local Area Network (LAN). A VPN is enabled by launching a VPN client application on the employee’s device for example, and then logging in with the necessary details. The device then exchanges trusted digital keys with the remote server, and once both devices verify each other’s authenticity, all data and communications that travel between them will be encrypted and secure from eavesdroppers or hackers (even if an untrusted internet connection is used).  VPNs work by tunneling. Through tunneling, Internet Protocol (IP) packets are encapsulated within other packet formats. This allows original data to be hidden from anyone attempting to pry.

Other people get VPNs for their ability to provide access to services or websites that are geographically restricted. With the help of a VPN, the streaming server in a remote country will see your connecting device as being in a non-restricted area. Having a VPN can also protect all the other information that you share in your online activities, such as your account number, address, card number, etc. Even your internet calls will be kept private. Whatever platform you’re using, your voice messages will be automatically encrypted so that no one can eavesdrop on your private conversations.

When looking for a VPN provider, it is important to consider one that has server locations across the globe, encrypts your connection with military grade AES 256-bit, and doesn’t log your data.
