In addition to protecting personal messages with end-to-end encryption, WhatsApp empowers users to control their own privacy settings: from what you share, how you show up online, or who can reach out to you or add you to groups. In end-to-end encrypted messengers like WhatsApp, clients are the source of truth.

The private nature of MPLS allowed an organization to not encrypt MPLS traffic, a big benefit in terms of encryption key management and required CPE (customer premise equipment) capabilities. The immediate concern is encrypting the internet tunnel of the SD-WAN solution. However, SD-WAN or MPLS arent security solutions.

VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection. VPNs can also be set up using L2TP/IPsec protocols, which proves to have much stronger encryption than PPTP.
