End-to-end encryption protects electronic messages during the complete transmission between people, applications or devices. The messages are fully encrypted all the way from the sender’s client to the recipient’s inbox. Not only are the messages protected during transmission but also while they are being stored.
In a corporate environment, however, standard end-to-end encryption is difficult to achieve. Every user needs to possess a certificate of the designated recipient. The management of these certificates eventually becomes overwhelming.
Certificates cannot be centrally validated and encryption cannot be applied in a standardised homogeneous manner. This means that security processes are outsourced to individual employees instead of being managed centrally.
