Email encryption is an authentication process that prevents messages from being read by an unintended or unauthorized individual. It scrambles the original sent message and converts it into an unreadable or undecipherable format. Email encryption is necessary when sharing sensitive information via email. 

Advantages of email encryption

While emails are a boost to businesses across industries, they also possess a great risk if data security is not taken care of. Email encryption helps organizations to ensure utmost data security. Below are a few advantages of email encryption:

Privacy And Security
Encryption ensures that your data is not compromised right from the moment it is sent till it is received. End-to-end email encryption prevents data theft even when at rest. Only the recipients who have a private key to decrypt the email will be able to read the message.
Both symmetric and asymmetric encryptions require a key to decrypt the email before it can be read by a user. This authentication process does not allow unauthorized personnel to view your sensitive information.
Regulatory Compliance
Owing to the obvious threats/risks that exist in today's world, most regulatory authorities like HIPAA, GDPR, etc. demand data to be encrypted. Due to this, most email providers support different email encryption techniques.
