Can I send highly sensitive data via email?
Generally speaking yes as the email-channel established itself as the main instrument for exchanging information in daily life in the last years. This led to the fact that legislation has been more strict and regulated the handling of highly sensitive data such as personal information, health data, financial data, and much more.
One of the core requirements by many data privacy acts around the globe is that highly sensitive data sent by email must be transmitted with highest protection measures. The data protection requirements are fulfilled by encrypting either the email itself or ensuring the secure transmission of the email (transport encryption). Adhering to data protection enables parties to communicate by email in a legally compliant manner.
