What to expect in the guide
Email is indispensable – and at the same time one of the biggest risk factors if it is not properly protected. Basic protection with TLS is not sufficient for sensitive data, and in regulated industries standards such as S/MIME have long been mandatory.
The guide provides clarity: it explains the common methods of email encryption, outlines clear criteria to show which solution is suitable in which situation, and uses typical use cases to highlight what really matters in practice.

Clarity instead of uncertainty
It is often unclear which method is truly suitable. The type of data, the group of recipients, regulatory requirements and other factors make the decision complex and lead to uncertainty among users.
The guide therefore offers a visual decision-making aid: by answering targeted questions, you can identify the right encryption solution step by step. This way, you can quickly see whether basic protection with TLS is sufficient for your purposes, S/MIME is required, or a platform solution such as FTAPI is the best choice.
