Have you ever thought about whether someone can read your emails? It can be negligent to send emails unencrypted, especially when it comes to confidential data. This is because it is easy to intercept data from these emails and misuse them for your own purposes. You can imagine an email like a postcard - anyone who holds it in their hands on its way to its destination can read it. An encrypted email can therefore be a solution.
Not only private individuals, but also companies are quite careless when it comes to sending emails. According to an analysis by TÜV Süd, 52 percent send unencrypted emails at least sometimes and 21 percent never encrypt their emails. This is particularly fatal in view of the GDPR that has just come into force and the recurring data scandals. And let's be honest, nobody wants their sensitive data, such as their bank account details or date of birth, to be floating around the Internet somewhere.
Particularly in the context of GDPR Article 32, companies are iceland number dataset obliged to establish suitable technical and organizational measures as controllers and processors in order to ensure an appropriate level of protection for personal data. Emails containing confidential data should therefore be encrypted. On the one hand, so that the company continues to be perceived as reputable, and on the other hand, so that there is no need to fear any legal consequences.
What options are there?
In order to send emails securely, it is advisable to use standardized systems. Using these communication systems offers the great advantage of compatibility with other systems, such as those of your customers and partners. In addition, they are often already integrated into existing email solutions.
transport encryption SSL/TLS
With transport encryption, it is not the email itself that is encrypted, but the transport path through the Internet. This is possible with Transport Layer Security (TLS) or its predecessor Secure Socket Layer (SSL). With this technology, the sender and recipient of an email build an encrypted tunnel together. The servers on both sides form an intermediate station. TLS is a combination of the symmetric encryption method, in which the sender and recipient use a common, secret key, with asymmetric algorithms. This guarantees secure and reliable data transmission. The disadvantage, however, is that the sender can only guarantee encryption on the way from him to the server and from server to server. It is therefore possible that the transmission from the server to the recipient is unencrypted. In addition, the email is unencrypted on the respective server. This means that there is a certain residual risk that hackers can still access the contents by manipulating the data.
The EMM also sends all emails via TLS by default, thus ensuring the best possible protection for marketing emails.
