Data protection has a particularly high priority at Profil M. In order to guarantee this in email traffic, we have implemented a SecureMail system that can encrypt and decrypt emails using various technologies.

Depending on which system is used in your company, we can set up a process with you through which personal data can be sent securely by email. The following solutions are possible:


We sign outgoing emails with corresponding certificates. You can also use our certificates from these signatures to encrypt your email correspondence to us.

Do you sign your email correspondence with public certificates? Then our system automatically saves your certificates and encrypts emails to you automatically using S/MIME.

Do you use your own PKI to issue certificates? Please contact us to compare your root certificate so that we can validate your certificates. For this purpose, a contact person from your IT department simply has to get in touch with our IT department. All emails will then be automatically encrypted from the time the certificates are compared.


All our PGP keys are signed with our master key and published on the SKS KeyServer network. Please check the PGP keys against our master key before using them.

You can download our master key here.

Are you able to you receive PGP-encrypted emails? Please send the public part of your PGP key as a PGP-encrypted email to, please use our master key for encryption.

We will contact you by phone to match the fingerprint of your PGP key.

Our system will then automatically encrypt emails to you using OpenPGP.

Encrypted PDF

If you neither use S/MIME nor OpenPGP, you will be prompted to choose a password the first time you receive an encrypted email from us. Our system then converts emails with confidential contents to an encrypted PDF file before they are sent to you.

You will then receive this encrypted PDF file by email and can open and view it with the password you selected.

Please use Adobe Acrobat Reader or Foxit Reader to open the PDF file..
