Do you have a general inquiry about our services or websites?
Please feel free to use our contact form.
You have the option of exchanging encrypted e-mails with us using S/MIME or PGP.
If you sign and/or encrypt your emails using S/MIME, we receive your public key as soon as you send us an email – this email is not yet encrypted in content! As soon as we reply to your email, it is automatically encrypted with your public key – the content is now encrypted and protected! You will also receive our public key with this email – at this point, all emails we exchange are encrypted!
If you received an email from us first, it was already signed using S/MIME. You will then receive our public key first – but the content of this email is not yet encrypted! If you reply to this email and use S/MIME, our public key will be used – this email is now encrypted and the content is protected!
If you have doubts about the authenticity of our S/MIME certificates or they are rejected by your system, please contact us. We will arrange a telephone appointment with you to match the fingerprints and confirm the authenticity of the certificates.
If you want to use PGP for encryption, please contact us. We will set up the encryption and provide you with the public key afterwards.
You have the possibility to share files with us in a secure way (data room, fileshare). We provide you with our Nextcloud, which is hosted by a german provider in german data centers.
Upload / Download
If you want to transfer files to us (upload), we will provide you with a link to an inbox. This also applies in the event that we share files with you (download). We will coordinate the further procedure (e.g. password protection, file rights, etc.) with you separately.
If we need to exchange files with you on a permanent basis, it is possible that you will be given a user account. Please note that this user account is created per natural person. We can set up multiple user accounts for a company if required – collective or group accounts are not possible. For the creation of the user account, the data subject needs his or her own e-mail address.
If you have any questions about email encryption or secure file exchange, please feel free to use our contact form or send an email to firstname.lastname@example.org.
