We use Secudoc to guarantee the safe transfer of larger files and documents. If you want to send your files via Secudoc, please send us a request by email. You will then receive an email with a link that leads to the Secudoc upload page. After you upload your files, we can download your uploaded files only by using two-step verification. This provision is especially practical with a larger number of attachments or large files that cannot be sent in one e-mail.
