Example: Marketing Company Sharing Sensitive Data with Customers

  • Large amounts of data have to be easily sent via Microsoft Outlook, because employees cannot be trained separately and mail servers usually have an average email quota of 50 MB (in this case trailers, videos and large marketing folders are sent)
  • Data must be encrypted before leaving the contractor and must arrive at the client’s premises in encrypted form
    It must be clear who can decrypt this file
  • To how many users was the file sent to
  • The client must also be able to provide the contractor with encrypted files (corrections, orders,…)
    It must be possible to check whether the user has already registered for the encrypted data exchange
  • In this example, the customer of the marketing company must meet the following criteria in order not to violate the internal compliance guidelines

Our solution meets all requirements!


  • Data transfer with E2EE for ownCloud creates a high security added value for all companies and persons who work with sensitive and personal data or want to securely exchange data with third parties.
  • Neither the sender nor the recipient need any special software on the computer. All functions are covered by the web browser (Edge, Chrome, Firefox, Safari, Opera).
  • The guest function integrated in ownCloud enables a previously invited recipient to provide the sender with encrypted files.
  • E2EE ensures that data can only be read by the intended recipients.
  • Man-in-the-middle protection – even server administrators have no access to the data.
  • Users who receive E2EE-encrypted data outside the licensed organization do not need an additional license.
  • Due to the hybrid encryption method, no special certificates are required. There is a locally stored private key and a public key (RSA). This key exchange of the public keys is completely taken over by the plugin.
