I Protect

Secure Transmission and Storage of Opolis E-Mails

Opolis is a high-security E-Mail service. The Power to the Sender concept of Opolis allows the sender to protect, control and monitor all sent messages. With Opolis, it is always the sender of an E-Mail who has ultimate authority and control over the flow of messages and its attachments.

The "I Protect" feature is the most important core element to the Opolis service: Opolis combines the latest E-Mail security technologies and transmits, processes and stores all your confidential messages in encrypted mode. Opolis also ensures that neither message content nor information in relation to the message flow can be manipulated or falsified. And finally, the encryption methodology used by Opolis has never been hacked before.

The rationale for Opolis: When an E-Mail is sent with a standard E-Mail application, then usually the sender loses all authority over the E-Mail and its content the moment the Send button is pressed. In standard E-Mail applications messages and attachments are not sent encrypted and can therefore be intercepted and read, in particular when a message is interim-stored on one of the many servers on its path to the recipient. In worst cases - once sent - E-Mails can be manipulated: The main content of a message can be manipulated by an interceptor, but also by the recipient. Also, the transmission flow information regarding the message (e.g. when it was sent) can be manipulated. And, all this can happen without the originator of the message even knowing. - Or, trying to pull back an accidentially sent message before it is opened by the - alas, wrong - recipient is virtually impossible, once several servers were involved in the transmission, as is the case with standard E-mail applications.

Secure Data Transmission

  • All information and data transmitted via Opolis, hence all Opolis E-Mails, are sent point-to-point from the Sender to the Recipient only in encrypted mode. This means that information and data sent cannot be interpreted by any unauthorised third parties, but only read by the Sender and the Recipient of an Opolis E-Mail

  • Opolis uses asymmetric encryption, also known as Public-Private Key technology, and the services of iTrust as a registry of public keys for Opolis Users. Public-key encryption is a cryptographic system that uses two keys:
    - Each User is allocated a public key which is accessible to every Sender of an Opolis E-Mail to this specific User to encrypt messages.
    - The corresponding private key used to decrypt an Opolis E-Mail (i.e. make it legible) is only and exclusively known by the Recipient an Opolis E-Mail.

  • Please Note: The encryption methodology used by Opolis has never been hacked before.

  • Please Note: Also Opolis as a service provider is not in a position to decrypt and read any Opolis E-Mails

  • And finally: The unique architecture of Opolis does not allow any manipulation to a content of a message once it has been sent. Neither is a manipulation possible in regards to the transmission flow information of the message (e.g. when it was sent)

  • Secure Opolis E-Mail Server System

  • Opolis operates several Opolis E-Mail server systems across the globe where information and data are stored, processed and retrieved simultaneously

  • As all information related to Opolis stored and archived on these servers is in encrypted format only, an unauthorised third party is not able to read or interpret Opolis E-Mails and information attached to them
