Documents you upload are never passed to third-party services for virus scanning or AI processing.
Defense Against Internal Threats
Unencrypted data is processed exclusively in data-cleanup areas (without persistent storage) to prevent leaks from internal attacks.
Defense Against External Threats
Systems are hardened; server OS is locked down; electro-mechanical door monitoring is in place.
Operating Models: Flexible to Your Needs

360°- Protection
Sealed Cloud (German: versiegelte Cloud) delivers complete protection across the data lifecycle. Transmission (“data in transit”), storage (“data at rest”) and processing (“data in use”) are all secured—a capability beyond what typical security models can offer.
Metadata such as file names, user IDs, creation and modification timestamps are hidden from unauthorized view, setting Sealed Cloud apart as one of the most secure technologies for protecting sensitive information.
