The features offered are advanced key management, easy and secure end-to-end encrypted sharing, Cryptographic Identity Protection and support for business capabilities like HSM support and an offline administrator recovery key.
"Nextcloud is first to offer seamless, integrated end-to-end encryption in its clients as part of a complete enterprise class file sync and share solution", said Nextcloud founder and managing director Frank Karlitschek.
"Secure yet easy key handling between clients and users with enterprise key management and recovery options set this solution apart from others."
The end-to-end encryption feature is designed so that the server never has access to unencrypted files or keys.
Server-provided code never handles unencrypted data which could provide avenues for compromise.
User interaction is not needed and key-sharing is handled by the server, facilitating completely intuitive sharing and collaboration.
The code is open source and Nextcloud is seeking third-party review and audits as part of an extensive testing period until the Nextcloud release.
"Organisations that demand the utmost security need a true enterprise solution that doesn't require users to manually exchange encryption keys and long, complex passwords or share large, encrypted volumes," said Lukas Reschke, security team lead at Nextcloud.
"Nextcloud 13 will be first to market with an integrated, secure technology to keep a subset of highly sensitive files cryptographically secure even in the worst case of an undetected, full server breach."
