Cryptomator vs OpenText Voltage SecureData Servers

Cryptomator encrypts files on the user's device before they go to a cloud storage service. Its AES encryption uses a 256-bit key and covers both file contents and filenames. The software is open source, with source code available for community security audits. It works with a cloud service of the user's choice; on desktop, access to vaults requires that service's sync software on the computer. Mobile apps natively support services such as Dropbox, Google Drive, OneDrive, pCloud, S3, and WebDAV, with availability varying by platform. The Android and iOS apps are currently incompatible with Mega, including through WebDAV. Free mobile versions are read-only; full access requires a separate one-time purchase for each platform. Cryptomator Hub adds user and group administration and zero-knowledge key management for teams, with OpenID Connect, SAML, and LDAP integrations. Cryptomator lists Android, iOS, Linux, macOS, web, Windows, and self-hosted platforms. The individual plan is free; optional upgrades are €29.99, paid once.
