LC-Connect is the communication and collaboration component of the leitzcloud suite, operated by LC by vBoxx GmbH (Frankfurt am Main; part of the Dutch vBoxx group). It bundles business email, calendar, contacts, tasks, notes, and online video meetings into a single platform, with integration into leitzcloud storage so attachments can be sent as links or files from the user's cloud. The positioning is an integrated, German-hosted alternative to Microsoft 365 / Outlook (and Google Workspace) for businesses that want their communications and organisational data kept inside EU infrastructure.
Data is hosted exclusively in Germany on the group's own georedundant infrastructure, with ISO/IEC 27001 (TÜV Nord) certification, giving an EU-owned, EU-hosted, no-CLOUD-Act-exposure posture. Encryption is TLS in transit and server-side at rest — this is business groupware, not a zero-access end-to-end-encrypted mailbox like Proton Mail or Tuta, which is the right distinction for readers comparing on encryption model. The vendor provided an AVV (DPA, sub-processor list, data-residency statement) on request in June 2026; it is not yet published at a public URL. Best fit: DACH SMBs and public-sector-adjacent teams that want one EU-hosted environment for mail, calendar, and meetings rather than stitching together separate tools.
