Is Mimecast EU-sovereign?

No. Mimecast is operated from the United Kingdom, outside the EU, so staysin.eu classifies it as non-EU.

Owned by private equity firm Permira since 2022.

How staysin.eu classifies Mimecast

A provider counts as EU only when all three criteria hold:

  1. Country: the operating company is based in the EU. Mimecast is operated from the United Kingdom (outside the EU).
  2. Holding: no non-EU parent or holding company.
  3. Own infrastructure: it runs its own stack rather than reselling a non-EU service.

Where a server physically sits is shown on each check but does not change the verdict: legal reach follows who controls the processing, not where the bytes are. Read the methodology.
