comcrypto MXG is an email gateway from comcrypto GmbH that automates sending encrypted email. In the background it checks which protection the receiving mail server supports, applies transport-level or content-level encryption, and falls back to a password where necessary. S/MIME can be used for selected recipients, and every delivery is logged as proof of hand-over. The product is aimed at companies, public bodies, healthcare and education organisations, works with any mail client and includes an Outlook add-in. It is delivered as a cloud service (MXG Cloud), with on-premises hosting available as an add-on.
comcrypto GmbH is based in Chemnitz, Germany, and says it develops the software entirely in-house. On request, comcrypto can operate the service in the IONOS cloud, a German provider with data centres in Europe and the United States. The website does not state the exact location of the default cloud service. No owner outside Europe has been identified. For a European organisation this means a German supplier with the option of running the gateway on its own infrastructure.
