Alternatives to Open-Xchange
Other Email hosting vendors we measure, sorted by how much they publish that Open-Xchange does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 23 that differ from Open-Xchange on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Open-Xchange has 11 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Status page with history, Public pricing, Certifications named, Uptime SLA with a figure, HTTPS enforced with HSTS, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “publishes and Open-Xchange does not” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
