Email security vendors, ranked by what they publish

Email security and phishing defence, ranked by what they publish about how they handle your data.

12 vendors measured on their own sites, last on 2026-09-02. 10 ranked, 2 without enough data for a score. A vendor we could not measure often enough gets no rank at all, rather than a bad one.

Public transparency score, not a product or security rating. Transparency means: published on the vendor's own site, readable without a login, found by us at the addresses we checked.
