Notice before subprocessors change in Data catalogs and governance
A list is a snapshot. Art. 28(2) GDPR gives you a right to object, and that needs advance notice.
5 of 25 companies we measured here publish it, that is 20%. Last checked 2026-10-18.
20% here against 10% across every category we measure. Data catalogs and governance sits above the overall share for this criterion.
This page counts companies, not product entries: a company with two products in this category is one company here and two rows below.

Not measured
We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
