Subprocessor list in E-signature
Naming the actual subprocessors is what turns a privacy promise into something you can check.
4 of 30 companies we measured here publish it, that is 13%. Last checked 2026-10-16.
13% here against 7% across every category we measure. E-signature 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.
