Subprocessor list in API security
Naming the actual subprocessors is what turns a privacy promise into something you can check.
2 of 20 companies we measured here publish it, that is 10%. Last checked 2026-10-17.
10% here against 7% across every category we measure. API security 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.

We reached at least one address for each of these vendors and none of them carried it. That is what we found at the addresses we checked, on the date we checked them, and not a statement about what the vendor has.

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.
