HTTPS enforced with HSTS in Cloud storage
We measure this ourselves on their own site. It is the cheapest security control there is.
15 of 27 companies we measured here publish it, that is 56%. Last checked 2026-10-16.
56% here against 62% across every category we measure. Cloud storage sits below 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.
