HTTPS enforced with HSTS in Payment processing

We measure this ourselves on their own site. It is the cheapest security control there is.

30 of 36 companies we measured here publish it, that is 83%. Last checked 2026-10-16.

83% here against 62% across every category we measure. Payment processing 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.
