HTTPS enforced with HSTS in Mass notification and critical events
We measure this ourselves on their own site. It is the cheapest security control there is.
25 of 41 companies we measured here publish it, that is 61%. Last checked 2026-10-17.
61% here against 62% across every category we measure. Mass notification and critical events 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.
