security.txt (RFC 9116) in Investor relations and disclosure
It tells a researcher where to report a vulnerability instead of guessing.
1 of 27 companies we measured here publish it, that is 4%. Last checked 2026-10-18.
4% here against 11% across every category we measure. Investor relations and disclosure 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.
