security.txt (RFC 9116) in Library systems
It tells a researcher where to report a vulnerability instead of guessing.
2 of 33 companies we measured here publish it, that is 6%. Last checked 2026-10-17.
6% here against 11% across every category we measure. Library systems 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.
