security.txt (RFC 9116) in E-signature

It tells a researcher where to report a vulnerability instead of guessing.

6 of 30 companies we measured here publish it, that is 20%. Last checked 2026-10-16.

20% here against 11% across every category we measure. E-signature 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.
