security.txt (RFC 9116) in SEO tools
It tells a researcher where to report a vulnerability instead of guessing.
2 of 44 companies we measured here publish it, that is 5%. Last checked 2026-10-15.
5% here against 11% across every category we measure. SEO tools 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.

We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
