Reading the ranking
Only categories with at least 20 listed companies are ranked, so a single certified vendor cannot carry a sector. The uncomfortable rows are near the bottom: Accounting & Tax sits at 18%, and Cybersecurity, an industry whose product is assurance, runs below the 38% baseline it sells against.
