No firm pays to be rankedThe index takes no money from firms or vendors. Paid evaluations, when they come, will never feed the public scores.
Every mark links to its sourceOpen any blue or orange mark to see the page it came from. Nothing self-reported counts as confirmed.
Firms can add evidenceSend a public link for any check. Independent sources count in full once verified. The firm's own pages count as "the firm says so".
