Do background checks to verify potential employees rely on profiles data brokers have compiled on them? Or do background checks rely on more direct means?

I run background checks for employment regularly and have used multiple different providers. Never seen data broker information. Largely the providers I’ve used have in advanced let me know which county courthouses they would collect information from.
Thank you for the reply! I appreciate the insights provided.
