The Consumer Financial Protection Bureau (CFPB) is an agency of the United States government responsible for consumer protection in the financial sector. CFPB's jurisdiction includes banks, credit unions, securities firms, payday lenders, mortgage-servicing operations, foreclosure relief services, debt collectors, and other financial companies operating in the United States. Since its founding, the CFPB has "engaged the 21st century" by using technology tools to monitor how financial entities used social media and algorithms to target consumers.[3]:531–532, 537
