Except for the regular ISO 900 1, 1400 1, 1800 1. Now there are ISO2700 1 27k on information security, which pay attention to the information security risks in the river and reduce them to an acceptable level. There are generally these industries that need 27k certification, including IT, R&D, software, OEM, ODM, advertising and printing, intellectual property, personal information training, personnel, hospitals, medical care and banking. I don't know if that's what you're talking about In addition, IS02000 is about information security. Unlike 27k, 20k is aimed at the service industry and IT, while 27K is needed by all industries and has higher security. 20k is for quality and 27k is for risk.
