Verify if a company is certified with ISO/IEC 27001

Answer:

There is 2 ways: 1.- Ask the company to show the certificate, 2.-Each certification body has this information (ISO 27001 certificate for each company). So, you need to know the certification body that issued the certificate for the company that you want, and you can to request information about a specific company. Most of the certification bodies have a web form in their website to search this information, but if not, you can directly ask to them.
