I am working with companies as a consultant and helping them prepare policies they require for ISO27001 and ISAE3402 (also SOC1 and SOC2). I have also managed the audit process for my own business.
My question is what can I do if I get certified that I can't do now? Secondly, do I have to get certified for all 4 - ISAE3402/ISO27001/SOC1/SOC2 or can I do one overarching certification that will apply to all? Also what are the global bodies that accredit ISO certifications and does that apply to Advisera?
Thanks for your help.
