I want to become ISO 27001 certified but I'm not sure which certification to specialize in. I am currently working with a company creating policies with ISO 27001:2013 requirements. Since I am gaining extraordinary experience I would like to get your advice on which certification I should specialize in, either, Lead Auditor, ISMS, etc.
The best pathway will depend on your professional objectives. If you plan to work on an Information Security Management System certification process, then you should consider the Lead Implementer certification. If you plan to ensure the operation of an ISMS, then you should consider the Lead Auditor certification. Considering your current work, Lead Implementer certification seems more appropriated.
