Certifications differences

Answer: The ISO 27001 Internal Auditor course prepares people to audit an ISMS against ISO 27001 so they can perform audits for their organizations, while the ISO 27001 Lead Auditor certification recognizes people who have competency on auditing an ISMS against ISO 27001 requirements and qualifies them to start the process to become a certification auditor.

Both contents for ISO internal auditor and ISO lead auditor can be useful to prepare someone for the CISA and CISSP certification exams, but otherwise they have no relation.
