Why do you need a lead assessor / lead auditor during the SOC2 or ISO27001 certification process?

 

TLDR

Businesses typically ask us why a Lead Assessor is needed for a SOC2 or ISO27001 certification / audit. We say a Lead Assessor (or Lead Auditor) plays a critical role in the SOC 2 or ISO 27001 certification process because they ensure that the company meets the required security, compliance, and risk management standards. Their expertise helps companies avoid costly mistakes, streamline the audit, and ultimately achieve certification. Do not confuse them with external auditors (e.g. CPA’s for SOC2) who certify the process. Lead Assessors / Auditors in this case are either inhouse or third party consultants like Frigg Business Solutions who speed up the certification process. A good consultant not only shares tried & tested tips, but also reduces errors & rework by getting the job done correctly the first time.
