SOC 2 preparation usually happens in a few stages. First, your company should identify all “key systems” and perform a gap analysis against all requirements documented in the Trust Services Principles and Criteria. Next, existing security controls should be identified and policies and procedures should be written to meet all requirements. This can take anywhere from a few weeks to up to 6 months, depending on the size and maturity of your company. At this point you are ready for the SOC 1 Type I audit. A SOC 2 Type II audit is typically performed 6 months later.
