90-Day Audit Readiness Checklist

The 90-Day Audit Readiness Checklist from ZenGRC provides a detailed, five-phase, week-by-week plan for preparing security or compliance audits like SOC 2, ISO 27001, HIPAA, PCI, or NIST by guiding teams through framework scoping, control ownership assignment, evidence mapping, gap remediation, and stakeholder briefing to ensure a smooth, organized, and confident audit experience.

Preparing for a security or compliance audit doesn’t have to be a scramble. Whether you’re working toward SOC 2, ISO 27001, HIPAA, PCI, NIST, or another framework, having a structured plan makes all the difference between a smooth audit and a stressful one. This checklist from ZenGRC breaks the process down into five clear phases over 90 days — from initial discovery and evidence collection through gap remediation, pre-audit review, and audit week itself.

Each phase gives your team concrete, actionable steps: identifying framework scope, assigning control owners, mapping evidence, closing technical gaps, and briefing stakeholders before auditors arrive. Whether you’re going through your first audit or tightening up an existing compliance program, this week-by-week guide helps you stay organized, avoid last-minute surprises, and walk into audit week with confidence.
