Compliance Readiness Checklist

Prepare engineering evidence before the audit or enterprise customer review

Compliance readiness is an engineering practice: controls must exist, operate consistently, and produce evidence. This guide helps teams prepare for customer security questionnaires, SOC 2 readiness, ISO 27001 planning, GDPR reviews, or internal governance.

Readiness maturity#

LevelDescriptionCommon gap
0. UnmappedControls exist informally but are not tied to requirementsNobody knows where evidence lives
1. DocumentedPolicies and owners are namedControls are not tested or consistently followed
2. OperatedRecurring access, backup, vulnerability, and incident activities happenEvidence is manual and late
3. Evidence-readyEvidence is collected as part of normal operationsExceptions and risks need better governance
4. Continuous assuranceControl status is monitored with dashboards and automated exportsScope changes need strong change management

Core control areas#

AreaWhat to proveEvidence examples
Asset and owner inventoryProduction systems and data stores have ownersService catalog, repository owners, cloud account inventory
Access controlAccess is approved, least-privilege, and reviewedSSO policy, access review tickets, privileged access logs
Change managementProduction changes are reviewed and traceablePull requests, deployment records, emergency change log
Vulnerability managementFindings are triaged and remediated by severityScanner results, SLAs, remediation tickets, exceptions
Incident responseIncidents are classified, handled, and reviewedIncident timeline, communications, RCA, corrective actions
Backup and recoveryCritical data can be restoredBackup jobs, restore test evidence, retention settings
Vendor managementThird-party risk is understoodVendor list, DPAs, security reviews, subprocessors
Data protectionSensitive data is classified and protectedData map, retention policy, encryption configuration
Logging and monitoringSecurity-relevant events are visibleCloud audit logs, SIEM queries, alert routing
Training and awarenessStaff understand secure handling expectationsTraining roster, onboarding checklist, annual refresh records

30-day readiness checklist#

  • Define in-scope products, environments, cloud accounts, repositories, and data stores.
  • Identify control owners and evidence owners.
  • Create a single evidence folder or GRC workspace with dated evidence.
  • Export user and admin access lists from source control, cloud, CI/CD, databases, and production apps.
  • Record the latest backup restore test or schedule one immediately.
  • List all known critical/high vulnerabilities and their remediation or exception status.
  • Gather deployment history for a representative production release.
  • Document the incident response process and most recent tabletop exercise.
  • Build a vendor list with data access, contract owner, and review status.
  • Confirm that security training is assigned to new joiners and refreshed annually.

Customer security review preparation#

Prepare concise, evidence-backed answers for:

  • How production access is approved, reviewed, and revoked.
  • How customer data is encrypted, backed up, retained, and deleted.
  • How vulnerabilities are detected and remediated.
  • How incidents are communicated to affected customers.
  • How cloud infrastructure is isolated and monitored.
  • How vendors and subprocessors are assessed.
  • How staff are trained on secure data handling.

Control mapping examples#

Requirement familyEngineering evidence to collect
SOC 2 SecurityAccess reviews, vulnerability remediation, change approvals, incident records
ISO/IEC 27001Risk assessment, Statement of Applicability inputs, control owner map, internal review records
GDPRData processing map, retention/deletion procedures, DPA/subprocessor list, breach notification process
Customer questionnaireArchitecture diagram, encryption summary, availability posture, security contact, compliance roadmap

Research-backed anchors#

  • AICPA SOC 2 defines trust services criteria commonly requested by enterprise buyers.
  • ISO/IEC 27001 provides an information security management system framework.
  • The European Data Protection Board publishes GDPR guidance and supervisory authority materials.
  • NIST SP 800-53 is a detailed control catalog useful for mapping technical safeguards to control language.
