Book an informal conversation

ISO Ready helps you align policy, risk, and evidence, without endless document churn.

Run the ISO 27001 readiness scan

GDPR, ISO 27001 and 27701

Privacy controls for SaaS companies places privacy governance beside security. GDPR is legislation. ISO/IEC 27701:2025 is an independent privacy information management system (PIMS) standard that can be used alongside ISO 27001. A PIMS does not replace applicable legal obligations. Combine DPAs, processing records, DPIAs and security controls in one narrative.

Processing register and DPIA

Your processing record must match subprocessors in the vendor register. DPIA outcomes belong in the risk register with owners, not a side folder.

SaaS and privacy by design

For SaaS: document data flows, retention and subject rights per feature. Privacy by design means provable decisions in design and release, not only a policy.

Common mistakes

DPO without mandate; stale register; one-off DPIA; privacy and security use different language; no proof of rights handling.

Checklist

  • Sync register with vendors
  • Link DPIA to risks
  • Retention per data type
  • Subject rights process
  • Clarify privacy vs security roles
