**ISO/IEC 27701:2025**·Annex A `A.3.30`·high·Component: **Security considerations**

## What this control requires

> Direct, monitor and review outsourced PII processing system development. Implementation: Contractual requirements, monitoring, code reviews and acceptance tests. Justification: Ensures third-party development meets privacy/security requirements.

### In plain English

Direct, monitor and review outsourced PII processing system development. In practice, this means you can prove you implement outsourced development-level controls on a defined cadence.

## Why it matters

ISO 27701 is the international way to evidence the GDPR principle of accountability: certified PIMS controls translate directly into the records, contracts and rights-handling that supervisory authorities want, and into the privacy-engineering evidence SOC 2 + Privacy auditors and enterprise procurement teams ask for.

This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

## What an auditor looks for

PIMS auditors expect ISO 27001 to be implemented first and then the 27701-additional controls tested. For PII controllers they look at lawful-basis and rights-handling evidence; for PII processors they look at customer-instructions, sub-processor controls and return/transfer/disposal evidence.

Within **Security considerations**, the assessor will trace your implementation back to the catalogue reference (Annex A A.3.30) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Secure Development

**Pipeline.** Require code review, SAST (Semgrep / Snyk Code), SCA (Dependabot / Renovate), secret-scanning and IaC scanning in the merge pipeline.

**Branch protection.** Protected branches enforce reviews, signed commits and passing CI before merge; document the protection rules as the control evidence.

### Operational checklist

-   **Implement.** Document the trigger, the owner and the cadence.
-   **Ensure.** Document the trigger, the owner and the cadence.
-   **Monitor.** Document the trigger, the owner and the cadence.
-   **Scope:** outsourced development.

## Evidence to collect

-   **Vendor Risk Management.** `vendor_risk_management` evidence
-   **Policy Document.** A signed and version-controlled policy / standard / procedure document.

Signed policies, procedures, and registers document the safeguard. Processor due diligence, contracts, and disclosure registers evidence third-party controls. Focus: Outsourced development.

## Common pitfalls

-   CI security checks set to warn-only; the merge button is faster than the security feedback.

## How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
