ISO/IEC 27701:2019
Without certified privacy controls, data-sharing agreements stall and regulatory exposure compounds across every jurisdiction you operate in.
ISO/IEC 27701:2019 is the world’s premier privacy extension to the ISO 27001 Information Security Management System, effectively establishing a Privacy Information Management System (PIMS).
For enterprises navigating complex global supply chains, paper-based privacy policies are obsolete. Regulators and enterprise clients demand verifiable evidence of data minimization, explicit consent tracking, and cross-border transfer restrictions.
StremarControl engineers and operates the Microsoft-native controls required for ISO 27701 mandates, translating privacy obligations into enforceable Microsoft Purview policies—structured retention schedules, data masking controls, and repeatable Subject Access Request (SAR) fulfilment workflows.
Why This Matters Now
As global privacy legislation fragments into hundreds of distinct jurisdictional mandates (GDPR, CCPA, PDPL), enterprise procurement requires a unified, verifiable standard. ISO 27701 extends ISO 27001 to mandate strict, deterministic privacy controls for PII controllers and processors. Without certification, firms face significant friction in B2B data-sharing agreements. StremarControl engineers an architecture where privacy is not merely a policy, but a enforced, auditable reality within your Microsoft 365 tenant.
Framework Metadata
Scope & Applicability
ISO 27701 applies to any organisation acting as a PII controller or PII processor. Because it is an extension of ISO 27001, an organisation must hold or concurrently achieve 27001 certification. In an M365 environment, the scope encompasses all data repositories—Exchange, SharePoint, OneDrive, Teams—where PII is stored, transmitted, or processed. Auditors scrutinise data mapping, consent tracking, and boundary enforcement.
Core Obligations
PII Identification & Mapping
Determine and document the lawful basis for PII processing. Maintain a inventory of PII flow across all internal and external boundaries.
Privacy by Design
Embed privacy controls directly into the architecture of IT systems. Enforce strict data minimisation and pseudonymisation protocols.
Cross-Border PII Transfers
Cryptographically enforce geographic boundaries on PII processing, ensuring data does not egress to unapproved jurisdictions.
Subject Access Rights
Deploy rigorous systems to rapidly identify, isolate, and export or delete PII upon a valid data subject request.
Microsoft 365 Control Mapping
How each obligation maps to enforceable Microsoft 365 controls and the evidence they produce.
PII Identification & Mapping
Purview Data Map & Exact Data Match (EDM) classifiers index all PII across SharePoint and Exchange. Automatic sensitivity labelling applied based on data classification signatures.
Data map telemetry, EDM match incident logs, auto-labelling precision reports.
Privacy by Design
Purview Information Barriers prevent PII cross-contamination between departmental boundaries. Default retention policies enforce strict, enforced deletion schedules.
Information Barrier configuration logs, disposition review artifacts, data age compliance reports.
Cross-Border PII Transfers
Purview Data Loss Prevention (DLP) and Azure Conditional Access geo-fencing restrict the egress of PII to unapproved international IP spaces.
Geographic DLP block telemetry, Conditional Access geo-denial logs, rigorous cross-border incident reports.
