Why ISO 27001 Matters for PII Protection
ISO 27001:2022 is the international standard for information security management systems (ISMS). While GDPR and HIPAA mandate what data to protect, ISO 27001 provides the framework for how to protect it systematically.
Annex A defines 14 control domains covering everything from access control and cryptography to incident management and compliance. Organizations seeking certification must demonstrate implementation of applicable controls through a Statement of Applicability (SoA).
This guide maps each Annex A domain to specific cloak.business features and infrastructure, showing how a PII protection platform can serve as a key component of your ISMS.
Annex A Control Domain Mapping
Information Security Policies
Management direction and support for information security in accordance with business requirements and relevant laws.
Organization of Information Security
Internal organization, roles, responsibilities, and management of mobile devices and teleworking.
Human Resource Security
Security aspects for employees joining, during employment, and when leaving the organization.
Asset Management
Identification of information assets and definition of appropriate protection responsibilities.
Access Control
Business requirements for access control, user access management, and system and application access control.
Cryptography
Cryptographic controls to protect the confidentiality, authenticity, and integrity of information.
Physical and Environmental Security
Prevention of unauthorized physical access, damage, and interference to facilities and equipment.
Operations Security
Operational procedures, protection from malware, backup, logging, and monitoring.
Communications Security
Network security management and information transfer security.
System Acquisition, Development, and Maintenance
Security requirements for information systems, secure development, and test data.
Supplier Relationships
Information security in supplier relationships and service delivery management.
Information Security Incident Management
Management of information security incidents, including reporting and response.
Business Continuity Management
Information security continuity and redundancies for availability.
Compliance
Compliance with legal and contractual requirements, and information security reviews.
Key Implementation Highlights
Cryptography (A.10)
Three encryption algorithms cover different use cases: AES-256-GCM for reversible PII encryption, XChaCha20-Poly1305 for local vault storage, and Argon2id for key derivation. All data encrypted at rest and in transit.
Access Control (A.9)
Mandatory 2FA with TOTP, zero-knowledge login option, and complete login audit logging. Every authentication attempt is recorded with IP, user agent, device type, and failure reason.
Asset Management (A.8)
~320 entity types across 70+ countries, each classified by sensitivity level and applicable regulations. The entity library serves as a comprehensive data asset inventory for PII.
Incident Management (A.16)
Login audit logging with suspicious IP detection, automated health monitoring every 5 minutes, and 90-day log retention with automated cleanup.
ISO 27001:2022 Updates
The 2022 revision restructured Annex A from 114 controls in 14 domains to 93 controls in 4 themes: Organizational, People, Physical, and Technological. The original domain concepts (A.5–A.18) were reorganized into this new structure, though the underlying security objectives carry forward.
New controls particularly relevant to PII protection include:
- A.5.7 Threat intelligence — Monitoring for new PII attack vectors and data breach patterns
- A.8.11 Data masking — Core functionality of cloak.business with 5 anonymization methods
- A.8.12 Data leakage prevention — Chrome extension and Office Add-in intercept PII before it leaves the organization
- A.8.24 Use of cryptography — AES-256-GCM, XChaCha20-Poly1305, and Argon2id implementations
Key Takeaways
- ISO 27001 provides the "how" — While GDPR says what to protect, ISO 27001 provides the systematic framework
- All 14 domains are addressed — From policies and access control to cryptography and compliance
- PII protection is central to ISMS — A dedicated PII tool covers data masking, encryption, access control, and audit logging
- German infrastructure supports compliance — ISO 27001-certified data center, EU data residency, no third-party data sharing
