A.3.22·high·Component: Security considerationsWhat this control requires
Protect PII on or accessible via user endpoint devices. Implementation: Endpoint controls, MDM, encryption and policies. Justification: Mobile and endpoints are high-risk vectors for PII compromise.
In plain English
Protect PII on or accessible via user endpoint devices. In practice, this means you can prove you implement user endpoint devices-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.3.22) and look for objective evidence on the latest two assessment cycles.
How to implement
Endpoint Protection
MDM. Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token.
EDR. Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h.
Operational checklist
- Implement. Document the trigger, the owner and the cadence.
- Encrypt. Document the trigger, the owner and the cadence.
- Protect. Document the trigger, the owner and the cadence.
- Scope: user endpoint devices.
Evidence to collect
- User Device Scan. MDM compliance state per user device (Intune / Jamf / Workspace ONE).
- Policy Document. A signed and version-controlled policy / standard / procedure document.
Signed policies, procedures, and registers document the safeguard. Endpoint/MDM telemetry proves device-side controls. Focus: User endpoint devices.
Common pitfalls
- Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure.
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.
