CIS · Control 3.6 · Priority: critical · Component: Protect

### What this control covers

Encrypt data on end-user devices containing sensitive data. Example implementations can include: Windows BitLocker®, Apple FileVault®, Linux® dm-crypt.

### Why it matters

Endpoint posture (encryption, EDR, OS patch state) is also the most common evidence customers ask for in their vendor reviews.

### How to implement

#### AWS

Bake hardening into **EC2 Image Builder** + **AMI accounts**; use **Systems Manager Fleet Manager** for inventory and patch state.

#### Azure

**Intune** enrolment for laptops + phones; Conditional Access requires "compliant device" before any corporate app loads. EDR via **Defender for Endpoint**.

#### Google Workspace

**Endpoint Management** (basic/advanced) for BYOD/COPE; require screen lock, disk encryption and OS minimum; block sign-in on jailbroken devices.

### Evidence to collect

-   `user_device_scan` — Output from your MDM/EDR (Intune, Jamf, Kandji) showing managed-device count, posture and last-check-in.

Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: Encrypt Data on End-User Devices.

### Quick checklist

-   Encrypt — End User / Sensitive
-   Protect — End User / Sensitive
