# Screen lock should be enabled on devices

> Checks that screen lock is enabled on all devices managed by Microsoft Defender.

Checks that screen lock is enabled on all devices managed by Microsoft Defender.

## About

When you connect Microsoft Defender for Endpoint to DSALTA, the platform collects device posture using read-only API access. DSALTA activates this check for any device that does not meet the requirement.

## Why This Matters

Laptops and phones that are unencrypted, unlocked, or running outdated software are easy targets if lost or stolen. Enforcing endpoint baselines protects company data on every device and is required by SOC 2 and ISO 27001.

## How to Fix

**Before you begin**

* Ensure you have access to your MDM (Microsoft Intune) or device management console.

**Enforce screen lock on all devices**

1. Open **Microsoft Intune admin center** (or your Defender / MDM portal).
2. Create or edit a **compliance** or **configuration** policy for each platform (Windows, macOS).
3. Configure the policy to require a passcode and set the inactivity lock to 15 minutes or less.
4. Assign the policy to all device groups and set non-compliant devices to be flagged.

Once all managed devices comply, DSALTA retrieves the change on the next sync and sets the check status to **Passing**.
