1. Employee reports device lost/stolen via Slack #it-help or PagerDuty.
2. IT admin verifies identity (video call or manager confirmation).
3. Immediately issue remote lock command (wipe only if data-sensitive).
4. Rotate any credentials cached on the device:
   - Revoke SSO sessions (Okta/Google Workspace admin console)
   - Rotate API keys stored on the device
   - Revoke VPN certificates
5. File a police report if theft is suspected.
6. Remove device from MDM after 30 days or once replacement is shipped.
7. Update asset inventory and notify finance for insurance claim.

# onboarding-checklist.yml — track in your ticketing system or Fleet
new_hire_onboarding:
  pre_day_one:
    - Purchase and ship device via CDW/Apple Business Manager
    - Assign device to MDM server in ABM/Autopilot
    - Create accounts: Google Workspace / M365, Okta SSO, GitHub, Slack
    - Generate VPN invite (Tailscale, WireGuard)
    - Prepare welcome documentation link

  day_one_automated:
    - Device powers on and auto-enrolls in MDM (zero-touch)
    - MDM pushes security profiles (encryption, firewall, password policy)
    - Software bundle installs automatically
    - User signs into SSO — all apps authenticate via SAML/OIDC
    - Compliance policies begin evaluation

  day_one_manual:
    - IT schedules 15-min welcome call to verify setup
    - Employee confirms disk encryption enabled (fdesetup status / manage-bde)
    - Employee joins #it-help Slack channel
    - Employee completes security awareness training link

  week_one_verification:
    - Fleet/MDM dashboard shows device as compliant
    - All critical policies passing (encryption, firewall, OS version)
    - VPN connectivity verified
    - MFA enrolled on all critical services
