• Demonstrates the need for continuous evidence of patch deployment for audit readiness.
• Supports mapping of software‑update controls across multiple compliance frameworks.

Who is affected

Recommended actions

1. Inventory all Siemens Desigo CC and Gridscale instances and verify version numbers.
