Hi Irakli,
Azure is an IASS (infrastructure as a service).
It also offers SAAS (software as a service) and PASS (platform as a service)
As such they're responsible for the patching and vulnerability assessments for those services.
They are not likely to offer up vulnerability assessment reports for these services.
You can read more about their shared responsibility policies here:
