Me thinks that if you have a highly secure SAP landscape but no access to S-Account, then you are not authorized to implement the server side correction.
A customer basis admin will have access to the correction source and instructions in the SAP note. They will also know what the dependencies are and be able to judge the priority and testing requirements.
Subscription services to advisories without access to SAP notes and no understanding of SAP is not good for customers and system stability.
