Hi @Dennis Trabandt 

Thank you for your response. Regarding several approaches available for TLS certificate discovery, ServiceNow documents and Learning university has details about how to configure each method. I will also share detailed explanation about each method and differences shortly.

 

Secondly, we started with the goal of ensuring the certificates are renewed on time with automated reminder notifications to owners. unfortunately, with these challenges that I mentioned in my article and CMDB data dependencies, it was not achievable with 100% automation. So, we had to plan automation + manual approach. We are still in the process of realizing its value.
