The Siem Maturity Framework Workbook (V1.0): A Practical Scoring Tool For Security Analytics Platforms
Security Boulevard, Wednesday, February 11th, 2026
Over the last few weeks I published a post on the architectural and operational gaps that created the new wave of SIEM and AI SOC vendors. A bunch of people asked the same follow-up question: 'Ok, but how do I evaluate vendors consistently without falling back into feature checklists and marketing claims?'
So I turned the framework into a practical scoring workbook you can use to rate a platform across the dimensions I described in the post. The workbook allows you to rate each category from 1 to 5 and I spent some time defining what a 1 versus a 5 means in each of the categories. I give you an example for the 'Data Pipeline Optimization' category.
