CASS from Start to Finish
Applicability, mapping, controls, risks and evidence.
All in one place.
✴
Reduce ambiguity
CASS rules are broken into clear, structured components so the obligations are easier to understand and apply consistently.
✴
Connect the whole process
Rules link naturally to controls, evidence, risks, and breaches — creating a coherent end-to-end view of how obligations translate into real operational activity.
✴
Strengthen oversight
Responsibilities, monitoring expectations, and assurance needs are aligned in a way that supports the kind of thinking a CF holder actually needs to evidence.
What I am building
A personal project exploring what a purpose-built CASS compliance tool could look like — starting with rule mapping and building outward from there.
Most firms manage CASS in spreadsheets. I wanted to see if there was a better way. This is what I’ve built so far.
