Use the Overlap Tool by selecting one framework in Class A and another in Class B. Review the numbers, Venn diagram, and Jaccard similarity. Focus on the unique controls listed in the left and right boxes — those are your gaps. Check shared controls in the middle and the "Closest frameworks" section at the bottom. After you run a comparison, use Open in Domain Heatmap under Book a Demo in the header to visualize domain coverage for the same pair.
