How to use this comparison
Support status
Supported, conditional, unknown and not-supported states are kept distinct so missing evidence is not treated as a negative fact.
Confidence
Confidence reflects the strength of the recorded evidence for this capability, not overall product quality.
Fit for your company
A product can strongly support this capability and still be a poor overall fit due to deployment, integrations, security, region, budget or other must-haves.
