AI-native score

How ready this product is for agents to use, on a 0–100 scale across four weighted dimensions. Security is one of them, so a high score is not a substitute for your own security or vendor-risk review. How is this scored?

Unrated. Only 4% of the scored decision fields are researched, so the grade is held until more are confirmed. The breakdown below shows what's been scored.
