Implied technologies
Detecting PencilBlue implies these are in the stack too - a report lists them alongside it.
How we audit PencilBlue
We measure the detected version against PencilBlue's release history and grade the surrounding stack with a Lighthouse-grade quality audit. Weak or outdated links weigh more - one risky dependency can pull the whole score down.
