SkieWhat is policy reach in Insights?
Policy reach shows how widely each policy applies: how many groups and devices sit under it. It helps you see the effect of a change before you make it, and spot policies that cover nothing or cover far more than you meant. Pair it with the impact preview before editing.
Skie keeps a policy library and app lists, and each group has one policy and one app list. Rules flow down the structure, and the most specific level applies last. After a few months, an organisation can end up with a lot of policies, and the question becomes: who is actually under which?
Policy reach answers that. For each policy it shows the groups and devices under it. That makes two common problems easy to see. One is an old policy no group uses any more, which can be tidied away. The other is a policy used by far more devices than you remembered, so editing it would change a lot at once.
That second point is why it sits next to the impact preview. Before you change anything, the preview tells you exactly which groups and devices a change will touch. Reach tells you the standing picture; the preview tells you the effect of this particular edit. See impact preview before a change. The where-used view and the effective policy view give more detail on a single device.
Remember that blocking beats allowing. A group can carry an app list that allows something while a higher level blocks it, and the block wins. Reach tells you how many devices are in that situation; the effective policy view tells you why.
Practical tip: review reach each term. A short look at which policies cover which groups prevents the slow build-up of near-duplicate policies that nobody dares touch. If you need to fork one, do it deliberately.
