Free-ish version of Bitsight?

I'm at a not-for-profit. We, like many others, got dinged on CS insurance this year. They gave us a BitSight report that includes all of our public wifi users - wonderful. The do give us dashboard-only access which is a bait to "buy" because you can't drill down. Unfortunately we NAT public WiFi and other computers together... is there any other software I can use to do this kind of check on an IP block?
