Each row is taken live from that tool's profile, so a correction there shows here at once. The training column quotes the profile's own opening line word for word; the full section, with the plan-by-plan detail and the vendor documents it rests on, is on the profile. Ratings are our opinion, on the scale explained in our methodology. On the current 1 to 5 risk rating, 1 is the lowest risk. Vendors change their terms, so check the date and the vendor's current documents before you rely on a row. General information, not legal advice.
