Audit trail
Also called audit log, activity log
Definition
An audit trail is the log a virtual data room keeps of every action: who logged in, which documents they opened, for how long, and what they downloaded or printed. Sellers use it to see which bidders are serious, and it is evidence of what a buyer was shown if there is a dispute after the deal.
