NeatDrive

NeatDrive audits the Google Drive account of the person who connects it — it is not a domain-wide Workspace audit and needs no admin access. It finds files shared publicly or with people outside your organization, duplicates, and files sitting loose in your Drive root, and lists every one by name. It then stages the fixes for you to approve: revoke a link, rename, archive. Nothing in your Drive changes until you approve it. Scanning is free — four audits a month. The $19 audit gives you 30 days to fix what it finds; the $9 monthly plan covers ongoing audits after that. NeatDrive reads file names, sizes, dates and sharing settings, not the contents of your documents, except two opt-in features — content-aware naming, which reads roughly the first 2,000 characters of files you select, and a content-based duplicate check, which computes a checksum in memory and keeps only the hash. Google has verified the app and its Drive access, and it is independently security assessed under Google's CASA framework by an authorized lab, renewed annually.
