Deep Web
Web content not indexed by public search engines — paywalled articles, private dashboards, unlinked pages. Much larger than the dark web and mostly mundane.
Login portals and internal wikis are deep web. They are not hidden by Tor; they are simply not crawled. Conflating deep and dark web is a common media error.
