Layers of the web
- Surface web: Indexed pages you can find with normal search engines.
- Deep web: Content behind logins (e.g., private dashboards, cloud storage).
- Dark web: A small part of the deep web that requires special software to access. It enables anonymity and is used for both privacy tools and, at times, illicit marketplaces.
Important: this site does not link to or access dark‑web sites. Examples shown are synthetic and for teaching only.
