Tails is a Debian-family Linux distribution based on Debian Stable. The Amnesic Incognito Live System — leaves zero trace on your computer and routes all traffic through Tor.
Strengths: Zero forensics footprint: shuts down by overwriting RAM; All connections routed through Tor or blocked completely; Preconfigured with KeePassXC, VeraCrypt, OnionShare, and Tor Browser. Trade-offs: Cannot be installed as a traditional permanent daily OS; No persistent apps or settings unless explicitly configured in encrypted storage.
