Nothing dangerous gets in. Everything that crosses is proven.
A curated scenario: untrusted files arrive, Janus takes them in without ever running them, cleans what goes onward, seals the untouched original, and records every decision provably. (Preview is read-only — no uploads.)
Janus removes dangerous content from the copy passed downstream and seals the original untouched — it does not claim a stored file is harmless. Detection of intent is done by the security tools you pair it with. Sealed, monitored appliance. No upload, no telemetry.
