Security that starts at zero and holds at one.
Zerone builds Zero Door: file integrity that checks legitimacy, not just change. Disk, access lists and memory, one verdict, evidence an auditor can verify.
A server produces thousands of changes a day. You should hear one voice.
Package updates, log rotation, temp files, a real implant: they all look like change. Zero Door asks a different question of each one: is it legitimate? Signed by whom, shipped in which package, seen where before, and does what runs in memory match what sits on disk. It speaks only when the answer is no.
