Virtual Trust Zones (Primer)

A lightweight orientation on identity & context-based segmentation using VTZ claims.

Core Ideas

• Zones are cryptographically asserted, not inferred from IP space.
• Policy attaches to trust spans and travels with sessions.
• Decay of trust evidence shrinks zone privileges.

Example Policy Snippet

zone "prod-app" {
  require claims { device.attested, user.mfa, build.sha, binary.fingerprint }
  allow outbound.service == "payments" if reflex.score > 70
  deny outbound.* if data.classification == "restricted" && !session.ephemeral
}
