iOS 12 feature list (proposed)
- In transit/at rest encryption on all iCloud data.
- Private keys stay on iDevice, and must be manually moved/keyed.
- VPN Toolbox is native to iOS (no VPN apps required.)
- Real application based firewall to limit code/data infiltration/exfiltration (e.g. give state apps NO PERMISSIONS to execute.)
(Let me know if I have missed any others. 
)
