iMessage attachments (most types). Web technologies (some JIT JavaScript). Link previews. FaceTime calls from unknown numbers. Wired connections to other devices. Profile installation. Apple services connection blocking. Reduces attack surface dramatically.Trade-offs to consider
Some websites won\'t work properly (require disabled JavaScript features). iMessage from new contacts limited. Sharing photos/videos limited. Some apps degrade. Generally usable but features reduced. Inconvenience for security.Per-app exceptions
Settings → Privacy & Security → Lockdown Mode → Configure Web Browsing. Exclude specific websites where Lockdown Mode breaks things. Granular control. Most users don\'t need exceptions but option exists.Combined with other protections
Lockdown Mode + Stolen Device Protection + Hardware Key on Apple Account + Faraday bag for sensitive meetings + Find My always on = comprehensive high-threat security. Each layer addresses different vector.State-sponsored threat reality
Pegasus, Predator, similar zero-click spyware target specific individuals. $1M+ exploits. Lockdown Mode breaks attack chains by disabling exploited features. Apple's documentation: Lockdown Mode designed to defeat state-sponsored mercenary spyware.When to enable + disable
Enable when entering hostile environment (foreign reporting trip, sensitive meeting). Disable when situation normal. Some always-on for journalists. Personal threat model determines posture. Most importantly: review threat model first.Mail-In Repair Service
