Apple reports that no Lockdown Mode users have experienced spyware attacks since the feature launched four years ago. The security opt-in protection disables device features commonly exploited by government spyware from companies like NSO Group and Intellexa, helping defend high-risk customers from targeted intrusions.

Independent researchers including Amnesty International and Citizen Lab confirm no successful iPhone compromises where Lockdown Mode was active. In documented cases, the feature actively blocked Pegasus and Predator spyware, causing some spyware to abandon attacks upon detecting its presence.

Apple security expert Patrick Wardle calls Lockdown Mode "one of the most aggressive consumer-facing hardening features ever shipped," as it eliminates common attack vectors and forces spyware makers to develop more complex techniques. The author recommends enabling this protection for anyone concerned about potential spyware targeting.
