Lockdown Mode is a security feature introduced by Apple to provide enhanced protection for users who may be at risk of sophisticated cyberattacks, such as journalists, activists, or government officials. When enabled, Lockdown Mode restricts certain device functionalities, including message attachments, web technologies, and incoming communications, to minimize potential vulnerabilities. This mode is designed to defend against targeted spyware and exploits by significantly reducing the attack surface, while still allowing essential device operations.
