With iOS 26.1 beta 1, which was released to beta testers on Monday, the company is rebuilding how Rapid Security Responses work. But there’s a key difference between Rapid Security Responses and the new Background Security Improvements: The new Background Security Improvements will be installed silently on the device without needing to manually update. Previously, users had to download Rapid Security Responses through the Settings app just like any other iOS update. With Rapid Security Responses, Apple says a restart may be required “if necessary.”Apple will also have the ability to roll back a Background Security Improvement if there are any issues. iOS code suggests that the new Background Security Improvements are also coming to other Apple platforms, including macOS.
