A notification preview is a snippet of message content displayed on a device’s lock screen or notification center before opening the app. In cybersecurity, notification previews can pose privacy and security risks, as sensitive information may be exposed to anyone with physical access to the device. Many operating systems allow users to customize or disable notification previews to protect confidential data. Organizations often recommend disabling or limiting previews for apps handling sensitive information, such as email or messaging platforms, to reduce the risk of data leakage or unauthorized access. Managing notification previews is a simple yet effective step in securing personal and corporate devices.
