| Security warning | Choose security warning when the system has a security-risk signal and proceeding could expose credentials, personal data, payment data, device integrity, account access, or organization assets. | The warning appears before the risky navigation, submission, download open, file preview, install, or sensitive account action completes. | Supports blocked preview behavior for files downloaded from the internet. |
