Which labels should be used for information too valuable to allow any risk of its capture?

The choice of "Critical, Top Secret" is appropriate for information that is deemed too valuable to risk its capture.

The label "Top Secret" indicates a very high level of sensitivity regarding the information, suggesting that unauthorized disclosure could cause exceptionally grave damage to national security or organizational integrity. Such information is often subject to the most stringent safeguards and access controls.

The label "Critical" further emphasizes the importance of the information, indicating that it is essential to the functioning, security, or mission of an organization. This label signals that the information requires heightened protection measures to prevent any potential compromises.

Together, these labels convey a robust intent to protect the information rigorously, aligning with principles of information security that prioritize safeguarding highly sensitive and valuable data against any threats of exposure or capture.
