Which word describes due care, which is intentionally open-ended and focuses on what is "reasonable and expected" under different circumstances?

The term that encapsulates the idea of due care in a way that emphasizes what is "reasonable and expected" under varying circumstances is best described as "prudent." This term implies a level of caution, wisdom, and decision-making that aligns with what a reasonable person would do in similar situations. In cybersecurity and risk management contexts, being prudent involves making thoughtful decisions about how to protect information and systems, weighing the potential risks, and implementing measures that are not only compliant but also sensible based on the circumstances.

"Reasonable" also touches on similar concepts, but "prudent" captures a deeper nuance of applying wise judgment to prevent harm or loss, aligning closely with the ethical obligations professionals hold in safeguarding assets or information. This focus on intentionality in risk management practices supports the idea that due care is not merely about compliance with standards, but about acting thoughtfully and purposefully in the protection of assets.
