Ransomware, destructive malware, insider threats, and supply\u2011chain compromises have made data recovery a board\u2011level risk with direct financial, legal, and reputational consequences. A \u201cperfect\u201d cyber\u2011resilient architecture does not mean eliminating all risk; it means designing systems that <strong>assume compromise<\/strong>, limit blast radius, preserve recoverability, and restore critical operations with confidence.
