What happens when organizations fail to implement cybersecurity recommendations after a breach?

As illustrated by Lee Kim's client example, organizations that experience a breach but fail to improve their cybersecurity measures often face repeated attacks. This particular client suffered a second breach just two weeks after the initial incident because they neglected to conduct a postmortem analysis, implement tabletop exercises to test defenses, or deploy necessary security tools. In healthcare especially, the stakes are exceptionally high since compromised patient data, unlike financial information, cannot be replaced or restored once exposed. Breached healthcare data, particularly sensitive information like genomic sequences, remains permanently vulnerable once compromised.
