Encryption of Data at Rest: The Cybersecurity Last Line of Defense

In the ever-evolving landscape of cybersecurity, where threats are becoming increasingly sophisticated
and pervasive, traditional defenses alone are no longer sufficient to protect sensitive data. Despite the
implementation of comprehensive security measures such as Zero Trust architectures and Defense in
Depth strategies, organizations continue to experience significant security breaches. A critical
vulnerability that remains is the exfiltration of data by cybercriminals. Unlike the ransomware attacks of
the past that focused primarily on data encryption to demand ransom, modern adversaries now exfiltrate
data, posing severe privacy and regulatory risks. In this context, encryption of data at rest emerges as
the last and indispensable line of defense, rendering stolen data useless to attackers.
