First generation encryption products such as Full Disk Encryption were designed long ago to protect primarily Windows-based endpoint devices. But data security has evolved beyond merely encrypting bits on disks. It is no longer the best approach due to lack of protection against insider threats and significant manageability and usability issues. Rather, companies need a solution with integrated architecture and a data-centric, policy-based encryption approach that can be consistently enforced wherever the data resides, across heterogeneous endpoint device types and end users. The paradigm must shift from Full Disk Encryption to Full Data Encryption. This white paper explains why companies today need a Full Data Encryption solution that simultaneously meets their security, IT operations, and compliance needs.
