At NexSec Global, EFS wasn’t just a convenience. It was policy. Every file on every employee laptop, every server share flagged as “Restricted,” was encrypted with a unique File Encryption Key (FEK), which itself was wrapped by public keys from authorized users—and crucially, by the DRA’s certificate. The DRA sat in a hardware security module (HSM) under two-person control. Or it should have.

The DRA serves as a critical recovery mechanism. If a user loses their EFS private key or leaves the company, their encrypted files become inaccessible. A DRA provides a backdoor that a system administrator can use to recover that data. The DRA uses a , which contains the necessary encryption keys to unlock EFS-encrypted files. Action: Use certmgr
