I began by auditing our existing infrastructure to identify all devices that needed encryption and ensuring they met the necessary hardware requirements.

After that, I configured Group Policy settings to manage BitLocker deployment and recovery keys centrally. I coordinated with our help desk team to prepare them for the rollout and created detailed documentation and training materials to assist end-users. During the implementation, I monitored the progress closely and handled any issues that arose, such as TPM compatibility and user compliance. The result was a smooth transition with minimal disruption, and we significantly improved our data security posture.”
