Execute the controlled removal of legacy Trellix security agents following successful Defender implementation and validation and support decommissioning of the legacy Trellix/ePO environment. Configure and validate native disk encryption, including BitLocker for Windows and FileVault for macOS, and verify encryption status and recovery-key escrow before removing applicable legacy technologies. Troubleshoot endpoint-security and deployment issues, including agent conflicts, installation failures, connectivity problems, policy conflicts, and operating-system-specific configuration issues. Support macOS security requirements, including applicable system and security extensions, and Linux Defender deployment using shell scripting and Linux system-management tools. Maintain compliance with applicable DISA STIGs and DoD cybersecurity requirements across managed endpoints. Test and validate endpoint configurations and support phased deployment activities, including pilot groups, production migration, exception handling, and remediation. Track endpoint onboarding, migration, and remediation progress and provide status information supporting the master project schedule. Develop and maintain SOPs, deployment procedures, troubleshooting guides, configuration documentation, and operational playbooks. Coordinate with cybersecurity, infrastructure, service desk, and engineering personnel to resolve endpoint migration and operational issues.
