Our Endpoint Engineering and Security team is responsible for the end to end management of T-Mobile\'s client platform. We manage a traditional domain joined PC environment and are working towards a zero trust model currently. We work with partners across the organization to design and implement solutions that not only meet requirements but \"WOW\" our end users time and time again. We manage the System Center Configuration Manager(SCCM), Microsoft Intune, and Microsoft Endpoint Configuration Manager (MECM) platform. Our team also manages the relationship with a number of hardware vendors. Recently, our team migrated from a 21 day patch cycle to a 9 day patch cycle to comply with strict patching SLAs. Worked with team members to developed a software intake process that currently provides over 500 applications to our end users. Eliminated local administrators across the endpoint platform.Our team developed a pipeline that allows T-Mobile to quickly address these vulnerabilities and measure those results. Remediated critical vulnerabilities. Reached 0 critical vulnerabilities within 9 months of project start. Remediated over 4 million vulnerabilities since inception. Reduced average age at close from 30+ days to less than 9.One of the greatest risks in the enterprise is the running of unauthorized and potentially dangerous software. Our teams implemented an Application Control process across the client platform. Blocked unauthorized remote access tools across the enterprise Implemented a block by default policy that ensures only authorized software is allowed to run. Worked with the vendor to significantly improve the product to meet T-Mobile needs.
