Google Research

David Challoner


These days I primarily lead the team which runs the systems that implement different kinds of data access controls across Google. These are used by external products like Assured Workloads, Access Transparency, or Customer Approvals. I also work on furthering Google's adoption of its own cloud technologies in my work with our Enterprise Cloud Solutions (ECS) workgroup specifically focusing on networking and Google's internal adoption of Anthos Service Mesh (ASM).

Previously I've worked on services that power our Endpoint Verification and Context Aware Access pipelines which are used both internally at Google and by Cloud Customers to implement Zero Trust (or Beyond Corp) IT security and before that, internal storage (nfs/smb, distributed software defined storage)
