As mobile apps and social media platforms rapidly evolve, eDiscovery teams must navigate complex challenges in preservation, collection, processing, review, and production while balancing privacy concerns and legal defensibility. From ensuring full data capture—including cloud-synced content and ephemeral messaging—to dealing with partial exports from apps like Discord and Signal, defensibility is key. This panel will discuss best practices for identifying what to collect, addressing privacy implications, disabling auto-deletion, authenticating social media evidence, and developing effective workflows for review and production. With courts increasingly scrutinizing mobile and social media discovery, this session will provide practical strategies for staying ahead in this dynamic digital landscape.
