The retail industry has rapidly adopted Android edge devices for mission-critical use cases, but many struggle to scale security and compliance to these devices. Retailers face significant challenges in deploying and managing secure edge device fleets due to the high turnover rate of employees and remote branch locations. To mitigate human risk, retailers must implement secure configurations that restrict device usage, limit user access, and enforce acceptable use policies. Insecure networks are also a major factor in edge device security risks, and retailers must re-architect their branch networks into smaller segments to isolate mission-critical devices and sensitive data. Consistent early OS updates are crucial to prevent exploitation by financially-motivated threat actors, and retailers can adopt automation and DevOps approaches to scale security controls with limited resources.
