Fragmentation in cybersecurity refers to the existence of many different versions of software or operating systems, such as Android, across devices. This variation makes it challenging to deliver updates, security patches, and consistent user experiences. Because each version may have unique features or vulnerabilities, fragmentation can slow down the rollout of critical security fixes, leaving some devices exposed to threats for longer periods. It also complicates the work of developers and security professionals, who must account for a wide range of versions and configurations.
