Addressing issues that caused high CPU or memory usage in previous versions, resulting in a lighter footprint on end-user machines.
Always verify the actual SEP client version via GUI/registry. If the real version is 14.3.x or later, mark this finding as a false positive in your scanner. If the real version is 12.1.x, immediately plan an upgrade to SEP 14.3.x or migrate to Symantec Endpoint Security (cloud).
Released as part of the cycle by Broadcom, build 14.3.12154.10000 serves as a core stable release for the Symantec Endpoint Protection Windows Client . It integrates local signature-based scanning with cloud-delivered machine learning. This combination minimizes client-side footprint while maximizing zero-day threat detection.
