Symantec Endpoint Protection 14.3 RU6 represents a pivotal release in Broadcom’s endpoint security product line. The transition to 64-bit only support is the most significant system requirement change, eliminating 32-bit Windows support entirely. Organizations with remaining 32-bit endpoints must maintain SEP 14.3 RU5 or earlier clients, or plan hardware/OS upgrades.

SEP 14.3 RU6 supports 64-bit versions of the following major enterprise Linux distributions: 7.x, 8.x, 9.x CentOS: 7.x, 8.x Ubuntu: 18.04 LTS, 20.04 LTS, 22.04 LTS SUSE Linux Enterprise Server (SLES): 12, 15 Oracle Linux (RHCK and UEK versions): 7.x, 8.x, 9.x Memory (RAM) : 2 GB minimum; 8 GB

These requirements are based on NTFS file systems, with additional space required for content updates and logs.

Before diving into the hardware tables, note a critical change introduced in Release Update 6 (RU6):

Default port for standard client-to-management server communication.
