Symantec Endpoint: Protection 14.3 Ru6 System Requirements

The client software runs on endpoints (workstations, servers, VDI). Below are the supported OS versions and hardware minimums per client.

SEP 14.3 RU6 runs natively on the following hypervisors and cloud instances, provided the guest OS meets above requirements.

| Platform | Supported Versions | Notes | |----------|--------------------|-------| | VMware ESXi | 6.7, 7.0, 8.0 | Use VMXNET3 network adapter; enable hardware virtualization | | Microsoft Hyper-V | Windows Server 2016/2019/2022, Windows 10/11 Pro/Enterprise | Dynamic memory recommended to be disabled for SEP | | Citrix Hypervisor | 8.2 LTSR, 8.2 CU1+ | – | | Nutanix AHV | AOS 5.20+ | – | | AWS EC2 | Any instance type (t3, m5, c5 families) | Use dedicated EBS-optimized volumes | | Microsoft Azure | Dv3, Ev3, or higher series | – | | Google Cloud (GCE) | N2, C2, or E2 series | – |

Virtualization-Specific Considerations:

Apple’s tightened security policies (System Extensions, Notarization) mean that SEP 14.3 RU6 requires macOS 11 (Big Sur) or later.

| Pros | Cons / Gotchas | |-------|----------------| | Supports modern Windows Server versions | No Windows Server 2012 R2 (forces upgrade) | | Embedded DB improved, but still slow past 500 nodes | Linux client lacks full firewall (only basic) | | Smaller memory footprint than 14.2 | ARM64 Windows not supported (x86 emulation only) | | HTML5 console works on any modern browser | No official support for Windows 10 LTSC 2015/2016? (2019 LTSC OK) |

| Current Version | Direct to RU6? | Action | |---------------------|-------------------|-------------| | 14.3 RU1–RU5 | Yes | Use SEPM upgrade wizard | | 14.2 or older | No | Upgrade to 14.3 RU5 first | | 12.1.x | No | Fresh install + migrate policies | symantec endpoint protection 14.3 ru6 system requirements
