| Component | Requirement | Review / Notes | |-----------|-------------|----------------| | | Windows Server 2016, 2019, 2022 (Standard/Datacenter) Windows Server Core supported (limited UI) | No Windows Server 2012/R2 (EOL). No Linux for SEPM itself. | | RAM | 8 GB minimum (16+ GB recommended for > 1,000 clients) | Under 8 GB leads to slow console response and DB issues. | | CPU | 4+ cores (2.5 GHz+) | Database operations (embedded or remote SQL) are CPU-heavy. | | Disk | 50 GB minimum (100+ GB recommended) | For logs, content updates, and database growth. Use SSD. | | Database | Embedded (Simplified) or SQL 2017/2019/2022 | Embedded suitable only for < 500 clients. For production, always use external SQL. | | Browser | Chrome, Edge, Firefox (modern) | IE mode no longer required. | | .NET | .NET Framework 4.8 | Required for console & services. |

Running SEP 14.3 RU6 in virtualized environments requires special attention to resource overcommitment.

In addition to the operating system and hardware requirements, SEP 14.3 RU6 has several other system requirements:

Requires at least 40 GB, with 200 GB recommended for log retention.

At least 100 GB of free space is necessary for the application and the local database metadata.

Before deploying SEP 14.3 RU6, organizations should complete the following checks:

Full support for modern Windows 10 versions is included.

For 64-bit environments, SEP 14.3 RU6 delivers enhanced ransomware protection, improved Linux client flexibility, and better management visibility. Careful planning around system requirements, particularly processor architecture validation and disk space allocation, ensures successful deployment.

Minimum of 16 GB available space (100 GB recommended).

| 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) |

The Symantec Endpoint Protection Manager remains a critical component for on-premises deployments. SEP 14.3 RU6 SEPM supports managing 32-bit clients only at the RU5 level or earlier; 32-bit computers cannot run the RU6 client.

The Windows client software runs locally on workstations and servers to provide real-time proactive threat protection. Hardware Specifications

. If you are managing 32-bit machines, they must remain on version 14.3 RU5. Broadcom TechDocs Symantec Endpoint Protection Manager (SEPM)
