Symantec supports Apple's ARM-based chips (M1, M2, M3, M4) starting with these versions: Apple M1: Support added in 14.3 RU2. Apple M2: Support added in 14.3 RU5. Apple M3 series: Support added in 14.3 RU8. Linux ARM Support

Historically, ARM architecture for Linux agents was listed as under development on the roadmap. You should verify the latest documentation on the Broadcom Tech Docs portal for any updates regarding native Linux ARM64 support in more recent RU (Release Update) versions. Hotfixes and Updates

Security definitions and engine updates for ARM64 clients are typically delivered via LiveUpdate, similar to standard x64 clients. To obtain the proper installation package for ARM64, users should download the Full Installation package from the Broadcom Support portal and select the Windows ARM architecture option.

Are you looking to deploy this to Windows 11 ARM devices or a specific Linux distribution?

1. The Rosetta 2 Tax (macOS only)

Rosetta translates x64 instructions to ARM64 on the fly. SEP’s real-time scanner (ccSvcHst.exe on Windows, SymantecDaemon on macOS) creates thousands of translation lookups per second. Each translation generates heat. The fix? Replace SEP on macOS with a native ARM64 competitor (e.g., Microsoft Defender for Endpoint or SentinelOne).

3) Pre-deployment evaluation (lab first)

  1. Inventory: list device models, OS builds, and architecture (ARM64 vs x86_64).
  2. Vendor support check: confirm SEP ARM64 builds and supported OS releases from Broadcom/Symantec release notes.
  3. Create a test lab: representative devices—one per major OEM/OS build.
  4. Baseline tests:
    • Installer run and service status
    • Boot persistence (survives reboot)
    • On-access scanning: create/modify malicious-test files (EICAR)
    • Network protections: access known-malicious hosts (in controlled environment)
    • Performance: CPU, memory, I/O, boot time impact
    • App compatibility: common enterprise apps, kernel updates
  5. Rollback plan: snapshot or recovery image ready before install.

Issue 2: Performance Lag

  • Cause: If SEP is running, but the system is slow, you might be running a 32-bit (x86) version under emulation.
  • Solution:
    1. Open SEP client.
    2. Click Help > Troubleshooting.
    3. Check the "File Version". If it does not mention ARM64, or if you see high CPU usage from ccSvcHst.exe, uninstall and seek the specific ARM64 native build.

"My Windows ARM64 laptop still runs hot after installing the native client."

Fix: Check for conflicting security products. Windows Defender may still be active. Disable Defender via Group Policy (Admin Templates > Windows Components > Microsoft Defender Antivirus > Turn off Defender). Then, run C:\Program Files\Symantec\Symantec Endpoint Protection\14.3\Bin\ccSvcHst.exe and set CPU affinity to use only high-efficiency cores (via PowerShell).

b) Hotfix (Quick Patch)

Broadcom occasionally releases hotfixes for ARM64 SEP, e.g.:

  • Hotfix 3532972 – resolves kernel panic on ARM64 with specific network drivers
  • Hotfix 3590018 – fixes memory leak in real-time scan on ARM64
