The ARM64 experience depends entirely on your operating system. Broadcom handles Windows and macOS with radically different strategies.
Early versions (14.3 RU1-RU7) ran under Microsoft’s x64 emulation on ARM. This caused delayed real-time scanning and a 15-20% performance hit—hence the "hot" (overworked CPU) complaints. RU8 fixed this natively.
To understand the panic, you have to understand the "hot" part of the story. For nearly two decades, Symantec Endpoint Protection (now owned by Broadcom) was the gold standard for hybrid x86/x64 environments. Its driver—the SysPlant.sys —dug deep into the Windows kernel to monitor file system activity, block ransomware, and enforce firewall rules. symantec endpoint protection arm64 hot

With the surge in adoption of Qualcomm Snapdragon and Microsoft Surface Pro X devices, the demand for security solutions that run natively on ARM64 architecture has become a "hot" topic. Broadcom (the parent company of Symantec) has adjusted its roadmap to accommodate this.
