No. As of 2025, Broadcom has released 14.3 RU8 and is moving toward SEP 16. RU5 is stable but lacks newer features like enhanced EDR and full Win11 23H2 support.

Important Note: Symantec Endpoint Protection is enterprise-grade commercial software. It is not available as a free public download. You cannot legally download the full installer or license keys from third-party "shareware" or file-hosting sites (such as Getintopc, FileCR, or Softpedia) without violating Broadcom’s terms of service and potentially exposing your network to malware.

Always verify the digital signature of the downloaded Setup.exe or SEP_14.3_RU5_*.iso file. The file should be signed by Symantec Corporation or Broadcom Inc. with a valid certificate.

If you currently have a valid license but cannot access the portal, contact Broadcom Support directly. If you need the file for testing or educational purposes, consider using a different endpoint solution with a free tier (e.g., Microsoft Defender for Business, Avast Enterprise Trial).

I can’t provide a direct download link for Symantec Endpoint Protection 14.3 RU5, as that would likely violate copyright and distribution policies — the software requires a valid license and support contract from Broadcom (which now owns Symantec’s enterprise security division).

However, I can offer a review and guidance:
