Broadcom released Symantec Endpoint Protection (SEP) 14.3 RU10 on February 3, 2025.

This version focuses on simplifying management and strengthening defenses against modern "Living Off the Land" (LOTL) attacks.
On-Premises Adaptive Protection: Admins can now configure and manage Adaptive Protection policies directly from the Symantec Endpoint Protection Manager (SEPM) instead of requiring a cloud-only setup. This includes a visual heat map to track MITRE techniques and prevalent behaviors.
Enhanced Ransomware Defense: To prevent unauthorized tampering, a site-level default client password is now required during installation to stop or uninstall the client service.

Streamlined Uninstallation: A new option allows administrators to disable the "Required a password to uninstall" setting specifically to facilitate bulk uninstalls via PowerShell or command-line scripts. How to Download Symantec Endpoint Protection 14.3 RU10
