A. Disable automatic agent updates and manually download the new agent installer. Distribute it via a phased GPO/SCCM rollout, requiring a reboot for all endpoints.

B. Create a new agent installation package for the updated version, upload it to an internal distribution server, and trigger an immediate deployment using a PowerShell script pushed via Intune, enforcing a user reboot.

C. Utilize the XSIAM console's 'Agent Versions' policy feature to immediately assign the new, critical agent version to all relevant agent groups. Rely on the agents' built-in update mechanism to pull and apply the update without user intervention or mandatory reboot unless explicitly required by the update.

D. Log into each endpoint remotely and manually execute the agent update command via SSH/RDP, ensuring direct oversight of the update process on critical systems.

E. Wait for the next scheduled patch cycle (typically monthly) to include the agent update, as emergency updates can be unstable and cause system issues.
