Energy clients are the digital eyes and hands of the grid. Leaving even one unpatched is akin to leaving a substation door unlocked in a hostile neighborhood. As we modernize toward a renewable, distributed, and interconnected energy future, the discipline of patching will determine whether that future is resilient or fragile.

So next time you see the headline “Energy Client Patched Against Critical Flaw,” take a moment to appreciate the silent, coordinated effort of engineers who prevented yet another crisis—often without the public ever knowing there was a risk. Subscribe to CISA’s ICS-CERT alerts and your regional ISO’s threat feed. Set a calendar reminder for the second Tuesday of each month to review all outstanding energy client patches. Your grid depends on it.
