Palo Alto end of life runs on two clocks. Software: PAN-OS 11.2 dies May 2, 2027 — one day before the older 11.1 — and 10.2 already passed August 27, 2025. Hardware: the PA-5250 (PA-5200 Series) reached end of sale August 31, 2023 and hits hardware EOL August 31, 2028, capped at PAN-OS 11.2 forever. Every version's dates, the 12-entry CISA KEV record, and where to land.
