It is time to say goodbye to ASA 5500-X series hardware appliances. After making 6.2.3 the last supported Firepower Threat Defense software release for ASA 5506-X, Cisco announced that Firepower 6.6 will be last major software release for existing ASA 5500-X hardware.
It comes at no surprise that support for new software releases is ending, as all ASA 5500-X appliances are slowly approaching their End-of-Life with 2026 being the last year in which hardware support will be available for this battle tested series of Firewall appliances.
