Can I still get support for the ASA5508-K9?
Not from Cisco. The ASA5508-K9 passed its Last Date of Support (Aug 31, 2026), so Cisco TAC, hardware replacement, and SmartNet renewals are no longer available.

Uniqcli can review your install base, confirm coverage, and quote extended support or a refresh side by side.
