Can I still get support for the ASA5506-K9?
Not from Cisco. The ASA5506-K9 passed its Last Date of Support (Aug 31, 2026), so Cisco TAC, hardware replacement, and SmartNet renewals are no longer available. Independent third-party maintenance can still cover the hardware itself, typically well below OEM renewal rates. Uniqcli can review your install base, confirm coverage, and quote extended support or a refresh side by side.
