ASA 9.16 EOL

[bobbycameron]

I'm getting conflicting information from an "engineer" I work with about the ASA 9.16.4 being EOL. I cant find an EOL statement online anywhere but he states he spoke to Cisco and they told him 31 Aug 2026.

Any help greatly appreciated

@bobbycameron I cannot find an EOL notification for 9.16 either - https://www.cisco.com/c/en/us/products/security/asa-firepower-services/eos-eol-notice-listing.html

9.17 is EOL, but that doesn't mean 9.16 is EOL. 9.16 is an extra long term release - https://www.cisco.com/c/en/us/products/collateral/security/firewalls/bulletin-c25-743178.html so will be in support to 2026.

As @Rob Ingram correctly noted, the lifecycle document is the general guidance. Since ASA 9.12 was released in May 2021, we would expect support until mid-2026. The formal EoS announcement for software would not be expected until ~2 years prior to the last date of support.

Thanks guys, I really appreciate the feedback. We track the EOL status of OS's for a large organization and wanted to be sure before stating anything!!
