Upgrade Firepower Devices before March 5th 2022 – Field Notice: FN – 72332

If you use the Cisco Firepower Security Intelligence services and are using versions ranging from 6.1 to 7.1 then this field notice may be for you. After March 5th 2022, Security Intelligence updates will fail because the CA certificate used to obtain updates from Talos will be decommissioned. That means SSL communication to will fail and thus cause the failure of IP, DNS and URL updates.

The recommendation is to update your Firepower Management Center (FMC) and/or the Firepower Device Manager (FDM) to a version that contains a fix. The Firepower Threat Defence (FTD) device that is managed by the FMC isn’t required to be updated however, you may choose to plan your upgrade to ensure that software versions between the FMC and FTD are aligned.

More details can be found in Field Notice 72332 and Fixed Releases can be found under bug CSCwa70008.
