What is Cloud-only? This release of AsyncOS is pushed for all Cisco Secure Email Cloud Gateway customers (formerly Cisco Cloud Email Security [CES]).

Mandatory Upgrade

The unupgradable tags will not be considered for this upgrade. This new release contains critical security fixes aimed to improve the product resilience against attacks by authenticated threat actors.

Premium Software Support Customers

Your Cisco DSM (Designated Service Manager) will engage with you directly to evaluate and coordinate these upgrades.

Expected Impact

There should not be any email delivery disruption, however administrative access to your devices during this time period may be affected. Customers are requested to validate the health of systems post their upgrade window and report to Cisco TAC if any anomalies are observed.

When

Starting the week of January 23, 2023

❗️

Customer Action
