In Sophos UTM 9.5, a new feature is introduced to send a notification alert when any of the certificates present on the UTM appliance are within 30 days of expiry. This notification will look similar to the following:
1 certificate(s) will expire within the next 30 days: Proxy CA -- System Uptime : 0 days 12 hours 12 minutes System Load : 0.35 System Version : Sophos UTM 9.500-9 Please refer to the manual for detailed instructions.
1 certificate(s) will expire within the next 30 days: Proxy CA
-- System Uptime : 0 days 12 hours 12 minutes System Load : 0.35 System Version : Sophos UTM 9.500-9
Please refer to the manual for detailed instructions.
Proxy CA in the above example is the name of the certificate in question.
For manually imported verification Certificate Authority (CA), the name in the notification may not be enough to identify the certificate immediately. This notification triggers if any of the certificates within the UTM's certificate store are within 30 days of expiry, regardless if certificates are in use by the current configuration or not.
The following sections are covered:

If the certificate is still not identified then it is likely that no action is required. However, the following process can be used to identify the cause of the alert:
