AsyncOS is designed to automatically deploy and update the certificates needed for communications 
with cloud services used for URL filtering features. However, if for any reason the system is unable to 
update these certificates, you will receive an alert that requires action from you. 

To ensure that you receive these alerts (System type, Warning severity), see information in the online 
help or user guide about adding alert recipients. 

If you receive an alert about an invalid certificate, contact Cisco TAC, which can provide the required 
replacement certificate. Instructions for installing the certificate are in the URL Filtering chapter in the 
online help or user guide. 

For details about the connection between the appliance and the cloud URL reputation and category 
services, see the URL Filtering chapter of the user guide or online help. 

For a list of changes in behavior in the earlier AsyncOS 8.5.x for Email releases, see Cisco AsyncOS 
8.5.6 for Email Release Notes.
