CSCvx00430 | QuoVadis root CA decommission on esa |
For affected versions of the Secure Email Gateway (ESA), some Secure Sockets Layer (SSL) certificates issued from the QuoVadis root certificate authority (CA) trust chain before March 31, 2021 can no longer be renewed from this CA. Once those certificates expire or are removed from the Cisco cloud servers, functions such as Smart Licensing, Threat Grid file analysis, and IP Reputation requests communication will fail to establish secure connections to Cisco and might not operate properly.
The QuoVadis Root CA 2 Public Key Infrastructure (PKI) used by the WSA and ESA to issue SSL certificates is subject to an industry-wide issue that affects revocation abilities. Due to this issue, no new QuoVadis Root CA 2 certificates will be issued or renewed by Cisco after March 31, 2021. This affects certificate renewals on devices, Cisco cloud servers, and third-party services.
Certificates issued before the QuoVadis Root CA 2 was decommissioned will continue to be valid. However, the certificates will not renew when they expire on either the device or the Cisco cloud server. This will cause functions such as Smart Licensing to fail to establish secure connections to Cisco cloud servers.
This table shows a summary of the QuoVadis Root CA 2 certificate expiration dates for affected Cisco services.

Expiration of the QuoVadis Root CA 2 certificates affects these services with the associated symptoms.
Affected Services | Symptoms for Affected Services |
---|---|
Smart Licensing | Failure to connect to the server (Details are provided in this section) |
Threat Grid / AMP Cloud | Failure to perform file reputation checks and to upload files for file analysis |
SecureX / Cisco Threat Response | Failure to communicate to SecureX and Cisco Threat Response Cloud Services |
Talos Cloud Reputation | Failure to perform reputation checks; ESA appliances work queue will commence to back up |
Message Tracking (Click Tracking Service) | Failure to upload individual tracking events to the Cisco URL click tracking cloud service |
CRES | Failure to encrypt new messages as well as receive decrypted messages from CRES |
Cisco Secure URL Portal | Failure to perform URL rewrite functionality |
For ESA, affected devices will be unable to connect to the Smart Licensing services hosted by Cisco. Smart licenses might fail entitlement and reflect an Out of Compliance status.
The features that use Smart Licensing will continue to function for 90 days after the last successful secure connection. Some Smart Licensing symptoms are:
Note: Offline licensing, such as Permanent License Reservation (PLR) and Specific License Reservation (SLR), is not affected by the certificate change on the Smart Licensing server.
For additional information, refer to the Cisco Smart Licensing Guide and Smart Licensing Overview and Best Practices for Cisco Email and Web Security (ESA, WSA, SMA).
Cisco has migrated from the QuoVadis Root CA 2 to the IdenTrust Commercial Root CA 1 for SSL certificates. Cisco recommends to upgrade AsyncOS to one of these versions in order to add the new IdenTrust Commercial Root CA 1 certificate.
