April 29, 2025 Update:
Cisco is postponing the transition to a later date. We’ll share an update here once the new date is decided. Thank you for your understanding and continued partnership.
April 14, 2025 announcement:
Starting May 13, 2025, Cisco Umbrella will start transitioning its domains from using DigiCert certificates to using Identrust certificates. While we anticipate that this change will have no impact on the majority of devices and users that use software that connects to Cisco domains which are verified using DigiCert certificates, we recommend that customers verify the Identrust root certificate and connectivity requirements are met before May 13, 2025, to ensure a seamless transition and avoid potential disruption.
Action Recommended: Check root certificate installation and device connectivity
- Check for Identrust root certificate in trust store
Ensure that the Identrust root certificate is installed in the trust store of your devices. Most modern browsers and operating systems include this certificate, provided they are up to date, but this may not be the case for certain network appliances or virtual appliances.
- Confirm device connectivity
Confirm that your devices can connect to the following CRL and OCSP responder URLs associated with Identrust:
