The standalone updater for the 2021-001 Catalina Security Update is now available at :

Still waiting for the Mojave 2021-001 Security Update standalone updater.

The Mojave 2021-002 Security Update has been released and apparently includes the content of and supersedes 2021-001. Will wait for the standalone updater for this update now.
