Module update

MetaDefender Distributed Cluster (MDDC) introduces two modes of Module Update. To switch between the modes, please sign in to MDDC Control Center console, navigate to Settings and select Module Update tab.

Online update mode is enabled by default.

Online module update

In online update mode, MDDC Control Center will base its checks on the activated licenses to find and download the latest engine packages from OPSWAT online update infrastructure, repeating this process every four hours.

All downloaded engine packages are verified and stored in MDDC File Storage for licensed MetaDefender Core instances to pull, install, or upgrade on their end. Through this mechanism, the instances cease to independently pull the engine packages from the update infrastructure, conserving network bandwidth while enhancing their readiness.

Offline module update

In offline update mode, administrators must download the licensed engine packages from MetaDefender Update Downloader and upload them manually to MDDC Control Center.

Please reference here for more details about downloading engine packages from MetaDefender Update Downloader.
