Release Highlight

Centralized Database Deployment Model

A brand-new shared database design is available on MetaDefender Core v4.20.0 and newer. Users can now use a single PostgreSQL database server for all MetaDefender Core instances within their network. All MetaDefender Core instances connected to the shared database need to be installed on the same Operating System (Windows or Linux).

This new feature automatically synchronizes all settings (except Single-Sign-On), workflow rules, processing history, quarantine, statistics data, update history and config history on all MetaDefender Core instances.

Users will get comprehensive visibility with combined data from all MetaDefender Core instances by switching from single-instance mode to multiple-instance mode. Here’s what the product dashboard looks like when switching the modes.

The central remote PostgreSQL server can be utilized with a built-in PostgreSQL database server installed with one of the MetaDefender Core instances in the network, or with a dedicated existing PostgreSQL database server (version 12.3 or newer is recommended). Check our user guide for detailed guidance on MetaDefender Core database server setup.

Additionally, with shared database deployment, sanitized files, quarantined files and files processed by Proactive DLP from all instances can be stored in one place resulting in better file management and saved resources. Users can set the storage on the same device or a remote device.

Users can now set Deep Content Disarm and Reconstruction (Deep CDR) advanced configurations for each workflow rules

Starting with MetaDefender 4.20.0 or newer, Deep CDR advanced settings was moved from Modules under Inventory to Workflows Rules Management under Policies. Accordingly, users can configure different sanitization processes for each workflow rule to better accommodate their security demands.

Scan-from-link feature can now work even if HEAD request fails

In the previous versions of MetaDefender Core, sending HEAD request to check metadata of a file was compulsory to enable the scan-from-link feature. The purpose of this requirement was to check if the file size was acceptable before downloading the file. However, as some web services do not support unauthorized HEAD requests, we set this requirement as optional to facilitate the scan-from-link process. When HEAD request is omitted, MetaDefender Core will download the file without checking its metadata and process the file normally. If the file is larger than the maximum size supported or the disk space is insufficient, download progress will be stopped.
