MetaDefender Cluster™ v2.6.0 Release: Centralized Engine Management, MetaDefender Aether Integration, and Performance Improvements

System administrators can now enable, disable, or remove engines across all MetaDefender Core instances from a single location in MetaDefender Cluster. Any changes made centrally are automatically synchronized across all instances. For IT managers running distributed deployments, this eliminates the need to configure each instance individually and significantly reduces the risk of policy inconsistency across the cluster.

Cluster Worker is now bundled with the Cluster Control Center. Users can install Cluster Worker through a single script available directly in Control Center, removing the multi-step setup process that previously required separate handling. For teams deploying or scaling a cluster environment, this is a straightforward reduction in operational overhead.

MetaDefender Cluster now includes integration with MetaDefender Aether, bringing AI-powered zero-day detection into the cluster processing pipeline. This allows organizations to extend advanced threat analysis capabilities across distributed file processing environments without additional architectural changes.

Archive file generation through distributed compression is now supported across multiple MetaDefender Core instances within a cluster. This expands the scope of what the cluster can handle at scale and improves resource utilization for workflows that involve archive output.

Users can now specify custom installation directories when deploying instances through Cluster Worker, including MetaDefender Core, MetaDefender Cluster API Gateway, and Callback Service. For organizations with specific infrastructure or compliance requirements around file system layout, this removes a previous constraint that forced deployments into default paths.

Users can now search and filter the audit log using multiple criteria simultaneously, including destination, action taken, date, and time. For compliance officers and security teams who rely on audit logs for investigations or regulatory reporting, this makes retrieving the right records significantly faster.

The processing history view now includes a file size filter, making it easier to narrow down records and identify relevant scan activity. This is particularly useful in high-volume environments where sorting through large processing histories without precise filters has been a friction point.

A redesigned MetaDefender Cluster File Storage layer improves file upload and download speeds between the system and clients. For organizations processing large volumes of files across distributed infrastructure, this translates directly to better throughput and a more responsive experience for connected applications and integrations.

Executive report generation has been optimized to return results more quickly. For security and compliance stakeholders who rely on the executive dashboard for routine oversight and reporting, this reduces wait time and supports faster decision-making cycles.

The distributed extraction flow has been redesigned to make better use of system resources. Beyond the performance improvement, the redesign also addresses stability, reducing the likelihood of interruptions during high-load extraction scenarios.

Administrators can now configure the minimum number of active MetaDefender Core instances, active antivirus engines, and specific required engines that must be available before the system processes files. This gives teams direct control over system readiness thresholds and prevents file processing from proceeding in a degraded state without administrator awareness.
