Release Highlights

Brand-New Central Hub Architecture

OPSWAT is committed to continuously innovating and enhancing our products to better serve our customers’ needs and meet organizations’ security infrastructure and policies.

Understanding users’ increasing need for large-scale deployment, MetaDefender Core v5.3 introduces a new Central Hub architecture with high-powered, auto-scaling capability, high availability, and fault tolerant.

Also, this architecture helps MetaDefender Core automatically adjust workload resource to match demand and maintain steady performance at the lowest possible cost.

The Central Hub architecture incorporates MetaDefender Core, PostgreSQL database server, and newly added components running as service:

  • MetaDefender Core Hubs (Central Hubs)
  • MetaDefender Core NAS (Network-Attached Storage).
  • Redis (the open-source caching server).
  • RabbitMQ (the open-source messaging broker).

The architecture supports single/multiple MetaDefender Core Hub(s) behind a load balancer. New MetaDefender Core instances and MetaDefender Core Hub instances can connect to the master MetaDefender Core Hub to fetch credentials to related components (RabbitMQ, Redis, Postgres server, Storage server), then make connections and start their designed functionalities.

Users can manually configure new MetaDefender Core instances and/or MetaDefender Core Hub instances to connect directly to related services without the master.

Platforms supported:

  • Linux: Red Hat Enterprise 7.x, 8x / CentOS 7.x; Debian 9.x, 11.x / Ubuntu 18.04, 20.04 
  • Windows: Windows 10, Windows server 2016 or above
