  • Internal ports ranging from 30000 to 30071. Conflicts within this port range can lead to improper system behavior.
  • If you route traffic through proxy servers, there's no need to set up outbound rules for other outbound connections, except the proxy connections.
  • To ensure proper communication between product instances and the My OPSWAT Central Management, the FQDN and ports must be allowed through your firewall or proxy.

Operating System

Red Hat Enterprise Linux 9.4 or later (64-bit only).

Required Packages

Install the following packages before running the RPM installer:

PackageRequired VersionInstallation Guide
nginx>= 1.30.1nginx.org
rabbitmq-server>= 4.1.4rabbitmq.com
redis>= 8.2.1redis.io
erlang27.3.4.2 to 27.x (< 28.0.0)Bundled with rabbitmq-server (same link above)

Storage Usage Information

MetaDefender Endpoint

On average, each MetaDefender Endpoint (MDE) sends approximately 150 MB of data to Central Management per month.

To calculate the required disk space based on your data retention policy:

Required Disk Size = 150 MB × [Number of Endpoints] × [Data Retention Period in Months]

For example, to manage 1,000 MetaDefender Endpoints with 1-month data retention period:

Extra Disk Space Needed = 1,000 Endpoints × 0.15 GB × 1 Month = 150 GB

Total disk space requirement:

  • 100 GB for the operating system
  • 150 GB for endpoint data

Disk space needed to manage 1000 endpoints: 250 GB

MetaDefender Core

The required extra disk space depends on two key factors:

  1. Number of scanning engines
  2. Number of managed MetaDefender Core instances & Scanning volume

Number of scanning engines: On average, each scanning engine requires approximately 5 GB of storage in Central Management. For example, with 20 engines, you should allocate an additional 100 GB of disk space.

Number of managed MetaDefender Core instances & Scanning volume: Additional disk space is required to store scanning reports generated by MetaDefender Core. As a baseline, allocate at least 100 GB for storing these reports, with further increases based on the number of managed instances and overall scanning activity.

  • Note: On average, each file scan generates a report of approximately 10 KB. Therefore, for every 1 million scanned files, you should allocate an additional 10 GB of disk space.

For example, to manage MetaDefender Cores with 20 engines:

Extra Disk Space Needed = 100 GB for engine database + 100 GB for report storage = 200 GB

Total disk space requirement:

  • 100 GB for the operating system
  • 200 GB for engine & report data

Disk space needed to manage Cores with 20 engines & 1 million scanned files: 300 GB

Browser Versions Supported

Supported browsers for launching the My OPSWAT Central Management console are Chrome, Firefox, and Microsoft Edge on desktop (mobile view has not been supported yet, but in our roadmap). We recommend that you should use the most current version of the browser.

Screen Resolution

We recommend that you use a screen resolution of 1300x768 or larger to properly display My OPSWAT Central Management console interface.
