Name

Editions

Supported

SQL Server 2017

All

Yes

SQL Server 2019

All

Yes

Windows Authentication (Integrated Security) is not a supported authentication mechanism.
An SQL Server local account must be created with at least the following server roles (public, sysadmin).

Web server configuration

NGINX is used as our underlying HTTP(S) and reverse proxy server. The web server is embedded in the application and is not shared by other processes running on the machine. All NGINX processes will be stopped, and the program itself physically removed from the hard drive, following a successful uninstall of MetaDefender Vault.

On startup, the web server will begin listening on the previously configured HTTP(S) port or on the default HTTP port (8010 if free), in case of a clean install.

Following MetaDefender Vault version 1.3.7, REST API calls should be made to the Web UI port.
The reason is that the REST API service connection is no longer secured (TLS/SSL connections are no longer supported).
NGINX acts as a TLS/SSL termination proxy for the REST API service.

Port usage

MetaDefender Vault requires two free ports in order to run:

Service name

Port

Firewall Rule

MetaDefender Vault Web UI

Needed

MetaDefender Vault REST API

8000

Not needed;
Internal usage only

Whitelisting requirements

  • In order to be able to access the user interface from outside, the port 8010 (default) should be opened

  • Any process running out of the MetaDefender Vault install directory should be whitelisted. It is best to exclude the folder from any real-time protection

  • File storage (permanent and temporary) or the installation folder should be excluded from real-time protection
