MetaDefender Vault v2.1.2 Release>
Opswat
MetaDefender Vault is a cross-domain solution that enables the secure transfer of files into and out of critical networks. MetaDefender Vault prevents advanced cybersecurity threats by leveraging multiple technologies within the MetaDefender Core platform, including Deep Content Disarm and Reconstruction (Deep CDR), Multiscanning, File-based Vulnerability Assessment, Proactive Data Loss Prevention (Proactive DLP) and Threat Intelligence.

Administrators can now choose to configure the Supervisor Approval Process in such a way that a file would require up to five approvals before it is available for download. If any supervisor votes against it, the file remains locked. This multi-stage supervisor approval configuration works with both OU-based supervisors (for each Active Directory Organizational Unit the administrator promotes one or more users to supervisors) or with Group-based supervisors (for each Active Directory Group).
