Release Updates

MetaAccess Cloud

1. Enhanced threat detection to allow administrators to configure how a file is considered a threat. Criteria can be based on the number of engines and trusted engines when a device scans threats against MetaDefender Cloud. Admins can configure a policy to leverage MetaDefender Core for Threat Detection, when used this way, MetaAccess respects scan results from MetaDefender Core: only files with a BLOCKED status will be considered as threat.
