Why is duosys.net marked "Suspicious Website"?

The listed status means the domain currently appears in Gridinsoft's own Threat List; it is not a consensus of external providers. 11 of 27 publicly displayed security sources report a warning. A separate license-restricted partner security signal also contributes to the automated assessment; its provider name and verdict cannot be displayed publicly under the source license.
