Cafodd Polisi Dosbarthiadau Diogelwch y Llywodraeth (GSCP) ei ddiweddaru er mwyn mynd i'r afael â bylchau’r polisi blaenorol. Mae'r polisi yn berthnasol i unrhyw wybodaeth neu ddata sy'n cael ei greu, ei brosesu, ei storio neu ei reoli fel rhan o gontract gan y llywodraeth, gan gynnwys contractau Llywodraeth Cymru fel corff Llywodraeth Ganolog.
The Government Security Classifications Policy (GSCP) has been updated to address gaps in the previous policy. The policy applies to any information or data that is created, processed, stored or managed as part of a government contract, including Welsh Government contracts as a central government body.
