Hi Stefan,

today Netskope DNS security is not meant to be a fully comprehensive DNS filtering solution, so it lacks the ability to block "everything" unless explicitly allowed in the "Allow List".
As part of the DNS Security improvements we're looking to expand the DNS Security capabilities introducing APIs for the Allow and Block Lists management, potentially expand the DNS Categorisation outside Security categories, etc. 
The use case you describe is indeed a possible valid use case for DNS Security, so I ask you to work with your Netskope representatives to create an Enhancement Request (ER) for the ability to specify a DNS profile that blocks all requests except for records, domains and FQDNs in the Allow List.
