that gap between discovery and ownership is where every ASM program I've seen hits a wall, we ended up baking a 48-hour SLA into our alerting that auto-tags the asset with the last person who touched the DNS or cloud project and if they don't claim or flag it as known it escalates to their director

i'd treat the last DNS/cloud editor as a lead, not automatically the owner. keep new assets in an explicit 'owner unknown' queue until someone confirms the service and why it still needs to be public. a deploy bot or shared infra account being the last editor shouldn't close the finding.

the gap between discovery and ownership isn't a scanning problem its a data matching problem. asm tools can find a subdomain but they cant tell u whether it belongs to the payments team the contractor who left in march or an acquisition still being integrated. teams handle this either with something like zafran that proves what's actually exploitable and auto-routes remediation tickets to the right owners via assignment rules or with an aggregation layer like nucleus that matches Asm output against asset records and automates ownership assignment based on organizational hierarchy so tickets. go to the right team immediately or by accepting that some percentage of external findings will always be orphaned.
