Watch your external footprint change over time — new hosts, shadow IT and disappearing assets, run after run.
Your attack surface is never static — and a one-shot scan can't see drift. heimdallX captures a timestamped discovery snapshot on every run and diffs it against the previous one, surfacing newly appeared hosts (potential shadow IT), risky new exposures, and assets that have gone dark. Nothing changes on your perimeter without you knowing.
Each run is persisted as a discovery snapshot, scoped per workspace, project and domain, and stamped with the time it was taken. Because every run is kept, heimdallX can compute the delta against your previous run rather than just describing the present.
The delta highlights hosts that newly appeared since last run, flags risky new hosts as likely shadow IT, and tracks hosts that have disappeared. A "changes since last run" banner puts perimeter drift front and centre instead of buried in a list.
Discovery history turns external attack-surface management into a continuous operating model — the way modern EASM products run weekly or daily — rather than a point-in-time audit you have to remember to repeat.
