Twelve terminals, one inventory, and the end of the quarterly surprise

Harlowe ran four separate asset lists and still found production systems during penetration tests. Ten months later the security team briefs the board from a single number nobody disputes.

The challenge
  • Four asset inventories maintained by four teams, none of them complete and none of them agreeing.
  • Terminal operations ran on networks the central security team could see only through a change ticket.
  • Penetration tests kept finding internet-facing systems that no inventory listed.
The approach
  • Discovery was connected before any policy work, so the first month produced an inventory rather than an argument.
  • Ownership was resolved team by team; 91% of assets had a confirmed owner within six weeks.
  • Only paths terminating at a Core asset were escalated. Everything else went into the normal backlog.
The outcome
  • The last two penetration tests found no unlisted internet-facing systems.
  • Terminal networks are inventoried continuously rather than at audit time.
  • The board brief went from 14 slides to two pages with one score and one trend line.

We stopped arguing about which list was right. That argument had been eating a day a week for three years.
