HVAC, power, fire, lighting, access control — the networks inside a facility are now its softest cyber target, and on federal projects a required part of handover. Cornerstone builds that record from what the network actually contains, keeps watching it for change, and lets anyone verify it — without ever exposing the building.

Today they sit on networks — often reachable from outside — and they're a routine way into a facility and everything behind it. On a federal project, delivering a cybersecurity record for those systems isn't optional; it's a required part of turning the building over.
But that record is assembled by hand, it's usually out of date the day the doors open, and nobody receiving it can check whether the paper matches the wire. A record no one can verify is worth very little — and that is the gap Cornerstone closes.
Drawn from what the control network actually contains — not a template someone filled in.
Watched after handover, so a new device or an unexpected connection surfaces instead of hiding.
A third party can confirm the record without ever seeing the building's details.
Not a scan you run once and forget. Cornerstone is the system of record across three stages, and this website is the third one.
Assembles the cybersecurity package a facility must hand over for its control systems — drawn from real evidence and cross-checked against the live network, instead of a hand-filled binder.
After handover, the record is compared to the network as it changes. A new controller, a firmware change, an unexpected outside connection — reported, not buried in a log no one reads.
A finished record can be sealed and handed to an outsider — the government, an insurer, a lender — who verifies it right here, on their own, without any access to the building.
Paste a sealed Cornerstone record someone gave you. In seconds you'll see whether its seal is genuine and untouched. The check needs nothing but the record itself — no login, no access to the building.
The record was sealed by the party it names, and nothing in it has been altered since.
No device lists, addresses, or drawings. A record carries only fingerprints and counts.
