Stopped reporting
The sensor went offline — but its last reading just sits there, looking perfectly fine on every chart.
Live sensor assurance
Constant proof your sensors are working.
Sensor-Proof continuously verifies every sensor in your fleet is alive, fresh, and accurate — and shows you the proof. So a silent failure never hides behind a green dashboard again.

The blind spot
A green dashboard isn't proof.
Most monitoring shows you the last value a sensor sent. It can't tell you whether that value is still true. Three failures slip straight through:
Flatlined
Still "reporting," but it's the same number forever. The feed is alive; the sensor isn't.
Quietly wrong
Reporting plausible-but-inaccurate data as it degrades — the most expensive failure to catch late.
Sensor-Proof catches all three. Most dashboards catch none.
