Surveillance

Agents and devices that watch, identify and track people.

Flock Safety's plate readers serve more than 5,000 US police agencies and log over 20 billion scans a month. At least 30 US cities and counties canceled or paused Flock contracts after outside agencies searched their data for immigration cases.

Registry

Two registry incidents involve surveillance

Registry incidents meet a stricter bar than the cases above: public sources name the developer, the failed control and who found it.

Exposure

15 of 17 agent types rate very significant or critical on data capture and retention or perception and sensors

From the attack surface ratings, the agent types where this risk has the widest path in.
