Overview

HiddenLayer secures the models themselves rather than the infrastructure around them. Models can be extracted, poisoned during training, or manipulated at inference time, and none of those attacks look like anything a conventional security stack is built to notice.

It covers detection and automated response rather than a one-off audit, which suits a threat surface that changes as fast as the field does.

It sells to enterprises and does not publish pricing. It is only relevant to organisations running their own models rather than consuming an API, and the discipline is new enough that established practice for evaluating a product like this barely exists yet.
