## What is HiddenLayer?

HiddenLayer builds a security platform for AI systems, covering threats to machine learning models and, more recently, runtime protection for autonomous AI agents.

## Key capabilities

- Security for AI models across their lifecycle.
- Runtime security capabilities for agentic and autonomous AI execution (announced 2026).
- An annual AI Threat Landscape report.

## Why it matters for humanoid robot security

Humanoid robots increasingly run AI models and agents that turn instructions into physical actions. Attacks on those models, such as prompt injection or tampered models, become physical risks. AI security platforms like this one sit at that layer. HiddenLayer announced a $100M Series B in 2026.

## Where it fits in a humanoid robot security program

HiddenLayer protects the AI layer of a humanoid: the models and agents that turn instructions and sensor data into decisions. It is most relevant once a robot relies on machine learning models or LLM-based agents, where threats include tampered models, prompt injection and attempts to extract or manipulate a model.

## Who it is for

- Robotics teams using LLMs or AI agents to plan robot actions
- Security teams responsible for AI models in production
- Organizations that already standardize on enterprise AI security tooling

## Questions to ask HiddenLayer

- Can you protect models that run on the robot itself, not only in the cloud?
- How do you detect prompt injection that arrives through speech, images or sensor data?
- What latency do your controls add to a robot's decision loop?
- How do you log and report AI incidents for later investigation?
