HiddenLayer
Comprehensive platform that discovers, tests, and protects machine learning models throughout their lifecycle from supply chain risks and runtime attacks.
- Also known as
- hiddenlayer
What is HiddenLayer?
A security platform that discovers AI assets, validates model supply chains against vulnerabilities and backdoors, simulates adversarial attacks on AI systems, and enforces runtime protections against inference attacks, model extraction, and model theft without requiring access to proprietary model data.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for HiddenLayer, not the verdict.
