AI/ML model security platform
HiddenLayer protects model artifacts and the ML supply chain. SoterAI protects the runtime behavior of the AI applications you ship — input, output, RAG, and agents.
HiddenLayer is focused on AI asset and model security: model scanning, inventory, attack simulation, and ML supply-chain protection for enterprise AI assets. SoterAI operates at the application layer — it intercepts prompts and responses, scans RAG context, authorizes agent tool calls, and enforces policy at request time. The two are complementary; this page covers where SoterAI is the faster, lighter fit for app-layer guardrails.
HiddenLayer is stronger for protecting model artifacts themselves — model inventory, adversarial ML detection, attack simulation, and supply-chain security across the enterprise AI estate.

Choose SoterAI when
You need to secure both the runtime behavior of chatbots/RAG/agents AND scan the model artifacts you ship for malicious serialization.
Choose HiddenLayer when
Your priority is deep adversarial ML attack simulation and enterprise-wide AI asset inventory.
Fire a prompt-injection or PII attack in the live playground and watch SoterAI block it in under 50ms.
