HiddenLayer AI Guardrails

What HiddenLayer AI Guardrails is

HiddenLayer AI Guardrails applies safety, compliance, and policy controls to LLMs, agents, and AI applications. It addresses toxicity, bias, regulatory restrictions, prompt injection, data leakage, and exposure of sensitive information, including PII, PHI, and proprietary data. It can inspect MCP and framework traffic for threats and block prompt injection in real time. The platform is model-agnostic and agentless, requires no training data, and is designed to operate across architectures without exposing intellectual property, model weights, prompts, or customer data.

Its broader lifecycle coverage includes AI Discovery, AI Supply Chain Security, AI Attack Simulation, and AI Runtime Security. Connectors include GitHub Actions, Splunk, Microsoft Sentinel, JFrog Artifactory, Databricks Unity Catalog, Hugging Face gated repositories, AI gateways, and webhooks. AWS support covers Bedrock models and agents, SageMaker models and serving endpoints, and Bedrock AgentCore agents using AWS Strands. Deployment options include cloud, on-premise, and hybrid environments, as well as AWS, Microsoft Azure, and Google Cloud marketplaces. HiddenLayer was founded in March 2022 and is based in Austin, Texas. Pricing is on request; the listed platform plan is $5,000,000 a year on a 12-month contract, with additional AWS infrastructure costs possibly applying.
