HiddenLayer AI Runtime Security
Austin, Texas
What it is
HiddenLayer AI Runtime Security protects AI applications, agents, and agentic workflows in production through runtime visibility, threat detection, and policy-based enforcement. It detects and investigates prompt injection, unsafe agent behavior, sensitive data exposure, malicious tool use, and other runtime threats. Depending on policy and platform support, teams can block or redact unsafe actions and sensitive information. Agentic Runtime Security reconstructs sessions and lets investigators search across sessions, tools, and execution paths. Deployment options include APIs, gateways, SDKs, and lightweight on-device integrations, including protection for coding agents. Listed integrations cover LangChain, LiteLLM, the OpenAI Agents SDK, AWS Strands, and TrueFoundry’s gateway. AWS coverage includes Bedrock models and agents, SageMaker models and endpoints, and Bedrock AgentCore agents using AWS Strands. Events can feed SIEM, SOAR, and security operations workflows. HiddenLayer lists SOC 2 Type II and ISO 27001 compliance. Pricing is on request and a demo can be requested.
