HiddenLayer builds an inventory of the AI applications, models, and assets in a customer environment. HiddenLayer offers a firewall that monitors, detects, and responds in real time to adversarial threats on agentic and generative AI applications. HiddenLayer continually identifies threats and validates defenses for agentic and generative AI applications.[1]

HiddenLayer says developers are embedding AI into tools and workflows faster than security teams can track. HiddenLayer says third-party models introduce unknown code and vulnerabilities. HiddenLayer says coding agents can read sensitive files, execute shell commands, install dependencies, or expose credentials. HiddenLayer says attackers can manipulate AI systems through prompts, retrieved content, tool output, or other untrusted inputs.[1][4][5]

HiddenLayer automatically builds a living inventory of AI across an environment, including shadow AI. HiddenLayer scans cloud accounts, repos, endpoints, and pipelines to detect every model and associated agent. HiddenLayer scans AWS, Azure, GCP, VMs, containers, and APIs for AI assets. HiddenLayer automatically associates AI assets with owners, business units, sensitivity, and risk levels. HiddenLayer aligns AI assets with NIST, OWASP, and ATLAS frameworks.[6][7]

HiddenLayer probes for extraction of PHI, PII, or proprietary data. HiddenLayer simulates unauthorized actions through agent tools and APIs.[6][9][10]

HiddenLayer detects and responds to AI attacks in production. HiddenLayer monitors prompts, outputs, memory, and agent actions in real time to detect and block prompt injection, data leakage, model theft, and unsafe tool use. HiddenLayer observes and reconstructs agent interactions across tools, data, and workflows in real time. HiddenLayer detects, blocks, or redacts unsafe actions and sensitive information according to policy and platform capabilities. HiddenLayer integrates runtime detections and enforcement events with existing SIEM, SOAR, and security operations workflows. HiddenLayer extends Runtime Security into AI coding agents through lightweight, on-device integration.[5][6][10]

HiddenLayer enforces boundaries around content, toxicity, bias, and regulatory restrictions. HiddenLayer detects and prevents PII, PHI, and proprietary data exposure in generated content. HiddenLayer enforces safe, compliant, and policy aligned AI behavior across applications, models, and business units. HiddenLayer combines safety guardrails with real time threat detection and prompt injection blocking.
