About HiddenLayer

HiddenLayer sells AI security that analyzes AI applications, models, and assets, identifies their risks, and protects them as teams build. 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 analyzes models for malware, vulnerabilities, backdoors, and unknown components before they reach production. HiddenLayer scans model files and URLs for malware, CVEs, backdoors, and integrity issues before deployment. HiddenLayer analyzes architectures, layers, weights, and artifacts for tampering or anomalies. HiddenLayer tests commercial models for safety and security before integration. HiddenLayer identifies where models come from, including origin and licensing.[4][6][7][8]

HiddenLayer continuously tests AI systems against evolving attacks and uncovers weaknesses early. HiddenLayer tests for jailbreaks, injection, role confusion, and harmful response patterns. 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. HiddenLayer protects autonomous agents and MCP based systems from prompt injection, unsafe tool use, and harmful autonomous actions.[1][6][11]

HiddenLayer says its platform deploys across any architecture without exposing intellectual property, weights, prompts, or customer data. HiddenLayer offers deployment through APIs, gateways, SDKs, or lightweight on-device integrations. HiddenLayer offers services modeled after active adversarial campaigns targeting enterprise AI applications. HiddenLayer services evaluate every layer from AI asset discovery to data and model supply chains to runtime environments. HiddenLayer services provide detailed remediation playbooks tailored to models, infrastructure, and compliance needs. HiddenLayer services work in concert with the HiddenLayer AI Security Platform for ongoing protection. HiddenLayer services align with emerging AI governance standards, including NIST AI RMF and EU AI Act requirements.[4][6][12]

HiddenLayer describes securing AI used for fraud detection, trading, compliance, and customer engagement. HiddenLayer describes establishing governance controls aligned with FFIEC and OCC frameworks. HiddenLayer detects malware, tampered artifacts, and backdoored weights in pretrained models and libraries. HiddenLayer protects agentic, generative, and predictive AI systems for mission assurance.[1][4][6][10][13]
