description: 'HiddenLayer is an Austin, Texas-based AI security company founded in March 2022 by Chris Sestito (CEO), Tanner
  Burns (Chief Scientist), and Jim Ballard (CIO) — former Cylance researchers who encountered a real-world attack on production
  ML models. HiddenLayer builds an AI Security Platform that protects machine learning and generative AI systems across their
  entire lifecycle, comprising four integrated modules: AI Discovery (catalogs AI assets and eliminates shadow AI), AI Supply
  Chain Security (Model Scanner inspects models, weights, and pickle/RDS files for malicious payloads and backdoors), AI Attack
  Simulation (continuous adversarial red-teaming for agentic and generative systems), and AI Runtime Security / AIDR (a real-time
  detection-and-response firewall using deterministic classifiers that sit outside the model inference path to detect prompt
  injection, jailbreaks, indirect attacks, data leakage, and malicious tool calls in agentic and MCP systems). The platform
  exposes native connectors for CI/CD, MLOps, SIEM/SOAR, API gateways, and major data and cloud platforms, plus guardrail
  integrations for OpenAI Agents, LangChain, AWS Strands, Microsoft Agent Framework, Azure APIM, and a GitHub Action for Model
  Scanner. HiddenLayer publishes Python, TypeScript, and Java/Kotlin SDKs and research-grade tooling such as HiddenPickle
  (Python pickle disassembler/patcher) and HiddenPromise (R .rdx/.rdb/.rds disassembler). The company has raised $56M total
  ($50M Series A in September 2023 led by M12 / Microsoft''s Venture Fund and Moore Strategic Ventures, with Booz Allen Ventures,
  IBM Ventures, Capital One Ventures, and Ten Eleven Ventures participating) and serves Fortune 500 enterprises, financial
  services, and US Federal agencies. The HiddenLayer SaaS console and REST API are gated behind enterprise sales and not publicly
  self-serve, placing this profile in Tier-3 (enterprise-gated) coverage.'
