What is HiddenLayer?
HiddenLayer is the leading provider of Security for AI, offering a comprehensive AI Security Platform (AISec) that protects agentic, generative, and predictive AI applications across the entire lifecycle. The platform unifies AI Discovery, AI Supply Chain Security, AI Attack Simulation, and AI Runtime Security to detect, prevent, and respond to adversarial AI threats without requiring access to private data, model weights, or algorithms.
Key features include AI Discovery to build an inventory of AI assets and eliminate shadow AI, AI Supply Chain Security to scan models for malware, vulnerabilities, backdoors, and integrity issues before deployment, AI Attack Simulation for continuous red teaming to validate defenses, and AI Runtime Security as a real-time firewall that monitors prompts and responses to detect prompt injection, jailbreaks, data leakage, and adversarial attacks. The platform also offers AI Guardrails for policy-based controls, Model Scanning for third-party and proprietary models, and specialized protection for autonomous agents and MCP-based systems.
HiddenLayer is designed for enterprise organizations across private and public sectors, including CISOs, AI executives, financial services firms, US federal agencies, technology companies, and application developers. It is particularly valuable for regulated industries like finance and healthcare where data privacy is paramount, as well as for organizations deploying AI at scale who need to protect intellectual property, ensure compliance, and enable safe AI adoption.
HiddenLayer pricing
Pricing model: Freemium
HiddenLayer uses custom enterprise pricing with no publicly disclosed free tier. On AWS Marketplace, a 12-month contract for the full HiddenLayer AISec Platform is listed at $5,000,000. Pricing is based on contract duration and terms with the vendor, entitling customers to a specified quantity of use. Custom pricing options require requesting a private offer or demo. The platform is delivered as SaaS with native integrations into cloud, CI/CD, data platforms, SIEM/SOAR, API gateways, and MLOps tools. Additional AWS infrastructure costs may apply separately.

- Relatively new company founded in 2022 with limited long-term track record
- Specialized AI security focus may not replace existing traditional security tools
Frequently asked questions about HiddenLayer
What is HiddenLayer's AI Security Platform?
HiddenLayer's AISec Platform is the most comprehensive security solution built specifically for artificial intelligence. It unifies AI Discovery, AI Supply Chain Security, AI Attack Simulation, and AI Runtime Security to protect agentic, generative, and predictive AI applications across the entire lifecycle. The platform detects and responds to adversarial AI threats like prompt injection, model theft, and supply chain compromise without requiring access to private data or models.
How does HiddenLayer protect AI without accessing my models or data?
HiddenLayer uses a patented non-invasive approach that analyzes patterns in ML model traffic through contextless vectorized data points. Their AI Runtime Security operates between applications and models, inspecting prompts and responses in real time using purpose-built deterministic classifiers that sit outside the model's inference path entirely. This provides robust protection without ever needing insight into customer data, proprietary models, weights, or training sets.
What types of AI threats does HiddenLayer detect?
HiddenLayer detects the full spectrum of AI threats including prompt injection attacks, jailbreaks, adversarial AI attacks, model theft, data exfiltration, ransomware targeting AI models, graph-level backdoors (like ShadowLogic), control-vector injections, embedded malware, serialization exploits, poisoning indicators, and unsafe autonomous agent behavior. Their research has also exposed vulnerabilities like EchoGram token tricks that bypass AI guardrails.
What is the difference between AI Supply Chain Security and AI Runtime Security?
AI Supply Chain Security operates at build time and ingest, analyzing models before deployment to identify malware, vulnerabilities, backdoors, and integrity issues through static analysis. It generates an AI Bill of Materials for governance. AI Runtime Security operates in production as a real-time input/output monitor that detects and responds to attacks as they happen, including prompt injections, jailbreaks, and data leakage. Both are needed because supply chain security addresses pre-deployment risks while runtime protection catches attacks that play out during execution.
Does HiddenLayer work with agentic AI systems?
Yes, HiddenLayer provides specialized Agentic and MCP Protection to safeguard autonomous systems from prompt injection, unsafe tool use, and harmful autonomous actions. Their runtime security provides session-level visibility, tool-call inspection, and enforcement actions during execution. This is critical as agentic AI has moved from experimentation to enterprise reality, with systems now browsing, executing code, calling tools, and initiating workflows on behalf of users.
What industries and roles use HiddenLayer?
HiddenLayer serves Financial Services (for fraud detection, trading, compliance, customer engagement), AI Executives, US Federal agencies (for mission assurance), CISOs, Technology companies, and Application Developers. It is particularly valuable in regulated industries like finance and healthcare where data privacy is paramount, as well as federal agencies. Testimonials include CISOs from NFL, GitLab, AIG, and other enterprise leaders.
How does HiddenLayer's red teaming capability work?
HiddenLayer's AI Attack Simulation continuously simulates real-world AI attacks to uncover weaknesses early and validate defenses. This replaces the need for expensive expert panels to manually test algorithms. The platform uses MITRE ATLAS framework alignment to test against industry-leading authority on adversarial threats targeting AI systems, enabling continuous testing against evolving attacks to strengthen resilience.
What integrations does HiddenLayer support?
HiddenLayer offers simplified deployment with pre-built native integrations into CI/CD pipelines, MLOps platforms, Data Pipelines, SIEM/SOAR systems, API gateways, and cloud platforms. These connectors allow the platform to integrate seamlessly into existing security and machine learning operations stacks without adding unnecessary complexity.
Is HiddenLayer recognized by industry analysts?
Yes, HiddenLayer is a Gartner-recognized Cool Vendor for AI Security and is validated by Gartner, RSAC, and leading industry analysts for innovation and leadership in AI security. The company has issued patents for their technology and disclosed significant security research including the EchoGram report that exposed fundamental flaws in AI guardrails across nine major AI companies.
What is the 2026 AI Threat Landscape Report about?
HiddenLayer's 2026 AI Threat Landscape Report examines how the threat landscape has shifted with agentic AI moving from experimentation to enterprise reality. Key findings include: the rise of autonomous agent-driven systems, a surge in shadow AI across enterprises, growing breaches originating from open models and agent-enabled environments, and why traditional security controls struggle to keep pace. The report reveals attacks on AI systems are steady or rising across most organizations, and shadow AI is now a structural concern.
