HiddenLayer

2026 AI Threat Landscape Report Backed by patented technology and industry-leading adversarial AI research, our platform provides AI Discovery, AI Supply Chain Security, AI Attack Simulation, and AI Runtime Security. Developers are embedding AI into tools and workflows faster than security teams can track, leaving blind spots that grow before anyone notices. Third-party models introduce unknown code and vulnerabilities, and it’s hard to secure what you didn’t build yourself. Traditional tools can’t test or predict how applications behave under pressure, making it hard to know if your defenses actually work. Most organizations lack the tools and plans to detect or respond when AI systems are compromised. Our platform proactively defends against the full spectrum of AI threats, safeguarding your IP, compliance posture, and enterprise operations. Identify and build an inventory of the AI applications, models, and assets in your environment. Analyze, identify risks, and protect your AI applications, models, and assets as you build. Continually identify threats and validate defenses to safeguard agentic and generative AI applications at scale. Firewall to monitor, detect, and respond real-time to adversarial threats on agentic and generative AI applications. Simplified deployment with pre-built integrations into CI/CD, MLOps, Data Pipelines, and SIEM/SOAR. Reduction in exposure to AI exploits Disclosed through our security research Secure your AI with precision-built defenses. Detect hidden risks in third-party and proprietary models. Identify threats early and validate defenses continuously. Prevent misuse, data leakage, and adversarial attacks with policy-based controls. Safeguard autonomous systems and protect against rogue behavior. Address your AI Security needs by a specific industry or role. Securely Innovate with AI for Fraud Detection, Trading, Compliance, and Customer Engagement. Accelerate AI innovation, safely and confidently. Protect Agentic, Generative, and Predictive AI Systems for Mission Assurance. Enable Safe and Scalable AI Adoption. Build AI applications securely without compromising speed or flexibility. As enterprises embrace AI, security can’t be an afterthought. HiddenLayer makes it possible for CISOs to lead with confidence and keep innovation secure. Securing AI requires protection across the entire lifecycle. HiddenLayer delivers end-to-end visibility and defense so CISOs can safeguard AI at every stage. Strong governance is critical as AI becomes embedded across enterprises. HiddenLayer provides the comprehensive framework needed to manage risk and align AI adoption with visibility, compliance, and accountability. The integrity of AI systems is as critical as the integrity of our software supply chains. If we can't secure the building blocks of AI, we risk exposing enterprises to new classes of attack. HiddenLayer is tackling this problem at its root, delivering the protections the world nee
