HiddenLayer
Why They Matter
HiddenLayer produces the most comprehensive annual threat intelligence on AI-specific attacks. Its 2026 AI Threat Landscape Report ā the definitive source on agent breach data ā found that autonomous agents now account for more than 1 in 8 reported AI breaches. As the only security company focused exclusively on protecting AI systems (rather than using AI for security), HiddenLayer provides ground-truth data on what AI attacks actually look like in production.
Background
HiddenLayer was founded to address a gap in enterprise security: existing tools were designed to protect against attacks on software, not attacks on AI models and systems. Model theft, adversarial examples, data poisoning, and agent hijacking require fundamentally different detection and response approaches. The company's 2026 threat report is the primary source for practitioners assessing the risk profile of deploying AI agents in regulated environments.
