HiddenLayer protects AI models from adversarial attacks, model theft, and evasion techniques with a model-agnostic security layer requiring no architecture changes.
About
HiddenLayer is an AI security company founded in 2022 that raised $50M in Series A funding to protect machine learning models from adversarial attacks and exploitation. The platform sits between AI models and the inputs they receive, monitoring for adversarial examples, prompt injection attacks, model inversion attempts, and evasion techniques designed to manipulate model outputs. HiddenLayer also protects against model theft through model extraction detection and intellectual property protection controls that alert teams when adversaries attempt to clone proprietary models. The platform is model-agnostic and integrates with existing ML infrastructure without requiring changes to model architectures or inference pipelines. HiddenLayer serves enterprises in financial services, defense, and technology sectors where AI models process sensitive data or make high-stakes decisions. The company's security research team regularly publishes findings on novel AI attack techniques, building credibility as a thought leader in AI security alongside its commercial platform.
Delinea is a privileged access management platform delivering secrets management, privilege elevation, and session controls across cloud, on-premise, and hybrid environments.
About
Delinea is a privileged access management (PAM) company headquartered in Redwood City, California, formed in 2021 through the merger of Thycotic and Centrify — two established PAM vendors whose combination created one of the largest independent players in the privileged access security market. The merger was backed by TPG Capital and brought together Thycotic's Secret Server vault and cloud PAM capabilities with Centrify's identity-centric privileged access controls and zero trust architecture, creating a unified platform that addresses the full spectrum of PAM use cases: vaulting and rotating privileged credentials, enforcing just-in-time privilege elevation, recording and auditing privileged sessions, and managing machine and application secrets at scale.
