Overview

HiddenLayer is a comprehensive AI security platform designed to protect AI assets and mitigate potential threats at every stage of the AI lifecycle. The platform features AI Discovery, which offers visibility into AI assets across multiple environments to prevent shadow AI - untracked or unapproved AI deployments.

It also includes AI Supply Chain Security to secure AI models before deployment by verifying their integrity and supply chain. Another feature, AI Runtime Security, is built to detect and respond to AI attacks without impacting production performance.

Furthermore, the platform provides an AI Attack Simulation to continuously stress test AI systems with adversarial simulations, effectively identifying weaknesses before they can be exploited by attackers.

The platform ensures secure AI rollouts, prompt attacks prevention, model extraction prohibition, and data leakage prevention. In addition, HiddenLayer offers a governance feature which aids in maintaining predictable, compliant, and policy-adherent AI across the enterprise.

It integrates with existing security and MLOps stack, making it an inclusive tool for AI security. It is designed to be model-agnostic, agentless, and requires zero training data to deploy.
