Helps enterprises safeguard the machine learning models behind their most important products with a comprehensive security platform MoreLess

HiddenLayer is a pioneering startup in the field of AI security. The company offers a unique software solution designed to protect AI algorithms from adversarial attacks. These attacks can compromise the integrity of AI models, potentially costing businesses their competitive edge. HiddenLayer's software provides real-time monitoring of AI models' health and potential vulnerabilities, without requiring access to the model or its training data.

The company serves a broad range of clients, from small businesses to large enterprises, operating in markets where AI plays a crucial role. This includes industries like finance, healthcare, and technology, where AI algorithms are often used for decision-making, predictive analysis, and automation.

HiddenLayer's business model is based on a productized solution, which means it offers a standardized, ready-to-use product rather than a customized service. This approach allows the company to serve a larger number of clients and scale its operations more efficiently. The company generates revenue by selling its software solution to businesses that use AI and want to protect their models from adversarial attacks.

Unlike many other AI security firms, HiddenLayer does not rely on expensive expert panels to dissect and harden algorithms. Instead, it uses a cost-efficient, software-based approach that reduces complexity and cost for its clients. The company was founded by professionals with experience in machine learning and security, and it has been recognized by Gartner, a leading research and advisory company, for its contributions to AI application security.
