Because its one platform, Adaptive develops a complete risk picture and uses it automatically, applying targeted training, attack simulations, real-time interventions, and policy controls to lower risk over time. More than 1,000 organizations run Adaptive to manage their human security program, and the company has raised $150M+ from investors including NVIDIA, Andreessen Horowitz, Bain Capital Ventures, and Citi Ventures.
