Gray Swan AI is a safety and security provider for the AI era, offering automated adversarial testing, continuous red teaming, and runtime AI security solutions. The company was born out of Carnegie Mellon University's pioneering AI safety research team and operates across the AI and enterprise technology sectors. It has raised $40 million in Series A funding.
The company's product suite comprises three offerings: Shade, an automated adversarial red-teaming tool designed to identify vulnerabilities before attackers can exploit them; Cygnal, a real-time runtime defense system that blocks adversarial inputs and unsafe outputs; and Arena, which the company describes as the world's largest adversarial AI red teaming community, generating threat intelligence that powers both products.
Gray Swan AI's technical domains span AI safety, adversarial testing, red teaming, runtime security, and threat intelligence. The Arena platform draws on a broad community of red teamers to continuously produce the adversarial data and insights that underpin the company's security offerings.
