Enterprise LLM Security Testing and Protection

Gray Swan, founded in 2023 in Pittsburgh, Pennsylvania, is an emerging force in model security and AI safety engineering, focused on protecting AI deployments from both malicious adversaries and unintentional misuse. The company builds tools that evaluate operational risks, enforce safety policies, and harden AI models against a wide range of modern threats, including prompt injection, external tool abuse, retrieval-layer vulnerabilities, model misuse, and attacks from well-resourced adversaries.

Gray Swan’s flagship product, Cygnal, acts as a real-time AI safety layer. It applies advanced input and output filtering, continuous monitoring, and policy enforcement to ensure that AI endpoints behave safely and consistently with organizational requirements. Cygnal is designed for high-performance, multimodal environments and can adapt dynamically to new threat attempts without requiring heavy integration overhead. Its flexible policy system allows enterprises to enforce guardrails while maintaining the performance and interactivity that modern AI applications demand.

A defining feature of Gray Swan’s approach is the Gray Swan Arena, a dedicated AI red teaming environment that hosts large-scale adversarial challenges. Participants attempt to break AI systems through techniques such as prompt injection, ethical boundary violations, policy subversion, and exfiltration attacks. This arena-first methodology gives Gray Swan continuous insight into emerging attack vectors and informs the company’s safety research and product enhancements.

Gray Swan has reportedly raised at least $5 million in capital and is already generating revenue.
