To understand how to defend attacks, one must first learn how to attack defenses.

Mindgard’s philosophy is grounded in offensive security. By emulating how attackers scope, plan, and exploit AI systems, the platform helps organizations understand exposure, assess exploitability, and reduce risk from evolving, agentic AI threats.

Organizations are rapidly adopting AI technologies, embedding them into production environments without full visibility into how their probabilistic and opaque behaviors introduce exploitable risk. Mindgard addresses this challenge by providing AI security solutions that help enterprises secure AI models, agents, and applications across the AI lifecycle. Spun out of more than a decade of AI security research at Lancaster University and headquartered in Boston and London, Mindgard enables organizations to identify, assess, and mitigate real-world AI threats.
