Our Story
Born from the intersection of security and innovation
Founded in Oslo, Norway, Prompt Shields emerged from a simple observation: enterprises want to adopt AI, but lack the security expertise and tools to do so safely.
Our founding team brings together decades of experience in cybersecurity, AI/ML engineering, and enterprise software. We've seen firsthand how AI can transform businesses—and how quickly things can go wrong without proper safeguards.
Today, we operate across Norway and the UK, serving enterprises throughout Europe and beyond with our defence platform, attack testing services, and security tools.
