Why it matters: - Enterprise AI is moving into production faster than many organizations can secure it. - PromptHalo is aimed at helping companies monitor AI systems after deployment, when risk can become harder to see and control. - Chandoor’s background in payments, cloud infrastructure and regulated environments points to demand for security tools built for high-stakes enterprise use.
