Issued by Schellman Compliance, LLC, an accredited certification body recognized by the ANSI National Accreditation Board (ANAB) and a member of the International Accreditation Forum (IAF), the certification validates HCLTech’s enterprise-wide framework for the responsible development, deployment and governance of AI within the defined scope of its Enterprise Artificial Intelligence Management System (AIMS). The certification covers HCLTech’s AIMS across AI lifecycle processes, including support for AI-enabled services and platforms such as the flagship AI Force platform, software engineering, IT operations and business process services. This enables HCLTech to support enterprises not only to adopt AI, but govern it consistently across systems, functions and geographies.

"This isn't simply about documenting policies; it's about embedding responsible AI governance into how the business operates every day. As organizations move from AI experimentation to enterprise adoption, the ability to demonstrate disciplined governance will become a key differentiator. HCLTech has set a strong example of what that looks like." “Achieving ISO/IEC 42001:2023 certification reflects HCLTech’s commitment to building and delivering AI responsibly at scale,” said Vijay Guntur, Chief Technology Officer and Head of Ecosystems, HCLTech. “As enterprises accelerate their AI journeys, they are looking for partners who can combine innovation with rigor and trust.
