Cognizant is one of the world's leading professional services companies, transforming clients'​ business, operating and technology models for the digital era

Our unique industry-based, consultative approach helps many of the best-known organizations in every industry and geography envision, build and run more innovative and efficient businesses.

Founded in 1994 as a technology development arm of The Dun & Bradstreet Corporation, we were spun off as an independent company in 1996, and have worked closely with large organizations to help them build stronger businesses ever since. Today, Cognizant engineers modern businesses to improve everyday life, helping some of the world’s most established companies remain the most loved brands. In today’s fast-changing technology landscape, we work with our clients to advance every aspect of how they serve their customers: digitizing their products, services and customer experiences; automating their business processes; and modernizing their technology infrastructures.

Put simply, we help clients harness digital to address their daily needs and keep their businesses relevant. As the partner they turn to execute on their digital priorities, we focus on IoT, AI, software engineering and cloud — the technologies that are changing the nature of business.

Today, creating value by leveraging technology is very industry-specific, so we continue to deepen our expertise in 20 different industries, including banking and financial services, healthcare, manufacturing and retail. And to help speed clients’ journeys toward becoming digital, we bring our digital capabilities and industry expertise together into horizontal offerings and industry solutions that accelerate the most essential leaps that today’s technology makes possible, and complement those solutions with consulting and services built for the speed of business today.

We’re committed to building digital talent all around the globe so everyone can benefit from the full spectrum of human ingenuity. We collaborate locally with clients, in person and in their local languages. We consider it our responsibility to make people feel at home in the future, no matter how technology-enabled it becomes. So, we are committed to helping to solve some of humankind’s most difficult challenges in a way that is beneficial and comfortable for people through the work we do, and through investing in training people around the world in the digital skills that will be needed to do that work.

We believe that the opportunity presented by technology has never been greater, and because of that opportunity, Cognizant will continue to collaborate with clients to modernize their businesses, making everyday life ever better for them, their customers and the communities they serve. At Cognizant, we are focused on understanding challenges, aware of opportunities, driven to solve for you. We are shaped by a diverse group of entrepreneurial people working together to create a better way with you. We have clarity of purpose, enduring values and an unwavering commitment to our clients drive sustained business performance over the long term.
