For many organizations, the most valuable asset is their data. Whether source code, product designs, customer records, financial results, or pricing models, every organization has information they don’t want to get in the hands of competitors, sold on darknet marketplaces, or exposed publicly. Keeping that data safe has been a challenge, until now. Cyberhaven gives organizations the tools to safeguard their data from theft or misuse. In the process, we’ve become the standard for Data Detection and Response (DDR), the category we helped create.

Amazon is guided by four principles: customer obsession rather than competitor focus, passion for invention, commitment to operational excellence, and long-term thinking. We are driven by the excitement of building technologies, inventing products, and providing services that change lives. We embrace new ways of doing things, make decisions quickly, and are not afraid to fail. We have the scope and capabilities of a large company, and the spirit and heart of a small one. Together, Amazonians research and develop new technologies from Amazon Web Services to Alexa on behalf of our customers: shoppers, sellers, content creators, and developers around the world. Our mission is to be Earth's most customer-centric company. Our actions, goals, projects, programs, and inventions begin and end with the customer top of mind. You'll also hear us say that at Amazon, it's always "Day 1." What do we mean? That our approach remains the same as it was on Amazon's very first day - to make smart, fast decisions, stay nimble, invent, and focus on delighting our customers.
