The 1ES (One Engineering System) team is responsible for enabling the world's best engineering teams with world-class tools and systems that help them ship products their customers love. Developers rely on many components to build software, including open-source packages, container images and infrastructure-as-code configuration files. Keeping those components up to date is paramount to every modern application's security and imposes a big cost on development teams. Moreover, the evolving environment of cybersecurity is such that new threat vectors are discovered often and require developers to quickly update their code to keep it protected.

Microsoft's mission is to empower every person and every organization on the planet to achieve more.
