Docker's Hardened Images (DHI) are now free, offering improved security for various base images. They shift responsibility for certain vulnerabilities to Docker, allowing teams to focus on their application layers. This article outlines how to integrate DHI into vulnerability management practices.

Docker has launched unlimited access to its Hardened Images catalog, providing startups and small businesses with affordable, secure software bundles that are free from known vulnerabilities. The catalog features a wide range of images and includes a seven-day patch service level agreement to ensure timely updates. This initiative aims to enhance security in the container ecosystem by making highly secure images accessible to all users.

Docker has introduced Docker Hardened Images (DHI), which are secure-by-default container images that significantly reduce the attack surface and streamline software supply chain security. These images, designed for modern production environments, are continuously updated, minimize vulnerabilities, and integrate seamlessly into existing workflows without sacrificing flexibility or usability.
