Case Study: IDOM reduces high-severity vulnerabilities with Docker Hardened Images

IDOM reduces high-severity vulnerabilities by 80% with Docker

IDOM, one of Japan's largest vehicle buyers and retailers, faced a significant challenge in standardizing security and eliminating base-image vulnerabilities across its cloud-native infrastructure following a cyberattack. With engineering teams using a wide range of images from public registries, maintaining consistent security standards and improving development efficiency became a major operational hurdle. To address this, they turned to Docker and adopted Docker Hardened Images.

By implementing Docker Hardened Images, Docker provided IDOM with a trusted, standardized container foundation. The solution involved updating Dockerfiles and establishing an internal policy mandating the use of these secure images. As a result, IDOM achieved an 80% reduction in high-severity vulnerabilities while maintaining zero Critical CVEs. They also cut their container image size by approximately 50%, which reduced cloud storage costs and shortened deployment times. This allowed developers to focus on product development instead of image assessment, creating a uniform security standard across the organization.
