- Docker Hardened Images (DHI) are now free and open source, providing secure, minimal, production-ready container images.
- DHI addresses supply-chain attacks, which caused over $60 billion in damage in 2025, by offering transparency and security.
- DHI includes features like continuous security patching, FIPS/FedRAMP compliance, and extended lifecycle support for enterprises.
- Enterprises like Adobe and Qualcomm use DHI for stringent compliance, while startups leverage it for faster compliance and scalability.
- DHI is compatible with Alpine and Debian, ensuring minimal adoption friction and transparency in vulnerability reporting.
- Docker has expanded DHI to include Hardened Helm Charts and MCP Servers, with plans to extend security across the software stack.
- DHI Enterprise offers 7-day CVE remediation, customization options, and build infrastructure for secure image lifecycle management.
- DHI Extended Lifecycle Support (ELS) provides up to five additional years of security patches after upstream support ends.
- Partners like Google, MongoDB, and CNCF support DHI, integrating it into security platforms and cloud services.
- Developers can start using DHI for free, join webinars, explore documentation, or participate in Docker’s partner program.
