These runtime protections work in tandem with secure container foundations. Docker’s new Hardened Images, secure, minimal, production-ready container images maintained by Docker with near-zero CVEs and enterprise SLA backing. Recent updates introduced unlimited catalog pricing and the addition of Helm charts to the catalog. We also outlined Docker’s five pillars for Software Supply Chain Security, delivering transparency and eliminating the endless CVE remediation cycle. While Hardened Images are available as a separate add-on, they’re purpose-built to extend the secure-by-default foundation that Docker Desktop provides, giving teams a comprehensive approach to container security from development through production.

Seamless Enterprise Policy Integrations

The Docker CLI now gracefully handles certificates issued by non-conforming certificate authorities (CAs) that use negative serial numbers. While the X.509 standard specifies that certificate serial numbers must be positive, some enterprise PKI systems still produce certificates that violate this rule. Previously, organizations had to choose between adhering to their CA configuration and maintaining Docker compatibility, a frustrating trade-off that often led to insecure workarounds. Now, Docker Desktop works seamlessly with enterprise certificate infrastructure, ensuring developers can authenticate to private registries without security teams compromising their PKI standards.

These improvements reflect Docker’s commitment to being secure by default. Rather than treating security as a feature developers must remember to enable, Docker Desktop builds protection into the platform itself, giving enterprises the confidence to scale container adoption while maintaining the developer experience that drives innovation.

Unlocking AI Development: Making Model Context Protocol (MCP)Accessible for Every Developer

As AI-native development becomes central to modern software engineering, developers face a critical challenge: integrating AI capabilities into their workflows shouldn’t require extensive configuration knowledge or create friction that slows teams down.
