We recently announced the integration between Mend.io and Docker Hardened Images (DHI) provides a seamless framework for managing container security. By automatically distinguishing between base image vulnerabilities and application-layer risks, it uses VEX statements to differentiate between exploitable vulnerabilities and non-exploitable vulnerabilities, allowing your team to prioritize what really matters.
TL;DR: The Developer Value Proposition
The hallmark of this integration is its zero-configuration setup.
Automatic Detection: Mend.io identifies DHI base images automatically upon scanning. No manual tagging or configuration is required by the developer.
Visual Indicators: Within the Mend UI, DHI-protected packages are marked with a dedicated Docker icon and informative tooltips, providing immediate transparency into which components are managed by Docker’s hardened foundation.
Transparent Layers: Users can inspect findings by package, layer, and risk factor, ensuring a clear audit trail from the base OS to the custom application binaries.
Dynamic Risk Triage: VEX + Reachability
Standard scanners flag thousands of vulnerabilities that are present in the file system but never executed. This integration uses two layers of intelligence to filter the noise:
Risk Factor Integration: Mend.io incorporates Docker’s VEX (Vulnerability Exploitability eXchange) data as a primary source of “Risk Factor” identification.
The “Not Affected” Filter: If a CVE is marked as not_affected by Docker’s VEX data or determined to be Unreachable by Mend’s analysis, it is deprioritized.
Bulk Suppression: Developers can suppress non-functional risks in bulk—potentially clearing thousands of non-exploitable vulnerabilities with a single click—allowing teams to focus on the 1% of reachable, exploitable risks in their custom layers.
Operationalizing Security with Workflows
Mend.io allows organizations to move beyond simple scanning into automated governance:
SLA & Violation Management: Automatically trigger violations and set remediation deadlines (SLAs) based on vulnerability severity.
Custom Alerts: Configure workflows to receive instant notifications (via email or Jira) whenever a new DHI is added to the environment.
Pipeline Gating: Use Mend’s workflow engine to fail builds only when high-risk, reachable vulnerabilities are introduced in custom code, keeping the CI/CD pipeline moving.
Continuous Patching & AI-Assisted Migration
Automated Synchronization: For Enterprise DHI users, patched base images are automatically mirrored to Docker Hub private repositories. Mend.io verifies these updates, confirming that base-level risks have been mitigated without requiring a manual Pull Request.
Ask Gordon: Leverage Docker’s AI agent to analyze existing Dockerfiles and recommend the most suitable DHI foundation, reducing the friction of migrating legacy applications to a secure environment.
The Mend.io and Docker integration operationalizes this by providing an auditable trail of security declarations, ensuring compliance is a byproduct of the standard development workflow rather than a separate, manual task.
