Minimus vs Docker Hardened Images

Docker Hardened Images (free tier) are a practical choice for small teams and organizations that want curated images at no cost and are comfortable owning patching, compliance mapping, and governance internally. They improve on public images, but they do not include enterprise SLAs, built-in FIPS or STIG options in the free tier, detailed compliance alignment, or lifecycle-level supply chain controls.

Minimus provides:
  • Minimal, distroless images with 97%+ CVE reduction
  • Enterprise-backed update commitments and predictable patch cadence
  • Built-in CIS and NIST alignment with FIPS-ready options
  • Detailed, version-by-version changelogs for audit transparency
  • Private image customization with governance controls
  • Integrated RBAC and end-to-end supply chain visibility

Docker Hardened Images

Minimus

Why it Matters

Base Architecture

Built on Alpine or Debian. You inherit a full OS.
Minimal and distroless foundations.
A full OS brings along hundreds of packages you did not ask for. Each one is another potential CVE, another scan result, another patch cycle. Over time, your team spends more effort maintaining the image than securing the application.

Minimus images include only what your application needs. Fewer binaries mean fewer CVEs, cleaner scan results, and less noise to triage. Your team focuses on real risk, not background noise.

CVE Reduction

Improved compared to public images.
97%+ CVE reduction compared to public equivalents.
Instead of drowning in low-priority findings, you start with dramatically fewer vulnerabilities. Releases move faster, tickets drop, and security reviews become simpler because most risk was removed before the build finished.

SLA & Update Commitments

No SLA or formal update commitments.
Daily rebuilds and a 48-hour SLA for critical and high severity fixes.
When a critical CVE hits, you know exactly when an updated image will land. No scrambling, no guessing, no internal blame cycle. Just a clear path to remediation you can communicate to stakeholders and auditors.

FIPS 140-3 and STIG

Not available in the free tier.
FIPS 140-3 compliant images and STIG compliant images available.
In regulated industries, compliance gaps delay deals and deployments. Without built-in FIPS or STIG alignment, teams build custom variants and carry the risk themselves. Integrated options remove that burden and accelerate approvals.

CIS and NIST Hardening

Security-focused, but not built around formal compliance frameworks.
Aligned with CIS and NIST benchmarks checks at both the container and application layer
Audits stop being reactive exercises. You begin from an image already aligned to recognized standards, which shortens audit cycles and reduces back-and-forth across security and compliance teams.

Changelogs and Audit

Limited visibility into granular image changes.
Version-by-version detailed changelogs.
When a vulnerability appears or an update ships, you can immediately trace what was added, removed, or modified. No manually inspecting layers, no reverse-engineering builds. Just precise change visibility that accelerates investigations and shortens security review cycles.

Custom Image Creation

Limited built-in customization workflows.
Full Private Image Creator platform with creation-as-code options
Customization typically requires rebuilding images manually or maintaining separate Dockerfiles, with limited guardrails or centralized governance. As environments grow, that approach increases drift, inconsistencies, and long-term maintenance overhead.

With Minimus, teams extend images without rebuilding from scratch. That keeps environments consistent, reduces drift, and preserves security posture even as customization grows.
