0–100, higher is better. How it is calculated

k0smotron.io is a professionally designed website representing an open source Kubernetes operator project focused on managing k0s control planes and clusters. The project is affiliated with Mirantis, a recognized company in the cloud native and Kubernetes ecosystem. The website provides comprehensive technical content, documentation links, and community resources targeting Kubernetes operators and enterprises managing multi-cluster environments. Technically, the site is hosted on GitHub Pages, uses modern web technologies including Bootstrap and FontAwesome, and integrates privacy-respecting analytics via Plausible. Security posture is adequate with HTTPS and OCSP stapling enabled, but lacks some best practices such as HSTS and explicit security policies. Privacy compliance is good with a comprehensive privacy policy linked from Mirantis, though no cookie consent mechanism is present. Overall, the site is trustworthy, professional, and well-aligned with its business purpose.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

6 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business behind k0smotron.io is Mirantis, which provides enterprise Kubernetes solutions and open source projects. k0smotron targets Kubernetes cluster operators needing scalable multi-cluster management and edge computing solutions. The project leverages the Cluster API and k0s Kubernetes distribution to offer flexible control plane lifecycle management. The business model includes open source software with enterprise support and services. The website ecosystem includes related projects and community forums, indicating a healthy partnership and community engagement. The market positioning is niche but important within Kubernetes lifecycle management. No direct revenue streams or contact details are published on the site, consistent with an open source project model supported by Mirantis.

Security posture

The website demonstrates a moderate to good security posture. HTTPS is enforced with TLS 1.2 and 1.3 support and OCSP stapling enabled, ensuring encrypted and validated connections. However, the absence of HSTS headers reduces protection against protocol downgrade attacks. No security.txt or vulnerability disclosure policy is published, and no incident response contacts are provided, which limits transparency for security issues. The site does not expose sensitive data or use vulnerable libraries. Privacy compliance is good but could be improved with cookie consent mechanisms. Overall, the security posture is sufficient for an informational open source project site but could be enhanced to meet enterprise-grade standards.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to improve HTTPS enforcement.
  2. Implement a cookie policy and consent mechanism to comply with privacy regulations and improve user transparency.
  3. Publish a security policy and incident response contact information or security.txt file to enhance trust and facilitate vulnerability reporting.
  4. Regularly review and update third-party scripts and dependencies to avoid introducing vulnerabilities.
  5. Consider adding direct contact information or support channels to improve user engagement and trust.
Technical notes

Notes

The website is hosted on GitHub Pages, leveraging a static site architecture with Bootstrap for responsive design and FontAwesome for icons. It uses Google Fonts for typography and Plausible Analytics for privacy-focused visitor tracking. The site loads quickly with minimal resources and is mobile optimized. SEO is supported by proper meta tags and Open Graph image tags. No CMS is detected, indicating a custom or static site generator approach. DNS is managed via AWS Route 53 with multiple A records for redundancy. SSL configuration supports modern TLS versions with OCSP stapling but lacks HSTS. Overall, the technical implementation is modern, performant, and well-maintained with room for security enhancements.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
