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

openmediavault is an open source network attached storage (NAS) solution based on Debian Linux, targeting small offices and home offices. It offers a modular framework with services such as SSH, FTP, SMB/CIFS, media servers, RSync, and BitTorrent client, enabling users to easily deploy and manage NAS without deep technical knowledge. The website is professionally maintained with consistent branding and active content updates, reflecting a mature project with a clear focus on its niche market. Technically, the site runs on WordPress with modern plugins and a responsive design, ensuring good user experience and SEO. Security posture is strong with HTTPS, privacy-focused analytics (Matomo), and GDPR-compliant cookie consent mechanisms. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly available, representing areas for improvement. Overall, the domain's WHOIS data is unavailable, likely due to privacy protection, but the website's professionalism and transparency support its legitimacy.

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

4 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 project operates in the technology sector, specifically in open source NAS solutions. Its business model revolves around providing free software with extensibility via plugins, targeting small and home office users. The website's active blog and social media presence indicate ongoing development and community engagement. The absence of direct contact information suggests a community-driven or volunteer-based operation rather than a commercial enterprise. The project leverages partnerships with open source communities and maintains resources such as forums, bug trackers, and documentation to support users. Growth indicators include recent software updates and active content management. Strategic observations suggest focusing on enhancing trust through published security policies and clearer contact channels.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, privacy-respecting analytics, and a comprehensive cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure processes indicates gaps in formal security governance. Compliance with GDPR is evident through the cookie banner and privacy policy. The site would benefit from adding security.txt and explicit incident response information to improve transparency and readiness. Overall, the security posture is solid but could be enhanced by formalizing policies and communication channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Add HTTP security headers like Content-Security-Policy and X-Content-Type-Options to enhance protection.
  5. Consider publishing terms of service to clarify user rights and responsibilities.

Technical notes

Notes

The website is built on a stable and widely used CMS platform, WordPress, with a modern responsive theme (GeneratePress) and plugins supporting GDPR compliance and enhanced user experience. The tech stack includes Debian Linux as the backend OS for the software product itself, and JavaScript libraries such as jQuery and Matomo for analytics. Performance is moderate with good mobile optimization and accessibility features. The site uses HTTPS with a presumably strong SSL configuration. There is no indication of technical debt or outdated components in the provided HTML. Opportunities exist to improve security headers and formalize security-related documentation to reduce technical risks.
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.
