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

The Document Foundation operates LibreOffice, a leading free and open source office suite that serves a broad audience including individual users, businesses, and the open source community. The website reflects a mature, well-established project with a strong community focus and non-profit backing. Key services include software distribution, community support, professional support, and extensive documentation. The project positions itself as a successor to OpenOffice with compatibility for Microsoft Office formats. Technically, the website is built on the SilverStripe CMS platform, utilizing modern frontend frameworks such as Bootstrap and Font Awesome, with privacy-conscious analytics via Piwik/Matomo. The site is mobile optimized and well-structured, though some accessibility features could be improved. Performance is moderate with room for optimization. Security posture is generally good with HTTPS usage and no visible sensitive data exposure. However, the absence of explicit security headers and cookie consent mechanisms are areas for improvement. The WHOIS data is unavailable, likely due to privacy protection, which is common for open source projects but limits domain trust verification. Overall, the website is professional, trustworthy, and well-aligned with the organization's mission. Strategic recommendations include enhancing security headers, implementing cookie consent for GDPR compliance, publishing vulnerability disclosure policies, and improving accessibility and performance.

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

5 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
  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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 21 days

      What to do: Renew domain registration before expiration

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email 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

LibreOffice is positioned as a major open source office suite alternative, supported by The Document Foundation, a non-profit entity. Its business model relies on community contributions, professional support offerings, and partnerships. The project benefits from a strong ecosystem including conferences, documentation, and localization efforts. Market positioning is strong within the open source and free software communities, with a clear focus on compatibility and user empowerment. Growth indicators include regular releases and active community engagement. Partnerships with related domains and social media presence reinforce its ecosystem.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML content. The use of Piwik/Matomo analytics with disabled cookies indicates privacy awareness. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerability disclosure or incident response contacts are published, which could hinder timely security communication. GDPR compliance is partially evidenced by a comprehensive privacy policy but lacks cookie consent mechanisms. Incident response readiness and security culture indicators are not explicitly visible.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a clear vulnerability disclosure policy and incident response contact information to improve security transparency and responsiveness.
  4. Enhance website accessibility features to meet WCAG standards and improve user inclusivity.
  5. Optimize website performance through resource minification, caching strategies, and image optimization to improve user experience.

Technical notes

Notes

The website uses a modern technology stack with SilverStripe CMS, Bootstrap framework, Font Awesome icons, and jQuery for interactivity. Analytics are handled via Piwik/Matomo with cookie tracking disabled, reflecting privacy-conscious design. The site is mobile responsive and well-structured with clear navigation. However, no hosting provider information is directly available. Performance is moderate, with potential improvements in loading speed and accessibility. No outdated or vulnerable libraries were detected in the provided scripts. The site lacks visible security headers which is a technical risk. Overall, the infrastructure supports a professional and community-driven open source project.
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.
