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

openSUSE.org is the official website for the openSUSE Linux distribution project, sponsored by SUSE LLC. The site offers detailed information about their Linux distributions including Tumbleweed (rolling release), Leap (regular release), and MicroOS, targeting sysadmins, developers, and desktop users. The project emphasizes community contributions and provides several open-source tools such as Open Build Service, openQA, YaST, and Kiwi. The website is professionally designed with clear navigation and mobile optimization, reflecting a mature digital presence. Technically, the site uses modern web technologies including Bootstrap, FontAwesome, and Matomo analytics for user tracking. The site is served over HTTPS with good SSL configuration, though explicit security headers are not detected. The website lacks explicit privacy and cookie policies, which impacts privacy compliance scores. No forms collecting personal data are present on the main page, reducing immediate privacy risks. From a security perspective, the site shows good practices such as HTTPS enforcement and no visible vulnerabilities or exposed sensitive data. However, the absence of security headers, vulnerability disclosure policies, and incident response contacts are areas for improvement. The WHOIS data is incomplete and malformed, limiting domain trust analysis, but the strong association with SUSE LLC and consistent branding support legitimacy. Overall, openSUSE.org is a trustworthy and professional open-source project website with excellent content quality and business credibility. Strategic improvements in privacy compliance and security policy transparency would enhance its security posture and user trust.

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

8 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

openSUSE operates as an important entity within the technology sector, focusing on Linux distributions and open-source software tools. Its business model is community-driven with sponsorship from SUSE LLC, leveraging donations and hardware contributions. The project targets a global audience of Linux users, developers, and system administrators. It maintains a strong partnership ecosystem with related open-source projects and tools. The website content and social media presence indicate active community engagement and a well-established market position. Growth indicators include recent news updates, conference participation, and new tool releases. The project benefits from SUSE's corporate backing, enhancing its credibility and resource availability.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the lack of security headers such as Content-Security-Policy and absence of explicit security or incident response policies indicate gaps in security best practices. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. Privacy compliance is weak due to missing privacy and cookie policies. The site uses Matomo analytics, which is privacy-focused but still involves user tracking. Overall, the security posture is adequate for an open-source community site but could be improved to meet higher compliance and transparency standards.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting and improve security transparency.
  4. Provide clear incident response contact information, including dedicated security or abuse email addresses.
  5. Enhance accessibility features and conduct regular security audits to maintain a strong security posture.

Technical notes

Notes

The website is built using modern frontend technologies including Bootstrap for responsive design and FontAwesome for icons. It uses Matomo analytics for tracking, which is a privacy-respecting alternative to Google Analytics. The site loads external resources from trusted domains related to the openSUSE project. Performance is moderate with asynchronous loading of analytics scripts. The site is mobile optimized and has good SEO metadata including Open Graph tags for social media sharing. No CMS was detected, suggesting a custom or static site build. Hosting provider details are not available from the provided data. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and privacy features.
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.
