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

The website gutenberg.de is an official cultural microsite dedicated to Johannes Gutenberg, hosted under the Landeshauptstadt Mainz domain. It serves as an educational and informational platform providing historical content about Gutenberg's life, his invention of movable type printing, and related cultural institutions such as the Gutenberg Museum. The site targets a general audience interested in history and culture, with a focus on accessibility and multilingual support. The business model is non-commercial, focusing on public cultural outreach and education. Technically, the site is built on the Sitepark Information Enterprise Server CMS with a technology stack including jQuery, Modernizr, and Matomo analytics for privacy-conscious user tracking. The site is mobile-optimized, accessible, and performs moderately well. It uses HTTPS and a cookie consent banner, demonstrating good privacy compliance. However, explicit security headers and incident response information are not present. From a security perspective, the site shows good practices such as HTTPS enforcement and no visible vulnerabilities or exposed sensitive data. The use of Matomo analytics aligns with GDPR compliance. The absence of explicit security policies or contact points for incident response is a minor gap. Overall, the domain registration and WHOIS data are consistent with a legitimate government cultural site, supporting a high trust level. The overall risk is low, with recommendations to enhance security headers, provide explicit security policies, and keep libraries updated. The site is safe, professional, and trustworthy, serving its cultural and educational mission effectively.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  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

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 site represents a government cultural initiative by the city of Mainz, focusing on promoting the legacy of Johannes Gutenberg. It holds a strong market position as an authoritative source for historical and cultural information related to Gutenberg and Mainz. The business model is informational and non-commercial, relying on public funding and partnerships with cultural institutions such as the Gutenberg Museum and related foundations. The target audience includes historians, educators, tourists, and the general public interested in cultural heritage. The partnership ecosystem includes several official Gutenberg-related organizations, enhancing credibility and reach. Growth indicators include upcoming events like the 625th Gutenberg anniversary in 2025. The site’s operations emphasize accessibility, multilingual support, and digital engagement through multimedia content.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no visible security vulnerabilities in the provided HTML content. The use of a cookie consent banner and Matomo analytics indicates attention to privacy compliance. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies are areas for improvement. No contact channels for security incidents or abuse reports are provided, which could hinder timely incident response. The site does not expose sensitive data or use outdated vulnerable libraries based on the scripts detected. Overall, the security posture is good but could be enhanced by adopting additional security headers and publishing clear security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and readiness.
  3. Regularly update JavaScript libraries and dependencies to mitigate risks from known vulnerabilities.
  4. Enhance user trust by including more explicit business contact information such as emails or phone numbers for support and inquiries.
  5. Continue to maintain and improve accessibility and privacy compliance features to align with evolving regulations and user expectations.

Technical notes

Notes

The website is built on a custom CMS platform (Sitepark Information Enterprise Server) with a technology stack including jQuery 1.11.2, Modernizr, and Matomo analytics. The site uses asynchronous loading for analytics and includes accessibility features such as ARIA roles and skip links. The design is responsive with breakpoints for mobile navigation. Performance is moderate, with multiple JavaScript libraries loaded but no heavy frameworks detected. SEO is supported by meta tags and Open Graph properties. The site uses a cookie consent banner for GDPR compliance. Hosting details are not explicit but likely managed by the city of Mainz or an associated provider. There is no evidence of technical debt or deprecated technologies beyond the somewhat older jQuery version. Overall, the technical infrastructure is stable and suitable for the site’s informational purpose.
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.
