Risk levelMedium

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

The website is an official microsite for the Gutenberg-Museum hosted under the city of Mainz's domain, representing a government cultural institution dedicated to the history of printing and Johannes Gutenberg. It offers museum exhibitions, a shop, and educational experiences, targeting a broad audience including tourists and culture enthusiasts. The site is professionally designed with good content quality and consistent branding, supporting both German and English languages. Technically, it uses a Sitepark CMS platform with a mix of legacy and modern JavaScript libraries, and is mobile optimized with accessibility features. Security posture is adequate with HTTPS and consent-based Matomo analytics, but lacks explicit privacy, cookie, and security policies on this page. WHOIS data confirms legitimacy and consistency with the official city domain. Overall, the site is trustworthy and well-positioned as a government cultural resource, though it could improve privacy disclosures and security headers.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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"

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 Gutenberg-Museum operates as a government cultural institution under the Landeshauptstadt Mainz, focusing on historical and educational services related to printing history. Its market position is strong regionally with international recognition due to the Gutenberg legacy. The business model centers on museum visits, retail sales, and educational programming. The website supports this with clear content and navigation but lacks direct contact or transactional features on this splash page. The museum benefits from city backing, enhancing credibility and stability. No commercial or affiliate partnerships are evident on this page. Growth potential lies in expanding digital presence and improving privacy and security transparency.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Matomo analytics requiring user consent, indicating privacy awareness. However, the absence of visible security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No vulnerability disclosures or incident response contacts are provided, limiting transparency for security issues. The use of an older jQuery version could pose risks if not patched. No exposed sensitive data or suspicious scripts were detected. Overall, the site is secure for general public use but would benefit from enhanced security headers, published policies, and a vulnerability disclosure mechanism to improve trust and compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Create and publish a security.txt file or vulnerability disclosure page with contact information for security incidents.
  4. Update JavaScript libraries to current versions to mitigate potential vulnerabilities.
  5. Provide clear contact information including emails and phone numbers for general and security-related inquiries to improve transparency.

Technical notes

Notes

The website is built on the Sitepark Information Enterprise Server CMS platform, utilizing a combination of legacy jQuery 1.11.2 and modern JavaScript libraries such as Modernizr and Leaflet.js for interactive maps. It integrates Matomo analytics with consent enforcement and ReadSpeaker for accessibility. The site is mobile optimized with responsive breakpoints and accessibility features like skip links and ARIA roles. Performance is moderate, with multiple CSS and JS files loaded asynchronously. No major technical debt is evident, but updating legacy libraries and adding security headers would modernize the infrastructure. Hosting details are not explicit but the domain and name servers indicate official city infrastructure. SEO is supported by proper meta tags and Open Graph data. Overall, the technical implementation is solid but could be improved in security and privacy transparency.
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.
