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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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';…

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 business operates in the government and non-profit cultural sector, offering a subscription-based model for museum access and cultural event participation. It holds a strong market position with 25 years of history and official backing by the city of Frankfurt. Revenue streams come from card sales (single, family, gift cards) and associated cultural magazine subscriptions. The target audience includes local residents, families, tourists, and culture lovers. The partnership ecosystem includes official Museumsufer Frankfurt sites and cultural institutions. The business model emphasizes cultural engagement and community participation, supported by digital marketing and social media presence. Growth indicators include anniversary promotions and interactive campaigns like GeoCaching. The company maintains a consistent brand and trust signals through official affiliations.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. It uses a reputable consent management platform (Usercentrics) to comply with GDPR. Tracking technologies are implemented with user consent. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerability disclosures or security.txt files were found. The site does not expose forms with sensitive inputs beyond basic contact and purchase forms. Overall, the security risk is low, but enhancing header policies and incident response transparency would strengthen the posture.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider adding a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website uses a clean HTML5 and CSS3 structure with modern JavaScript libraries such as Swiper.js for interactive elements. Google Tag Manager and Facebook Pixel are integrated for analytics and marketing, controlled via Usercentrics CMP for consent compliance. The site is mobile optimized with responsive navigation and good performance. No CMS is detected, indicating a custom or static site approach. Hosting details are not explicit but domain name servers suggest a professional hosting environment. The site could benefit from improved accessibility features and enhanced security headers. Overall, the technical implementation is solid with room for modernization in security and accessibility.
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.
