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

Galerie Artlantis is a small non-profit art association based in Bad Homburg, Germany, focused on organizing art exhibitions, cultural events, and promoting local artists. The website serves as a portal for event information, artist presentations, and community engagement. The business operates primarily in the cultural sector with a local/regional market position. Technically, the site is built on WordPress with common plugins such as Slider Revolution and Contact Form 7, indicating a moderate level of digital maturity. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS enabled but lacks advanced security headers and cookie consent mechanisms, which are recommended for GDPR compliance. Overall, the domain registration data aligns well with the website content, supporting legitimacy and trustworthiness.

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

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 association targets art enthusiasts and the local community, offering exhibitions and events that foster cultural participation. Revenue streams likely include memberships, event ticketing, and donations. The website integrates with MailChimp for newsletter distribution, indicating an active marketing approach. Social media channels on Facebook, Instagram, and YouTube support community outreach. The presence of subdomains for specific events suggests a structured event management ecosystem. The business model is typical for non-profit cultural organizations, focusing on community engagement rather than commercial sales.

Security posture

The website uses HTTPS, ensuring encrypted communication. However, the absence of key security headers such as Content-Security-Policy and HSTS reduces protection against certain web attacks. No incident response or vulnerability disclosure information is provided, which could hinder timely security issue reporting. Forms are implemented via Contact Form 7, a widely used plugin, but no explicit anti-spam or input validation details are visible. The site should enhance security by adding recommended headers, implementing cookie consent, and publishing security contact information.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and improve user privacy transparency.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen web security.
  3. Publish an incident response or abuse contact email to facilitate vulnerability reporting and incident management.
  4. Regularly update WordPress core and plugins to mitigate known vulnerabilities.
  5. Consider adding a security.txt file to communicate security policies and contacts clearly.

Technical notes

Notes

The website is built on WordPress 6.1.9 with a modern tech stack including jQuery, Bootstrap, and Slider Revolution for enhanced UI/UX. The site loads moderate resources and is mobile responsive. SEO is basic with meta tags and RSS feed links present. Accessibility features are minimal but present. Hosting provider details are not explicit, but DNS uses UI-DNS name servers. Performance is moderate, with potential improvements in caching and resource optimization. No critical technical debt or deprecated technologies detected.
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.
