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. 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

    • 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

    • High

      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

Art Kaleidoscope positions itself as a niche regional media outlet specializing in art and culture within Frankfurt and the Rhein-Main region. Its competitive advantage lies in detailed local art coverage and partnerships with numerous museums and galleries, as evidenced by extensive external links. The business model likely includes magazine sales, advertising, and digital app engagement. The presence of a mobile app indicates digital maturity and audience engagement efforts. The company appears small-sized with a focused market segment. The lack of explicit business registration or company details limits deeper business intelligence. The partnership ecosystem includes cultural institutions and social media platforms, enhancing reach and credibility.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and a cookie consent mechanism is implemented respecting Do Not Track signals. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces the overall security posture. No vulnerability disclosures or incident response contacts are provided, which could hinder timely security issue management. The use of third-party analytics (etracker) introduces moderate user tracking but is managed with consent. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the site would benefit from enhanced security controls and transparency to improve compliance and trust.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen security posture.
  3. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  4. Include direct company contact details such as official emails and phone numbers to enhance business credibility.
  5. Regularly audit third-party scripts and update CMS and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Weblication CMS, a specialized content management system, and employs standard web technologies including HTML5, CSS, and JavaScript. It integrates etracker for analytics and user tracking with a cookie consent mechanism. The site is mobile-optimized and features a responsive design. Performance is moderate, with no explicit data on hosting provider or CDN usage. SEO is basic with meta description and keywords present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but present. The technical stack is stable but could benefit from modernization and enhanced security configurations.
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.
