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

Sandstein Kultur is a specialized agency and publishing house based in Dresden, Germany, focusing on cultural and art-related publications such as exhibition catalogs and museum catalogs. The company targets cultural institutions, museums, and art enthusiasts, offering both publishing and agency services including campaigns and promotional materials. The website reflects a niche market position within the German cultural media sector, supported by a professional and consistent brand presentation. Technically, the website is built on Craft CMS and uses modern web technologies including SVG graphics and Matomo analytics with cookies disabled, indicating a moderate level of digital maturity and privacy awareness. Hosting is provided by SchlundTech, a reputable German hosting provider. The site is mobile-optimized and accessible, with good SEO practices. From a security perspective, the site enforces HTTPS and uses CSRF tokens for form submissions, but lacks explicit security headers and a published security policy or incident response information. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is supported by a clear privacy policy and terms of service, though a cookie consent mechanism is missing. Overall, the website is safe, professional, and trustworthy with a good balance of content quality and technical implementation. Strategic improvements in security headers, cookie consent, and incident response transparency would enhance the security posture and compliance further.

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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Sandstein Kultur operates in the cultural media and publishing sector, serving a specialized market of museums, cultural institutions, and art consumers. Its business model combines publishing with agency services, providing a comprehensive offering from campaigns to catalogs. The company maintains a strong social media presence across Instagram, Facebook, LinkedIn, YouTube, and Spotify, indicating active engagement with its audience. The website's content and structure suggest a small-sized enterprise with a focused niche. No parent or subsidiary companies were identified. The company leverages a reputable German hosting provider and modern CMS technology, supporting stable operations and digital presence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and CSRF protection in place for forms. The use of Matomo analytics with disabled cookies reflects privacy-conscious tracking. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth. No explicit security policy or incident response contact information is published, which may hinder rapid response to security incidents. There is no vulnerability disclosure policy or security.txt file, limiting transparency for security researchers. Overall, the site is secure for typical use but could benefit from enhanced security controls and transparency to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply with EU cookie laws and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and readiness for security events.
  4. Consider establishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly review and update privacy and security practices to maintain compliance with GDPR and emerging regulations.

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.
