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

    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 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

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 Neue Medien GmbH operates primarily as a service provider in the technology sector, focusing on digital solutions for businesses and public institutions in Germany. Their competitive advantage lies in their extensive experience, comprehensive service offerings, and strong focus on accessibility and usability. The company targets organizations requiring professional web and software development services, including government agencies and cultural institutions. Their business model is service-oriented, generating revenue through project-based contracts and ongoing support. The partnership with Sandstein Kultur indicates a broader ecosystem under the Sandstein brand. Growth indicators include a diverse portfolio of high-profile clients and continuous content updates. The company maintains a professional online presence with clear contact information and social media engagement, supporting credibility and client acquisition.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and the use of anti-spam measures such as Friendly-Challenge captcha. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. There is no publicly available security policy or incident response contact, which could be a gap in transparency and readiness. GDPR compliance is evident through the presence of a comprehensive privacy policy and cookie policy, though a cookie consent mechanism is not implemented. Overall, the security maturity is good but could be enhanced by adopting additional best practices and publishing security documentation.

Recommendations

  1. Implement and enforce security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact information to improve transparency and preparedness.
  3. Introduce a cookie consent mechanism to align fully with GDPR requirements and enhance user privacy control.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built using modern web standards with HTML5, CSS, and JavaScript. It leverages Matomo for analytics, which is a privacy-friendly alternative to Google Analytics. The presence of Friendly-Challenge captcha indicates proactive spam prevention. The site is likely powered by TYPO3 CMS, inferred from script titles and references, which is a robust enterprise CMS. Hosting is provided by Schlundtech, a reputable German hosting provider. The site is mobile-optimized with responsive design and accessibility features such as sign language and easy language options, indicating a strong commitment to inclusive design. Performance is moderate, with lazy loading of images and video content to optimize load times. Overall, the technical infrastructure is solid, with opportunities to improve security headers and cookie consent implementation.
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.
