Risk levelLow

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

Thienemann Verlage is a German publishing company specializing in children's and youth literature, offering a broad catalog of books, e-books, and related services. The website is professionally designed, built on TYPO3 CMS, and features modern UI components such as carousels and sliders. The company targets children, youth, parents, and educators with a focus on educational and entertaining content. The site is hosted with Microsoft Online DNS services and uses HTTPS with cookie consent managed by Usercentrics. However, explicit privacy policies, terms of service, and direct contact information are not readily found on the homepage, which could be improved for compliance and user trust. Security posture is good with HTTPS and no visible vulnerabilities, but additional security headers and incident response contacts are recommended.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  4. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 company holds a solid market position in the German children's book publishing sector, with a medium-sized operation and consistent branding. Their business model revolves around publishing and retailing books online, supplemented by events and multimedia content. The website's technical infrastructure leverages TYPO3 CMS and integrates marketing and analytics tools like Google Tag Manager and Usercentrics. The absence of explicit privacy and security policies suggests room for improvement in compliance and transparency. The company appears to maintain professional DNS and hosting arrangements, indicating operational maturity.

Security posture

The website enforces HTTPS and implements cookie consent, indicating awareness of privacy and security best practices. No security.txt or vulnerability disclosure mechanisms are present, and no explicit security policies or incident response contacts are visible. Security headers are not explicitly detected in the HTML content, suggesting potential enhancement areas. No exposed sensitive data or vulnerable libraries were found. Overall, the security posture is good but could be strengthened by publishing security policies, adding security headers, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including emails and phone numbers for general and security incident reporting.
  4. Implement a security.txt file to facilitate vulnerability disclosure.
  5. Enhance transparency around data retention and cookie usage to improve GDPR compliance.

Technical notes

Notes

The website uses TYPO3 CMS, a robust open-source content management system, combined with modern JavaScript libraries like Splide.js for interactive carousels. Hosting appears to be managed via Microsoft Online DNS services, indicating enterprise-grade infrastructure. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with asynchronous loading of scripts such as Google Tag Manager and Usercentrics. No critical technical issues or deprecated technologies were detected. Opportunities exist to improve security headers and formalize privacy and security documentation.
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.
