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

TVZ Theologischer Verlag Zürich AG is a specialized Swiss theological publisher offering a wide range of academic and church-related books and materials. The website presents a professional and comprehensive catalog targeting theologians, students, clergy, and readers interested in religious studies and spirituality. The business model focuses on publishing and selling both print and digital editions, with a strong emphasis on quality and educational content. The company maintains a consistent brand presence and leverages partnerships with payment processors and content providers to enhance user experience. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Fonts, and PayPal Plus for payments. It integrates a cookie consent manager to comply with privacy regulations and features a responsive design optimized for mobile devices. While the site performs moderately well, there is room for improvement in accessibility and security headers implementation. From a security perspective, the site enforces HTTPS and uses a cookie consent mechanism with opt-out options, indicating good privacy compliance. However, it lacks explicit security policies, incident response contacts, and security.txt files. No vulnerabilities or exposed sensitive data were detected, and the WHOIS data aligns well with the website's claims, supporting legitimacy. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR requirements. Strategic improvements in security headers and incident response transparency would further strengthen its security posture and user trust.

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

3 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. 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

TVZ holds a niche market position as a theological publisher in Switzerland, catering to academic and religious communities. Its competitive advantage lies in specialized content, including editions of the Zürcher Bibel and related theological works. Revenue streams primarily come from book sales, both physical and digital. The target customers include clergy, theology students, and religious educators. The company demonstrates growth potential through upcoming publications and active engagement in cultural and religious events. Partnerships with payment providers and media outlets enhance its ecosystem. The website's detailed categorization and content depth reflect a mature operation focused on quality and customer engagement.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a robust cookie consent mechanism. No critical vulnerabilities or exposed sensitive data were found. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. There is no visible incident response or security contact information, which could delay response to security incidents. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security maturity is good but could be enhanced by implementing recommended headers and formalizing incident response channels.

Recommendations

  1. Implement security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a modern and clean technology stack with HTML5, CSS3, and JavaScript. It integrates Google Fonts for typography and PayPal Plus for payment processing. The cookie consent manager is a third-party solution from Wirth & Horn, indicating a focus on compliance. The site is mobile responsive with good navigation clarity and professional design. Performance is moderate, with potential optimization in image loading and script management. No explicit CMS was detected, suggesting a custom or proprietary system. Technical risks are low but could be further reduced by adopting security headers and improving accessibility compliance.
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.
