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

utb is a well-established academic publisher specializing in textbooks for higher education across humanities, social sciences, natural sciences, and economics. The company targets students and educators primarily in German-speaking countries, offering both print and digital educational materials. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content relevant to its audience. Technically, the site employs modern JavaScript libraries, cookie consent management, and analytics tools, hosted likely behind Cloudflare infrastructure, ensuring good performance and security. Security posture is solid with HTTPS enforced and secure user interaction forms, though explicit security policies and incident response information are not publicly disclosed. Overall, the site demonstrates strong compliance with GDPR and privacy standards, with a cookie consent mechanism and detailed privacy policy in German. The absence of exposed sensitive data and the presence of social media links enhance trustworthiness. The WHOIS data shows standard registrar usage without privacy protection, consistent with a legitimate business. Recommendations include updating legacy libraries and publishing explicit security policies to further enhance trust and compliance.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

utb holds a strong market position as a specialized academic publisher with over 50 years of history. Its business model focuses on textbook publishing and digital supplementary materials, serving universities, students, and educators. The company leverages partnerships with libraries and digital platforms like the utb Elibrary. The website's integration of marketing tools like Stamped.io and consent management indicates a focus on customer engagement and compliance. Social media presence across Instagram, LinkedIn, Facebook, and Bluesky supports community building and brand awareness. The lack of visible direct contact emails or phone numbers suggests a controlled communication channel primarily via web forms and dedicated contact pages. The company appears medium-sized with consistent branding and high-quality content, positioning it well in the education sector.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms aligned with GDPR requirements, indicating a mature privacy and security approach. The login and registration forms include UX features like password visibility toggling, enhancing user security. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the use of an outdated jQuery version (1.11.0) could pose security risks if not regularly patched. Security headers are implied but not explicitly confirmed in the HTML. The absence of published security policies or incident response contacts limits transparency in security governance. Overall, the security posture is good but could be improved by updating libraries, explicitly publishing security policies, and confirming security headers.

Recommendations

  1. Update jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Publish explicit security and incident response policies on the website to enhance transparency and trust.
  3. Confirm and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear company contact emails and phone numbers for support and security incident reporting.
  5. Continue to maintain and improve GDPR compliance and cookie consent mechanisms.

Technical notes

Notes

The website uses a combination of legacy and modern JavaScript libraries including jQuery 1.11.0, Owl Carousel for slideshows, Litepicker for date selection, and Stamped.io for reviews. Cookie consent is managed via Consentmanager scripts. Hosting appears to be behind Cloudflare, providing performance and security benefits. The site is mobile optimized with responsive design and accessibility features. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data for search engines. The CMS is not explicitly identified but appears custom or proprietary. Performance is moderate with asynchronous loading of scripts and lazy loading of images. Technical debt is indicated by the use of older jQuery versions. Overall, the technical infrastructure supports a professional and user-friendly experience with room for modernization.
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.
