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

Hanser Literaturverlage is a reputable German publishing house specializing in literature and books across several imprints including Hanser Kinder- und Jugendbuch, Zsolnay, Hanser Berlin, and hanserblau. The website serves as a comprehensive platform for showcasing their publications and authors, targeting a broad audience interested in literature. Technically, the site is built on a modern Next.js framework with React, hosted likely on Noris Network infrastructure, and integrates accessibility tools and consent management solutions, reflecting a mature digital presence. Security posture is solid with HTTPS enforcement, security headers, and cookie consent mechanisms, though there is room for improvement in publishing explicit security policies and incident response information. Overall, the domain registration and WHOIS data align well with the business claims, indicating legitimacy and trustworthiness.

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

2 findings rated critical or high. Fix these first.

  1. 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

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

Hanser Literaturverlage holds a strong position in the German publishing market with multiple subsidiary imprints. Their business model revolves around traditional and digital book publishing, author promotion, and direct sales. The company targets readers of all ages with a focus on literary works. The website supports marketing and customer engagement through integrated analytics and marketing tools like eTracker and Emarsys. The presence of a comprehensive privacy and cookie policy with consent mechanisms indicates compliance with GDPR and related regulations. The company maintains consistent branding and provides clear contact information, enhancing credibility.

Security posture

The website demonstrates a good security posture with HTTPS enabled and multiple security headers present. The use of cookie consent tools and blocking scripts for tracking technologies shows attention to privacy compliance. However, the absence of a dedicated security policy or vulnerability disclosure page and lack of incident response contact details are gaps that could be addressed to improve transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. The integration of accessibility tools also reflects a commitment to inclusive security and usability.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  3. Add explicit incident response contact information such as security@ or abuse@ email addresses.
  4. Regularly review and audit third-party scripts to minimize potential vulnerabilities.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance information.

Technical notes

Notes

The website is built on a modern React-based Next.js framework, ensuring server-side rendering and good SEO capabilities. Hosting appears to be managed by Noris Network, a reputable German provider. Performance is moderate with multiple CSS and JS assets preloaded and deferred for optimization. Accessibility is enhanced by an integrated DigiAccess tool, and SEO is supported by proper meta tags and Open Graph data. The use of third-party analytics and marketing tools is balanced with consent management. Opportunities exist to further optimize performance and security by minimizing external dependencies and publishing more detailed technical 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.
