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

9 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Holzmann Medien holds a strong market position as one of Germany's top 50 economic and specialist publishers. Its competitive advantage lies in its long history, family ownership, and diversified media offerings across multiple industry verticals. The business model combines traditional print media with digital transformation, including audio, video, and events, targeting entrepreneurs and professionals in niche sectors. The company maintains a robust brand portfolio and leverages partnerships through its online shop and multiple portals. Growth indicators include active career offerings and continuous innovation messaging. The partnership ecosystem includes related domains for product sales and specialized portals. Strategic observations highlight a focus on quality content, industry expertise, and digital maturity.

Security posture

The website demonstrates a good security maturity level with HTTPS enabled and use of a reputable consent management platform (Usercentrics). No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in security governance. The site lacks some recommended security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. Compliance with GDPR is evident, but incident response readiness and transparency could be strengthened. Overall, the security posture is solid but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting and enhance trust.
  4. Regularly audit and update all plugins and themes to minimize risk from outdated or vulnerable components.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform utilizing modern technologies such as Bootstrap for responsive design, jQuery for interactivity, and Elementor for page building. It integrates advanced plugins including Yoast SEO for search optimization, Usercentrics for consent management, and Ajax Search Lite for enhanced search functionality. The hosting environment is likely provided by Deutsche Telekom, inferred from DNS name servers. Performance is moderate with room for optimization, especially in lazy loading and caching strategies. The site is mobile optimized and SEO friendly with proper meta tags and structured data (JSON-LD). Technical risks are minimal but include potential outdated plugin versions and missing security headers. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
