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

The website hr4.de is the official online presence of hr4, a radio station operated by Hessischer Rundfunk, a major public broadcaster in Germany. It targets the 50+ generation with positive lifestyle content, music, and community engagement. The site offers rich multimedia content including radio streaming, podcasts, recipes, and event information, reflecting a mature and well-established media entity. The branding and structured data confirm its authenticity and regional focus on Hessen, Germany. Technically, the site uses modern web technologies such as Alpine.js, Piano Analytics, and ARD Player, hosted on professional infrastructure with secure HTTPS connections and some security headers. However, explicit privacy and cookie policies are not detected in the provided content, which is a compliance gap. No security policy or incident response information is available, limiting transparency in security posture. Overall, the site is professionally designed, user-friendly, and trustworthy, but could improve privacy compliance and security disclosures.

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

6 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

    • 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

Hessischer Rundfunk's hr4.de serves as a regional public media platform focusing on radio broadcasting and digital content for older adults. The business model is public service broadcasting with revenue likely from public funds and advertising. The site integrates with sister stations and partner media sites, enhancing its ecosystem. The content strategy emphasizes community involvement, lifestyle, and entertainment, positioning hr4 as a trusted regional media brand. The use of advanced analytics and modern web frameworks indicates a commitment to digital maturity. However, the absence of explicit privacy and security policies suggests areas for operational improvement. The site’s external links to related public media and partner domains reinforce its networked presence in the German public broadcasting sector.

Security posture

The website demonstrates a good security baseline with HTTPS enforcement and a Content-Security-Policy header restricting image sources. The use of modern JavaScript polyfills and analytics scripts is well managed. However, the CSP is limited to images only, lacking restrictions on scripts and other resources, which could be enhanced. No security.txt or vulnerability disclosure page is found, and no incident response contacts are provided, which reduces transparency and readiness perception. No exposed sensitive data or vulnerable libraries are detected in the HTML content. Overall, the security posture is solid but could be improved by adopting additional security headers, publishing security policies, and providing clear incident response channels.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement a full Content-Security-Policy including script-src, style-src, and other directives to harden security.
  3. Add security headers such as Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  4. Provide a public security policy or vulnerability disclosure page and incident response contact information.
  5. Enhance transparency on data collection, retention, and user privacy to improve trust and compliance.

Technical notes

Notes

The website is built on a custom CMS (hrcms) version 4.26.0, leveraging modern frontend technologies including Alpine.js for interactivity, Modernizr for feature detection, and Piano Analytics for user behavior tracking. Media playback is handled by Clappr and ARD Player components, supporting adaptive streaming. The site is optimized for mobile devices with responsive design and accessibility considerations. DNS is managed via sec-provider.de nameservers, indicating professional hosting. Performance is moderate with preloading of critical assets and deferred script loading. SEO is supported by comprehensive meta tags, Open Graph, Twitter Cards, and JSON-LD structured data. The technical stack is modern and well-maintained, though some security header enhancements and privacy compliance improvements are recommended.
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.
