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

Antenne Schlager is a German media company specializing in schlager music broadcasting via DAB+ and web radio. It operates under the parent company Antenne Niedersachsen GmbH & Co. KG, targeting schlager music fans with a curated selection of popular and cult hits. The website demonstrates a moderate level of digital maturity, employing modern web technologies such as Angular, Usercentrics for cookie consent, Google Tag Manager, and Microsoft Clarity for analytics. The site is mobile optimized and provides a good user experience with consistent branding and relevant content. Security posture is adequate with HTTPS enforced and cookie consent mechanisms in place, but lacks explicit security headers and formal privacy and terms of service documentation. Overall, the domain registration is consistent 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

5 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"

  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

The company positions itself as a niche media broadcaster within the German schlager music market, leveraging both traditional and digital platforms to reach its audience. Its business model revolves around content broadcasting and online streaming, supported by advertising and marketing tools integrated into the website. The lack of explicit contact information and formal policies suggests room for improvement in transparency and customer engagement. The use of recognized analytics and consent management tools indicates awareness of regulatory requirements and user privacy concerns. The company benefits from association with a larger parent entity, enhancing its market credibility.

Security posture

The website employs HTTPS and integrates cookie consent management, reflecting compliance with basic security and privacy standards. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth posture. No vulnerability disclosures or incident response contacts are provided, which could hinder timely security communication. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Overall, the security maturity is moderate but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including security incident response and data protection officer contacts.
  4. Consider publishing a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve transparency.

Technical notes

Notes

The website is built using Angular framework, leveraging modern web fonts and responsive design techniques for good mobile optimization. It integrates third-party services such as Usercentrics for cookie consent, Google Tag Manager for analytics, and Microsoft Clarity for user behavior tracking. The site uses HTTPS with good SSL configuration. Performance is moderate, with no major issues detected in the HTML structure or meta tags. Accessibility features are basic but present. SEO optimization is good with appropriate meta descriptions and Open Graph tags. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure supports a professional media website but could benefit from enhanced security configurations and more transparent business information.
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.
