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

12 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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 · found on this site
  • 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 holds a strong regional market position in the German radio advertising sector, leveraging multiple brands to cover a wide geographic area and diverse audiences. Their competitive advantage lies in combining traditional radio reach with digital and social media advertising. The business targets advertisers seeking broad and localized exposure. Partnership with related radio station domains strengthens their ecosystem. The absence of detailed company registration data on the site limits full transparency but the presence of privacy and imprint pages supports legitimacy. Growth potential exists through digital marketing expansion and event sponsorship offerings.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, GDPR-compliant cookie consent via Usercentrics, and no visible sensitive data exposure. However, the lack of published security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and readiness. No known vulnerabilities or outdated libraries were detected. Security headers appear missing or not reported, which could be enhanced to improve protection against common web attacks. Overall, the security risk is moderate with recommendations to formalize policies and improve header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add and configure essential HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used content management system, combined with modern JavaScript libraries like jQuery and Owl Carousel for interactive elements. The integration of Usercentrics CMP ensures GDPR-compliant cookie management. Hosting is provided by kasserver.com, a German hosting provider, aligning with the site's regional focus. Performance is moderate with video content and multiple scripts, but mobile optimization is good. SEO is supported by proper meta tags and Open Graph data. There is an opportunity to improve technical SEO and accessibility compliance further. No critical technical debt or risks were identified.
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.
