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

Klassik Radio holds a strong market position in the German classical music streaming niche, providing multiple services including live concerts and premium streaming. The business model revolves around free and subscription-based streaming, supported by advertising and partnerships with ticketing and streaming platforms. The company targets a broad demographic of classical music listeners and cultural consumers. Partnerships with select.klassikradio.de and tickets.klassikradio.de enhance service offerings. The website's content and branding are consistent, supporting a medium-sized enterprise profile in the media industry.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and cookie consent management via Usercentrics. However, it lacks published security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and trust. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of security headers and explicit security documentation suggests room for improvement in security best practices and compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages linked prominently on the website.
  2. Implement and disclose a formal security policy and incident response procedures.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including emails and phone numbers for customer and security inquiries.
  5. Consider publishing a security.txt file or vulnerability disclosure policy to encourage responsible reporting.

Technical notes

Notes

The website is built on a modern tech stack including Next.js and React, ensuring good performance and mobile responsiveness. Use of Usercentrics CMP for cookie management and Google Tag Manager for analytics indicates a mature digital marketing setup. Hosting details are not explicit but domaincontrol.com nameservers suggest GoDaddy or similar provider. The site loads efficiently with preloading and deferred scripts. No CMS detected explicitly, possibly a custom or headless setup. Technical risks are minimal but could be reduced further by adding security headers and improving 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.
