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

The Niedersächsische Landesmedienanstalt (NLM) is a regional media regulatory authority in Niedersachsen, Germany, responsible for licensing private radio and television broadcasters and supervising broadcast and telemedia content. The organization also promotes media competence, supports citizen broadcasting, and facilitates the digitalization of broadcasting technology. The website reflects a professional and government-oriented presence with clear communication of its mission and services. The target audience includes broadcasters, media professionals, educators, and the general public interested in media regulation and education. Technically, the website is built on the TYPO3 CMS platform, utilizing modern web technologies such as jQuery and Cookiebot for consent management. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Hosting appears professional with DNS servers linked to vision-connect.de and xlink.net, indicating stable infrastructure. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms with granular user controls. While no explicit security headers were detected in the provided data, no vulnerabilities or exposed sensitive data were found. The absence of a published security or incident response policy is noted as an area for improvement. Overall, the security posture is solid for a public-facing regulatory website. The website is fully accessible without any WAF or security challenge blocking content. Privacy compliance is strong, with a comprehensive privacy policy and cookie consent aligned with GDPR requirements. Contact information is clearly presented, including phone numbers and a physical address, enhancing business credibility. Social media presence on LinkedIn and YouTube further supports trust and outreach. Strategic recommendations include implementing security headers, publishing a security.txt file for vulnerability disclosure, and enhancing incident response transparency. These steps would strengthen the site's security maturity and user trust further.

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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  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

NLM holds a key position as a governmental media regulator in Niedersachsen, focusing on licensing and oversight of private broadcasters and telemedia. Its business model is regulatory and public service oriented, funded likely through public budgets. The organization targets broadcasters, media professionals, educators, and citizens interested in media literacy and compliance. The website content and linked resources indicate active engagement in media competence projects and public outreach. Partnerships with media institutions and educational platforms are evident through external links. The presence of press releases and event announcements suggests ongoing activity and relevance in the regional media landscape. No commercial revenue streams or affiliate programs are evident, consistent with its public authority role.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of reputable third-party services like Cloudflare for bot detection and Cookiebot for consent management. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of explicit security headers such as Content-Security-Policy or X-Frame-Options is a minor gap. No dedicated security or incident response policies are published, which could limit transparency and preparedness. The cookie consent implementation is comprehensive and GDPR compliant, indicating good privacy practices. Overall, the site is secure for its purpose but could benefit from enhanced security policy disclosures and technical header configurations.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to provide a clear vulnerability disclosure channel and improve incident response readiness.
  3. Develop and publish a dedicated security and incident response policy page to increase transparency and user trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance with WCAG standards and broaden user inclusivity.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used open-source content management system, indicating a professional and maintainable infrastructure. The use of jQuery and Cookiebot scripts supports interactive features and compliance with privacy regulations. The site is mobile-optimized with responsive design elements and includes meta tags for viewport and social media cards, supporting SEO and usability. Hosting details suggest stable DNS providers (vision-connect.de and xlink.net). Performance is moderate with compressed CSS and JS assets, though no explicit performance metrics were provided. The site uses standard HTML5 and CSS3 technologies with no deprecated elements detected. Opportunities exist to modernize JavaScript usage and improve accessibility compliance.
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.
