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

The Breitbandzentrum Niedersachsen und Bremen website serves as a central advisory and information hub for broadband and mobile network expansion in the German regions of Niedersachsen and Bremen. It targets municipalities, businesses, and citizens, providing expert guidance on planning, implementation, and funding of digital infrastructure projects. The site is professionally designed, leveraging TYPO3 CMS and SEO tools, and offers comprehensive content relevant to its public service mission. Technically, the site is hosted by webhosting-franken.de, uses HTTPS, and includes cookie consent mechanisms, reflecting a moderate to good digital maturity level. Security posture is adequate with HTTPS and no visible vulnerabilities, though it lacks explicit security policies or incident response information. Overall, the domain registration and hosting details align well with the website's public sector role, 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

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 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';…

  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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention bznb.de, from OffSeq Breach.

No leaked records found

Breach holds no records for bznb.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The organization operates as an important public sector entity focused on telecommunications infrastructure development in Niedersachsen and Bremen. Its business model revolves around advisory services, funding guidance, and providing digital infrastructure data atlases. The website reflects a stable market position as a regional authority, supported by partnerships such as NETZ - Zentrum für innovative Technologie Osterholz GmbH. The absence of commercial advertising and the presence of official logos and legal references reinforce its credibility. Growth indicators include active news updates and multiple project-related resources. The partnership ecosystem is centered on regional technology and government bodies.

Security posture

The website demonstrates a baseline security maturity with enforced HTTPS and cookie consent. However, it lacks advanced security headers and publicly available security or incident response policies. No vulnerability disclosure mechanisms or security.txt files are present, which could limit external reporting of security issues. The absence of exposed sensitive data and minimal third-party tracking reduces risk exposure. Compliance with GDPR is indicated by the privacy and cookie policies. Overall, the security posture is adequate for a public information site but could be enhanced by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Introduce a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party scripts and CMS extensions to mitigate potential vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance and trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, enhanced with the Yoast SEO plugin for search engine optimization. It uses JavaScript libraries such as Owl Carousel for interactive elements and CKEditor for content editing. Hosting is provided by webhosting-franken.de, with domain name servers aligned accordingly. The site is mobile optimized with responsive images and viewport settings. Performance is moderate, with no major technical issues detected in the HTML structure. However, security headers are missing, and no advanced analytics or tracking services are detected, indicating a privacy-conscious setup. Opportunities exist to improve security headers and 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.
