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. 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"

    • 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

CBXNET holds a strong market position as a regional internet pioneer in Berlin, leveraging its own microwave radio network and data centers to offer broadband internet and IT infrastructure services. Their business model centers on providing flexible, secure, and scalable internet and IT solutions to SMEs and event organizers, supported by partnerships with recognized technology and network providers. The company demonstrates growth through diversified service offerings including cloud services and event internet solutions. Their partnership ecosystem includes BCIX, euNetworks, RIPE, Sophos, and others, enhancing their service reliability and market reach. The website content and testimonials reflect a customer-centric approach and operational reliability, positioning CBXNET as a trusted provider in the regional telecommunications sector.

Security posture

The website employs HTTPS and secure form handling with client-side validation, indicating a baseline security maturity. However, no explicit HTTP security headers were detected in the provided data, suggesting room for enhancement in defense-in-depth measures. There is no publicly available security policy or incident response information, which could be improved to demonstrate readiness and transparency. No vulnerabilities or exposed sensitive data were found in the HTML content. Privacy policies are comprehensive and GDPR compliant, reflecting good data protection practices. Overall, the security posture is moderate to good but would benefit from formalized security documentation and enhanced HTTP header configurations.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Conduct regular security audits and update CMS and plugins to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider deploying DNSSEC to improve domain name system security and trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system, combined with Bootstrap for responsive design and Google Maps API for location services. The use of LESS CSS and FontAwesome icons indicates a modern frontend approach. Google Analytics is integrated for traffic analysis. The site is mobile-optimized with good navigation clarity and professional design. Performance is moderate, with potential improvements in loading speed and accessibility. Hosting provider details are not explicitly identified. The technical stack supports the business needs effectively but could benefit from enhanced security headers and accessibility improvements.
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.
