CBXNET operates as a regional Wireless Internet Service Provider specializing in broadband internet connections via directional radio (Richtfunk) technology in the Berlin-Brandenburg area. Their website richtfunk.berlin focuses on business internet solutions including symmetrical high-speed connections, backup redundancy, site networking, and multi-tenant infrastructure. The company targets small to medium enterprises, healthcare, finance, education, and property management sectors, positioning itself as a reliable and flexible alternative to traditional telecom providers, especially in under-served areas. Technically, the website is built on TYPO3 CMS with Bootstrap and integrates Google Analytics and Google Maps APIs. The site is mobile-optimized and well-structured, offering a professional user experience. Security posture is solid with HTTPS enforced and domain transfer protections, though improvements such as DNSSEC and security headers are recommended. Privacy compliance is partially met with a comprehensive privacy policy linked on the parent domain but lacks a cookie consent mechanism. Overall, the security posture is good with no detected vulnerabilities or blocking mechanisms. The domain registration is consistent with the business history, enhancing trustworthiness. The site content is safe for general audiences and professionally presented, supporting CBXNET's credibility as a regional telecom provider.

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

8 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

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

    • 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

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 regional market position as a pioneer in wireless broadband services in Berlin-Brandenburg. Their business model focuses on providing flexible, high-availability internet solutions tailored to business needs, including backup and multi-tenant options. The company leverages partnerships and subsidiary domains to extend cloud and event internet services. Their customer base includes diverse sectors requiring reliable internet connectivity. The website content and references to notable clients indicate a stable and growing business with a focus on quality service delivery and customer support.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and security headers such as Content Security Policy and HSTS represents areas for improvement. No incident response or vulnerability disclosure information is published, which could enhance transparency and readiness. The lack of a cookie consent mechanism is a GDPR compliance gap. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is good but could benefit from implementing recommended best practices.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  4. Publish an explicit security policy and incident response contact information on the website.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to improve transparency and trust.

Technical notes

Notes

The website uses TYPO3 CMS with Bootstrap framework, integrating Google Analytics and Google Maps APIs. The site is mobile responsive and well-structured with good SEO meta tags. Performance is moderate, with room for optimization. The domain is registered with InterNetX GmbH since 2014, indicating stable ownership. The site lacks advanced security headers and DNSSEC, which are recommended for modern web security. No major technical debt or outdated libraries were detected. Overall, the technical infrastructure supports the business needs effectively but can be enhanced for security and performance.
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.
