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 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

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

BITel holds a solid position as a regional telecommunications provider with a focus on fiber optic expansion and high-speed internet services. Its business model leverages partnerships with local utilities and specialized service providers like Westconnect and waipu.tv to offer bundled services. The target market is private customers in specific German regions, with a medium-sized operational scale. The company benefits from parent company support, enhancing its market credibility and infrastructure capabilities. The website content and structure indicate a customer-centric approach with clear service descriptions, availability checks, and support resources. Marketing efforts include targeted regional campaigns and digital tracking compliant with privacy regulations.

Security posture

The website demonstrates a good security posture with HTTPS enabled and the use of consent management for cookies, reflecting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options are not visible in the provided data and could be improved. The absence of a public security policy or incident response contact is noted, which could enhance transparency and trust. Third-party scripts like Facebook Pixel and Google Tag Manager are used responsibly with consent mechanisms in place. Overall, the security maturity is appropriate for the business size and industry, with room for incremental improvements.

Recommendations

  1. Publish explicit security headers (X-Frame-Options, X-Content-Type-Options) to enhance protection against clickjacking and MIME sniffing.
  2. Provide a publicly accessible security policy and incident response contact information to improve transparency and customer trust.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance performance optimization to improve loading speed and user experience.
  5. Continue maintaining and updating privacy and cookie consent mechanisms to stay compliant with evolving regulations.

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable and maintainable technical foundation. Integration of Google Tag Manager and Facebook Pixel shows active marketing and analytics usage. The site is mobile optimized with responsive design and accessibility considerations. Performance is moderate, with potential for optimization in image loading and script management. The use of consentmanager.net for cookie consent reflects attention to privacy compliance. No hosting provider details were explicitly found, but domain name servers indicate a dedicated infrastructure. Overall, the technical stack is modern and appropriate for a regional telecommunications provider.
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.
