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. 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

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

WEtell operates in the telecommunications sector with a niche focus on sustainability and social responsibility. Its business model centers on providing mobile plans that are climate-neutral and fair, targeting environmentally conscious consumers and businesses in Germany. The company leverages community involvement and crowdfunding to support infrastructure development. Its competitive advantage lies in transparent pricing, ethical business practices, and certifications from recognized sustainability organizations. The presence of multiple social media channels and customer testimonials indicates active engagement and growing brand trust. The company appears to be in a growth phase with a clear market differentiation strategy.

Security posture

The website demonstrates a mature security posture with HTTPS enabled, CSRF tokens in forms, and cookie consent mechanisms compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response contact details represents a compliance gap. There is no evidence of a security.txt file or vulnerability disclosure program. Security headers were not explicitly detected in the provided data, suggesting potential room for improvement. Overall, the security posture is good but could be strengthened by formalizing policies and improving transparency around incident handling.

Recommendations

  1. Publish a formal security policy page detailing security practices and commitments.
  2. Provide clear incident response contact information, such as a dedicated security@ or abuse@ email address.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Review and enhance HTTP security headers like Content-Security-Policy and X-Frame-Options.
  5. Continue maintaining GDPR compliance and transparency in data collection and cookie management.

Technical notes

Notes

The website uses a modern and lightweight JavaScript stack including Alpine.js for reactive UI components and Swiper.js for interactive sliders. Matomo analytics is used for privacy-respecting user tracking, complemented by Cookiebot for consent management. The site appears to be custom-built or uses an undetected CMS, with no obvious technical debt or deprecated technologies. Performance is moderate with lazy loading of images and asynchronous script loading. Mobile optimization and accessibility are well addressed, with semantic HTML and ARIA attributes. Hosting details are not explicit but the use of green-internet.net nameservers aligns with the sustainability theme. Overall, the technical infrastructure supports a professional and user-friendly experience.
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.
