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

5 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.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  2. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 9 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

ALDI Mobile positions itself as a competitive low-cost mobile network operator in Switzerland, leveraging the strong brand of ALDI SUISSE AG. Its business model focuses on prepaid and subscription mobile services with an emphasis on fair pricing and network quality. The company benefits from a large retail presence and brand recognition, targeting a broad consumer base. The website supports customer engagement through clear contact channels and a dedicated app portal. While no explicit certifications or partnerships are listed, the domain and business information align well, indicating a stable and credible operation. Growth potential lies in expanding digital services and enhancing customer support capabilities.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement and comprehensive security headers. Cookie consent is managed via Cookiebot, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contact, or vulnerability disclosure program represents an area for improvement. The use of third-party scripts like Google Tag Manager is standard but requires ongoing monitoring for security risks. Overall, the security measures are adequate for the business type but could be enhanced by formalizing security governance and incident management transparency.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact or page to improve transparency and readiness.
  3. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance trust signals by adding certifications or compliance badges relevant to telecommunications.

Technical notes

Notes

The website is built on a modern React and Next.js stack, enabling server-side rendering and optimized performance. It uses Google Tag Manager and Cookiebot for analytics and consent management, reflecting a mature digital marketing approach. The site is mobile-optimized with responsive design and accessibility features, contributing to a positive user experience. No common CMS was detected, suggesting a custom or proprietary content management solution. Hosting details are not explicit but performance indicators suggest a reliable infrastructure. Opportunities exist to further improve SEO and accessibility by adding structured data and ARIA attributes. Technical risks are minimal but require continuous monitoring of third-party dependencies.
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.
