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

1 finding rated critical or high. Fix these first.

  1. 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 SSL Key Length

      SSL certificate uses 256-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

Revendo operates in the niche market of used Apple devices in Switzerland, leveraging a direct-to-consumer e-commerce model. Its competitive advantage lies in specialization, warranty offerings, and a seamless online shopping experience powered by Shopify. The integration with review platforms and marketing tools suggests a focus on customer trust and retention. The presence of a partner domain for device selling indicates an ecosystem approach. The business targets tech-savvy consumers seeking value and sustainability through refurbished products. Growth potential is supported by digital marketing and positive customer feedback. No parent or subsidiary companies were identified, indicating an independent operation.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and multiple security headers present, reducing common web vulnerabilities. Payment processing is handled via Shopify Payments and Apple Pay, both secure and PCI-compliant. The cookie consent banner and privacy policy indicate GDPR awareness and compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy or incident response page and lack of a vulnerability disclosure program are gaps that could be addressed to enhance transparency and readiness. Overall, the site is secure for e-commerce operations but could improve in formalizing security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add explicit incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts to mitigate supply chain risks.
  5. Enhance visibility of data protection officer contact information to improve GDPR transparency.

Technical notes

Notes

Revendo's website is built on the Shopify platform using the Ignite theme version 2.3.0, ensuring a modern and responsive design. The tech stack includes JavaScript libraries for analytics, marketing, and customer reviews, such as Klaviyo, Microsoft Clarity, Trustpilot, and Judge.me. The site uses Shopify's CDN for hosting, contributing to fast load times and reliable performance. Accessibility and SEO optimizations are evident through proper meta tags, language attributes, and structured data. The site employs advanced tracking and marketing pixels while maintaining user privacy through consent mechanisms. Technical debt appears minimal, with opportunities to further modernize by consolidating third-party scripts and enhancing security documentation.
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.
