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. 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 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

      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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

The business operates in the energy and retail sectors, leveraging an e-commerce model to distribute Viessmann's product portfolio. The site integrates multiple marketing and analytics tools to optimize customer engagement and conversion. The presence of social media links and official corporate references indicates a strong brand presence and partnership ecosystem. The domain age and registration details align with the business's recent establishment and growth trajectory.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and a Content Security Policy header in place. Cookie consent mechanisms comply with GDPR requirements, and third-party scripts are managed with user consent. However, the absence of DNSSEC and additional security headers suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Add additional security headers such as X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Conduct regular audits of third-party scripts to mitigate supply chain risks.
  5. Improve accessibility features to meet higher compliance standards.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Bootstrap, Swiper.js, and integrates with Google Tag Manager, Facebook Pixel, Hotjar, and Salesmanago for analytics and marketing. It is built on the SOTE e-commerce platform, which provides CMS and e-commerce functionalities. The site is mobile-optimized with responsive design and good SEO practices. Performance is moderate, with lazy loading and caching mechanisms observed. The technical implementation is solid but could benefit from enhanced accessibility and security header configurations.
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.
