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.

      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

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

Vattenfall holds a dominant position in the Swedish energy market, focusing on fossil-free electricity production and retail. Their business model integrates energy sales with complementary services like solar installations and electric vehicle charging, catering to environmentally conscious consumers. The company leverages digital tools for customer engagement and analytics, indicating a data-driven approach. Partnerships and subsidiaries such as Vattenfall Eldistribution support their infrastructure. The website content and structure suggest a large enterprise with comprehensive service offerings and a strong brand identity.

Security posture

The website demonstrates a solid security foundation with HTTPS and GDPR-compliant consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and vulnerability management. The use of third-party scripts like Optimizely and Piwik PRO is managed with consent, minimizing privacy risks. Overall, the security maturity is good but could benefit from enhanced security headers and published policies.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection against common web attacks.
  3. Consider publishing a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by providing clear data retention policies and detailed privacy notices.

Technical notes

Notes

The website is built using modern web technologies, primarily Angular framework version 20, with integration of Optimizely for experimentation and Piwik PRO for analytics. The site uses custom fonts hosted on their own CDN and employs a comprehensive consent management platform to comply with GDPR. Performance is moderate with good mobile optimization and accessibility features. The site structure is clear and navigation is intuitive, supporting a positive user experience. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details were not found in the HTML content.
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.
