Risk levelLow

0–100, higher is better. How it is calculated

Ellevio is a major Swedish electricity distribution company serving nearly one million customers. The company focuses on driving electrification and investing in sustainable energy solutions to support an electrified society. The website content is primarily in Swedish and targets local customers and stakeholders interested in energy distribution and sustainability. Technically, the website employs modern analytics tools such as Matomo and Microsoft Application Insights, along with a comprehensive cookie consent mechanism powered by Cookiebot, indicating a mature digital infrastructure. The site uses HTTPS and integrates customer chat services, enhancing user engagement and support. Security posture is generally good with encrypted connections and privacy-focused analytics, but lacks explicit security policies and some security headers. The absence of WHOIS data for the exact domain queried suggests it may be a subdomain or the query was not for the registered domain, which slightly reduces transparency. Overall, the website is professional, secure, and compliant with cookie consent regulations, but could improve by publishing clear privacy and security policies and providing direct contact information.

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

2 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Ellevio holds a strong market position in the Swedish energy sector as a large electricity distributor. Its business model revolves around electricity distribution and sustainable energy investments, targeting residential and commercial customers in Sweden. The company leverages partnerships with technology providers for analytics and customer engagement. The website reflects a focus on transparency and compliance with GDPR through detailed cookie consent, although explicit privacy policies are not evident in the provided content. The digital presence supports customer service and operational transparency but could benefit from enhanced contact channels and security disclosures. The use of advanced telemetry and analytics tools indicates a data-driven approach to service improvement and customer insights.

Security posture

The website demonstrates a solid security foundation with HTTPS encryption and the use of privacy-respecting analytics tools. The cookie consent mechanism is robust, allowing granular user control over cookie categories. However, the site lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended best practices. No direct evidence of vulnerabilities or exposed sensitive data was found. The absence of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is good but could be enhanced by implementing additional HTTP security headers and publishing formal security and incident response policies.

Recommendations

  1. Publish a clear and comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  3. Provide explicit contact information including company emails and phone numbers for customer support and security incident reporting.
  4. Implement and publicize a security policy and incident response plan to enhance trust and compliance.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website uses a modern technology stack including Microsoft Application Insights for telemetry, Matomo for analytics, Cookiebot for consent management, and jQuery for client-side scripting. Hosting appears to be on Microsoft Azure, inferred from telemetry and cookie data. The site loads multiple external scripts asynchronously to optimize performance. Mobile optimization is good, and SEO meta tags are properly configured. Accessibility features are basic but present. The site lacks a detected CMS, suggesting a custom or proprietary platform. Performance is moderate with room for improvement in loading speed and accessibility compliance. The technical infrastructure supports a professional and scalable web presence suitable for a large energy company.
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.
