Security report for axpo.ch

Axpo Schweiz · Energy · Switzerland

Low risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

80/100

Risk levelLow

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

Axpo Schweiz operates as the largest Swiss producer of renewable energy and holds a leading international position in energy trading and marketing of solar and wind power. The website reflects a mature digital presence with comprehensive content, clear navigation, and professional design, targeting Swiss energy consumers, business clients, investors, and media. The technical infrastructure includes modern JavaScript frameworks, Google Tag Manager for analytics, and OneTrust for cookie consent, indicating a focus on privacy and compliance. Security posture is strong with HTTPS enforcement and cookie consent mechanisms, though some security headers could be improved. The absence of WHOIS data limits domain registration trust analysis but the overall website professionalism supports legitimacy. Strategic recommendations include enhancing security headers and publishing explicit security policies to further strengthen trust.

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

3 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 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 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';…

  2. 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

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

Axpo Schweiz is positioned as a key player in the Swiss and international energy markets, focusing on renewable energy production and energy trading. Their business model includes providing tailored energy solutions and digital services related to hydropower, nuclear, solar, and wind energy. The company targets a broad audience including consumers, businesses, and stakeholders interested in sustainable energy. The website content and structure support a strong brand presence and indicate a large enterprise with a well-established market position. Partnerships and related domains such as customer and career portals reinforce their ecosystem. Growth indicators include active communication channels and educational initiatives.

Security posture

The website demonstrates a good security maturity level with HTTPS enabled and cookie consent implemented in compliance with GDPR. No exposed sensitive data or vulnerable libraries were detected. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no publicly available incident response or vulnerability disclosure information, which could be enhanced to improve transparency and readiness. Overall, the security posture is solid but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and enforce Content-Security-Policy and other security headers to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities.
  4. Maintain and update privacy and cookie policies to reflect evolving regulations.
  5. Enhance WHOIS domain registration transparency if possible to improve trust signals.

Technical notes

Notes

The website is built on a modern technology stack including JavaScript, Google Tag Manager, and OneTrust for privacy management. The CMS appears to be Adobe Experience Manager, inferred from client library paths. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site uses external resources such as YouTube embeds and cookie consent scripts. There is no indication of outdated or vulnerable technologies. Opportunities exist to improve security headers and possibly optimize loading speed further.
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.
