Swissgrid is the national transmission grid operator in Switzerland, responsible for the safe, stable, and efficient operation of the country's extra-high-voltage electricity grid. The company plays a critical role in ensuring Switzerland's electricity supply security and is actively involved in planning and building the grid of the future to support the energy transition. The website reflects a mature and professional organization with comprehensive information about grid operations, projects, regulation, and market activities. Technically, the website is built on modern frameworks including Angular and Adobe Experience Manager, with good mobile optimization and accessibility. Security posture is strong with HTTPS, security headers, and use of reCAPTCHA for forms, although explicit incident response contacts and vulnerability disclosure mechanisms are not found.

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

4 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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. 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

Swissgrid holds a dominant position as Switzerland's national grid operator, serving energy sector stakeholders, partners, and customers. Its business model centers on grid operation, development, and regulation, with key services including power market management and grid data provision. The company maintains strong governance and compliance frameworks, collaborates with universities on research and development, and communicates transparently with investors and the public. The website content and structure support clear communication of its strategic initiatives such as the 'Grid of the Future' and innovation projects. The absence of direct contact emails or phone numbers on the homepage suggests a controlled communication approach, likely directing inquiries through contact forms or specific pages.

Security posture

The website exhibits a robust security posture with enforced HTTPS, comprehensive security headers, and integration of Google reCAPTCHA to protect forms from automated abuse. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the lack of a published security.txt or vulnerability disclosure policy and absence of explicit incident response contact emails represent areas for improvement. The use of Adobe DTM indicates centralized tag management and analytics, which should be monitored for privacy compliance. Overall, the security maturity is high, suitable for a critical infrastructure operator, but could be enhanced by adding explicit incident response and vulnerability reporting channels.

Recommendations

  1. Publish a dedicated incident response contact page or email address to facilitate security issue reporting.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible disclosure.
  3. Explicitly list any security certifications or compliance attestations to strengthen trust.
  4. Ensure all forms have strong input validation and security controls beyond reCAPTCHA.
  5. Regularly audit third-party scripts and analytics tools for privacy and security compliance.

Technical notes

Notes

The website leverages a modern technology stack including Angular 12 and Adobe Experience Manager CMS, providing a responsive and accessible user experience. Use of Swiper.js enables dynamic content carousels, and Google reCAPTCHA protects interactive elements. The site is well-structured with proper meta tags and Open Graph data for SEO and social sharing. Performance is moderate, likely due to rich media content and third-party scripts. The site is mobile optimized and accessible, with consistent branding and professional design. Hosting details are not explicit but likely managed by a professional provider given the domain and CMS choice. Opportunities exist to improve performance by optimizing image delivery and minimizing third-party dependencies.
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.
