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

RWE is a major global energy company with a strong focus on renewable energy and sustainability. With over 125 years of history, it has transformed into a leading supplier of clean, safe, and affordable electricity. The company operates a diversified portfolio including renewable energies such as solar, wind (onshore and offshore), hydrogen, battery storage, and bioenergy, alongside conventional energy sources. RWE also invests in energy transition projects and provides related services including energy trading and procurement portals. The website reflects a mature corporate presence with comprehensive information for investors, partners, and job seekers. Technically, the website employs modern web technologies including jQuery, UIkit framework, Google Tag Manager, and Usercentrics for consent management. The site is mobile-optimized, accessible, and SEO-friendly, with fast loading times and structured navigation. The CMS appears to be Progress Sitefinity, supporting a robust content management environment. From a security perspective, the site enforces HTTPS with strong SSL configuration and implements standard security headers. Consent management and privacy policies are comprehensive and GDPR compliant. However, explicit incident response contacts and vulnerability disclosure policies are not publicly visible, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected. Overall, the site is professional, trustworthy, and well-maintained, supporting RWE's market position as a leading energy supplier. The absence of WHOIS data for the domain is unusual but does not detract significantly from the site's credibility given the corporate branding and content quality.

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. 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 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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

RWE holds a strong market position as a leading global energy supplier with a clear strategic focus on renewable energy and sustainability. Its business model integrates energy production from diverse sources, energy trading, and investment in energy transition technologies. The company targets a broad audience including investors, partners, customers, and potential employees. RWE's extensive subsidiary network and international presence support its growth and innovation agenda. The website's detailed sections on corporate governance, compliance, and sustainability reports indicate a transparent and responsible corporate culture. Partnerships and regional sites further extend its ecosystem. The company leverages digital tools for stakeholder engagement and operational efficiency.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and privacy compliance mechanisms including cookie consent management. The absence of exposed sensitive data and use of secure forms indicate good security hygiene. However, the lack of publicly available incident response contacts and vulnerability disclosure policies suggests room for enhancement in transparency and proactive security communication. The presence of ISO 27001 certification is a positive indicator of organizational security standards. Overall, the security posture is strong but could benefit from explicit incident response and vulnerability disclosure information to improve stakeholder trust and readiness.

Recommendations

  1. Publish clear incident response contact information and procedures on the website to enhance transparency and readiness.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file to encourage responsible reporting of security issues.
  3. Maintain and highlight security certifications and compliance achievements prominently to reinforce trust.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance data retention policy disclosures related to analytics and user data to improve privacy compliance.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, UIkit framework, and integrates third-party services such as Google Tag Manager and Usercentrics for analytics and consent management. The CMS is likely Progress Sitefinity, supporting structured content delivery and multi-language capabilities. Performance is moderate with good mobile optimization and accessibility features. The site uses SVG graphics for logos and icons, contributing to visual quality. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to improve technical documentation of security policies and incident response mechanisms.
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.
