Risk levelMedium

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

ACCIONA Energía is a leading global renewable energy company exclusively focused on sustainable energy solutions. The website presents a comprehensive portfolio of renewable technologies including wind, solar, hydroelectric, biomass, and emerging solutions like green hydrogen and electric mobility. The company positions itself as a pioneer in decarbonization with a strong commitment to innovation and environmental impact. Technically, the site is built on Adobe Experience Manager, leveraging modern analytics and marketing tools such as Google Analytics, Hotjar, TikTok, and Twitter tracking, alongside robust cookie consent management via Cookiebot. Security posture is strong with HTTPS, reCAPTCHA, and consent mechanisms, though explicit security headers should be verified. WHOIS data is unavailable, likely due to privacy protection, which slightly impacts trust but is common for large enterprises. Overall, the site is professional, well-structured, and compliant with GDPR, targeting businesses and consumers interested in renewable energy solutions.

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 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

The company operates in the energy sector with a focus on renewable energy generation and supply, targeting a global market across 24 countries. Its business model includes selling renewable energy and providing energy efficiency and decarbonization services to enterprises, institutions, and households. The website reflects a mature digital presence with clear branding, extensive content, and multiple service offerings. Partnerships and parent company links to ACCIONA reinforce credibility. The presence of a contractor profile portal indicates a structured supplier ecosystem. Marketing and analytics tools suggest active customer engagement and data-driven strategies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Google reCAPTCHA v3 to mitigate bots, and a comprehensive cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerabilities were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not explicitly found and should be confirmed. The use of multiple third-party tracking scripts requires ongoing monitoring to prevent privacy risks. Incident response and security policy pages were not found, indicating potential areas for improvement in transparency and readiness.

Recommendations

  1. Verify and implement explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish clear security policy and incident response information to improve transparency and trust with users and partners.
  3. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with evolving regulations.
  4. Consider providing direct contact information for security incidents or data protection officer to enhance incident response capabilities.
  5. Maintain and update cookie consent mechanisms to reflect latest privacy standards and user preferences.

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, indicating a high level of technical maturity. It integrates multiple analytics and marketing technologies including Google Tag Manager, Google Analytics, Hotjar, TikTok, and Twitter tracking pixels, enabling detailed user behavior analysis and targeted marketing. The site uses modern JavaScript modules and asynchronous script loading to optimize performance. Mobile optimization and accessibility features are well implemented, contributing to a positive user experience. Performance is moderate, likely influenced by the number of third-party scripts. The site employs Google reCAPTCHA v3 for bot mitigation and Cookiebot for consent management, reflecting good security and privacy practices. Hosting provider details are not explicit but likely enterprise-grade given the scale and technology stack.
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.
