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

Iberdrola is a leading Spanish energy company specializing in electricity and gas supply, offering a variety of tariffs and plans tailored to customer needs. The website targets residential and commercial energy consumers in Spain, providing clear information on services and customer support. The company maintains a strong market position with a professional online presence and consistent branding. Technically, the website is built on the Liferay CMS platform, utilizing modern web technologies including jQuery, React, and various marketing and analytics tools such as Google Tag Manager, OneTrust for consent management, and Visual Website Optimizer. Hosting is supported by Akamai CDN services, ensuring reliable performance and security. From a security perspective, the site enforces HTTPS with strong SSL configurations and implements security headers to protect users. It uses Google reCAPTCHA to secure forms and employs a comprehensive cookie consent mechanism compliant with GDPR. However, explicit security policies and incident response information are not publicly available, representing an area for improvement. Overall, the website demonstrates a mature digital infrastructure with good privacy compliance and business credibility. The absence of critical vulnerabilities and the presence of trust signals contribute to a high trustworthiness rating. Strategic recommendations include publishing detailed security policies, enhancing accessibility, and maintaining vigilance on third-party scripts to sustain security posture.

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

1 finding rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

Iberdrola operates as an essential entity in the energy sector, focusing on electricity and gas supply in Spain. Its business model revolves around providing tailored energy tariffs and customer services, targeting both residential and commercial segments. The company leverages a strong partnership ecosystem and digital marketing tools to maintain competitive advantages. The website reflects a large enterprise scale with consistent branding and professional content, supporting its market leadership. Growth indicators include active customer engagement channels and comprehensive service offerings. The company’s digital presence is well-integrated with social media and consent management, aligning with regulatory requirements and customer expectations.

Security posture

The security maturity of Iberdrola's website is solid, with enforced HTTPS, robust SSL configuration, and implementation of key security headers. The use of Google reCAPTCHA and OneTrust consent management enhances protection against automated abuse and ensures GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the lack of a published security policy or incident response plan limits transparency and preparedness communication. Compliance with GDPR is evident, but further improvements could include explicit vulnerability disclosure mechanisms and enhanced accessibility features. Overall, the security posture supports business continuity and customer trust but can be strengthened by formalizing security governance documentation.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website to improve transparency and preparedness.
  2. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  3. Enhance website accessibility to meet higher standards and improve user experience for all visitors.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential security risks.
  5. Maintain and update consent management practices to align with evolving privacy regulations and user expectations.

Technical notes

Notes

The website is built on a modern and scalable infrastructure using Liferay CMS, React, and jQuery, supported by Akamai CDN for hosting and performance optimization. It integrates multiple marketing and analytics tools such as Google Tag Manager, Bing Insights, and Visual Website Optimizer, managed through a robust consent framework via OneTrust. The site demonstrates good mobile optimization and SEO practices, with structured data enhancing search visibility. Performance is moderate, with opportunities to optimize loading times further. Technical debt appears minimal, but continuous modernization and security audits are recommended to sustain operational excellence and mitigate risks.
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.
