73/100

Risk levelMedium

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

Neoenergia is a large Brazilian energy company operating in generation, transmission, distribution, and commercialization of electricity across 18 states and the Federal District. The website reflects a mature corporate presence with detailed governance, sustainability, and social responsibility content, targeting energy consumers, investors, and partners. The technical infrastructure is based on the Liferay CMS platform with modern JavaScript frameworks and extensive use of analytics and tracking tools, indicating a digitally mature environment. Security posture is strong with HTTPS, CSP, and secure forms, though explicit incident response and vulnerability disclosure information are lacking. The absence of WHOIS data raises concerns about domain registration legitimacy, warranting further verification. Overall, the website is professional and trustworthy but could improve transparency in security and privacy compliance.

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

6 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 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

    • High

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

Neoenergia holds a significant market position in Brazil's energy sector, leveraging a diversified business model covering all major energy value chain segments. The company targets a broad audience including residential and commercial energy consumers, investors, and regulatory bodies. The website's investor relations and governance sections indicate a focus on transparency and compliance. Partnerships with Iberdrola and other entities are evident. The business model is supported by digital engagement through multi-language support and comprehensive content. Growth indicators include sustainability initiatives and innovation programs. The company maintains a strong brand presence with consistent messaging and trust signals such as governance and social commitment.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, Content Security Policy with nonce, and secure input forms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security.txt or explicit incident response contacts limits transparency and readiness perception. Cookie consent mechanisms are present but could be enhanced for clarity and GDPR compliance. The extensive use of third-party analytics and tracking scripts increases the attack surface and privacy risk, necessitating regular audits. Overall, the security maturity is good but can be improved by formalizing vulnerability disclosure and incident response processes.

Recommendations

  1. Publish a security.txt file and vulnerability disclosure policy to enhance transparency and trust.
  2. Provide clear incident response contact information on the website.
  3. Enhance cookie consent mechanisms to fully comply with GDPR and other privacy regulations.
  4. Conduct regular security audits of third-party scripts and tracking technologies.
  5. Improve accessibility features to meet higher standards and broaden user inclusivity.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging Alloy UI and React for frontend components. It integrates multiple analytics and tracking services including Google Tag Manager, TikTok Analytics, Microsoft Clarity, Hotjar, and Facebook Pixel. The site uses modern JavaScript libraries such as Swiper.js for UI elements. Performance is moderate with combined and minified resources. Mobile optimization is good with responsive design. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be improved. The lack of hosting provider information limits full infrastructure assessment. Overall, the technical stack is modern and well-implemented with opportunities for optimization and enhanced security controls.
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.
