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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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, LinkedIn, Google APIs

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

  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

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

Helexia Portugal operates in the energy sector focusing on decarbonization and sustainability solutions for various industries. Their competitive advantage lies in integrated service offerings from consultancy to investment, backed by certifications and a portfolio of reputable clients. The business model revolves around providing turnkey energy solutions including solar energy production, energy efficiency, electric mobility, and energy management services. The company targets medium to large enterprises aiming to reduce carbon footprint and optimize energy consumption. Growth indicators include active project portfolios, case studies, and partnerships with sustainability-focused platforms. The company maintains a strong digital presence with active social media channels and a well-structured website supporting lead generation and client engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and use of consent management for cookies, aligning with GDPR requirements. The presence of multiple analytics and tracking tools is managed with user consent, indicating privacy awareness. However, the lack of explicit security headers such as Content-Security-Policy and absence of a security.txt file or incident response contacts highlight areas for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The site uses reputable third-party scripts and plugins, minimizing risk exposure. Overall, the security posture is good but could benefit from enhanced header policies and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement a comprehensive Content-Security-Policy header to mitigate XSS and related attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add clear incident response contact information, such as a dedicated security or abuse email.
  4. Regularly review and update third-party scripts and plugins to avoid vulnerabilities.
  5. Enhance security headers including X-Frame-Options, Referrer-Policy, and Permissions-Policy.

Technical notes

Notes

The website is built on a modern WordPress platform using Bootstrap 5 for responsive design and jQuery for scripting. It integrates multiple analytics and marketing tools including Google Analytics, Microsoft Clarity, Hotjar, and LinkedIn Insight Tag, all managed with user consent via Cookie Script. The site uses SVG support and optimized fonts loaded from Google Fonts. Performance is moderate with asynchronous loading of scripts and prefetching enabled. The site is mobile-optimized with good accessibility and SEO practices, including structured data (JSON-LD) for organization and webpage metadata. Technical risks are minimal but could be reduced further by tightening security headers and monitoring 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.
