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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

Greenflash operates in the energy sector, targeting industrial and commercial customers with sustainable energy solutions. Their business model is B2B, emphasizing CO2-neutral technologies. The company maintains a consistent brand presence and provides comprehensive privacy and cookie policies, indicating awareness of regulatory requirements. The integration of marketing and analytics tools suggests active customer engagement and data-driven strategies. No partnerships or subsidiaries were identified from the data, indicating a focused operational scope.

Security posture

The website employs HTTPS with good SSL configuration and security headers, enhancing protection against common web threats. Cookie consent is managed via a professional banner with granular controls, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a dedicated security policy or incident response page limits transparency in security governance. The use of third-party scripts like Google Analytics and Facebook Pixel is consented, but ongoing monitoring for vulnerabilities is recommended.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Add incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to improve inclusivity.
  5. Consider implementing a vulnerability disclosure program to foster trust and proactive security.

Technical notes

Notes

The website is built on WordPress with the Divi theme, leveraging Yoast SEO for optimization and Real Cookie Banner Pro for consent management. It integrates Google Tag Manager, Google Analytics, Facebook Pixel, and YouTube embeds, indicating a modern and data-driven tech stack. Performance is moderate with good mobile optimization. Accessibility is basic, suggesting room for improvement. The technical setup is stable with no signs of outdated or vulnerable libraries, supporting reliable business operations.
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.
