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

8 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 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';…

  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 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, YouTube, Google APIs

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

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

BluenetNTS operates in the renewable energy sector, focusing on photovoltaic installations, heat pumps, wind turbines, and related consulting services. Their business model revolves around project-based installations and ongoing service and monitoring, supported by grant advisory services. The company targets residential buildings, municipalities, and commercial enterprises, indicating a diversified client base. The presence of career opportunities and media mentions suggests growth and market engagement. The company leverages partnerships with technology providers and uses a modern web platform to engage customers. Revenue streams likely include installation contracts, maintenance services, and consulting fees. The company maintains a consistent brand and professional online presence, enhancing credibility in a competitive market.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of Google reCAPTCHA to protect forms, and a GDPR-compliant cookie consent mechanism via the Complianz plugin. However, there is no publicly available security policy or incident response plan, which limits transparency and preparedness perception. Security headers and advanced configurations are not explicitly visible, suggesting potential areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party analytics and tracking scripts requires ongoing monitoring to mitigate privacy risks. Overall, the security posture is adequate for the business type but would benefit from documented policies and improved header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Implement and publicly disclose a security policy and incident response plan to enhance trust and preparedness.
  3. Add and verify security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure GDPR compliance.
  5. Enhance website accessibility features to improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder, Yoast SEO for optimization, and integrates Google Tag Manager and Hotjar for analytics and user behavior tracking. The site uses Google reCAPTCHA for form security and Complianz for GDPR cookie consent management. Performance is moderate with responsive design and mobile optimization evident. The presence of multiple CSS and JS libraries indicates a feature-rich site but may introduce technical debt if not regularly maintained. Hosting provider details are not explicit, but the domain is registered with a reputable registrar. Opportunities exist to improve accessibility and security header implementation to reduce technical 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.
