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

Meteodyn is a specialized company with over 20 years of experience in Computational Fluid Dynamics (CFD) simulation focused on wind engineering, climatology, and meteorology. Their website reflects a professional B2B service model targeting organizations requiring expert wind flow analysis and consulting, primarily in the energy sector. The company is positioned as a recognized expert with a niche focus, supported by a consistent brand presence and quality content. Technically, the website is built on WordPress using the Divi theme and WooCommerce plugin, integrating modern JavaScript libraries such as Swiper.js and Tippy.js. It employs Google Analytics and Google Tag Manager for analytics, with privacy-conscious consent management via Cookiebot. The site is mobile optimized and SEO friendly, though accessibility features are basic. From a security perspective, the website uses HTTPS and manages cookie consent responsibly. However, it lacks DNSSEC, security headers, and published security policies or incident response contacts. No privacy policy or terms of service were found, which are important for compliance and user trust. The WHOIS data is consistent with the business claims, showing a long-established domain registered with a reputable registrar. Overall, the website is professional and trustworthy but would benefit from enhanced privacy and security documentation and technical improvements to strengthen its security posture and compliance standing.

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

5 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';…

  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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Meteodyn operates in the energy sector, providing specialized CFD simulation and wind engineering consulting services. Their market positioning as a 20-year expert indicates a stable niche presence with a focus on technical excellence. The business model is B2B, targeting professionals and organizations needing precise wind flow analysis. The website suggests a small-sized company based in France with no visible parent or subsidiary companies. The use of WooCommerce hints at possible product sales or service bookings online. The company leverages partnerships with technology providers like Cookiebot and Google for analytics and consent management. Growth indicators include a well-maintained website and integration of multilingual support via WPML, suggesting international reach or ambitions.

Security posture

The security maturity level is moderate. HTTPS is enforced, and cookie consent is managed with explicit denial of ad personalization by default, reflecting good privacy awareness. However, the absence of DNSSEC, security headers, and published security or incident response policies indicates gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the provided content. The lack of a privacy policy and terms of service is a compliance gap, especially under GDPR. Incident response readiness appears minimal due to missing contact channels for security issues. Overall, the security culture is basic but can be improved with documented policies and technical enhancements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Create and publish a security policy and incident response contact information, including abuse and security email addresses.
  5. Conduct regular security audits and vulnerability scans of WordPress plugins and themes to mitigate risks.

Technical notes

Notes

The website is built on a mature WordPress platform using the Divi theme and WooCommerce plugin, indicating a flexible and widely supported infrastructure. It integrates modern JavaScript libraries for UI enhancements and uses Google services for analytics and tag management. Cookie consent is managed via Cookiebot, reflecting attention to privacy regulations. Performance is moderate, with good mobile optimization and SEO practices. However, accessibility features are basic and could be improved. Hosting details are not explicit but the domain registrar is IONOS SE, a reputable provider. The site uses multiple external domains for fonts, analytics, and consent management, all reputable. Technical risks include the lack of DNSSEC and missing security headers, which should be addressed to reduce attack surface and improve resilience.
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.
