Risk levelLow

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

Vestas is a globally recognized leader in the renewable energy sector, specializing in the design, manufacture, installation, and servicing of wind turbines worldwide. The company targets businesses and governments seeking sustainable energy solutions, positioning itself as a key player in the energy industry with a comprehensive portfolio of wind energy services. The website reflects this stature with professional design, clear branding, and detailed service descriptions, catering to an enterprise-level audience. Technically, the website leverages a modern technology stack including Adobe Experience Manager as its CMS, Adobe Experience Cloud for marketing, Google Tag Manager, and multiple analytics platforms such as Google Analytics, Piwik PRO, and Hotjar. Hosting and security are supported by Cloudflare, ensuring fast performance and robust SSL configurations. The site is mobile-optimized and accessible, with a strong focus on privacy compliance demonstrated by a comprehensive cookie consent mechanism and GDPR-aligned policies. From a security perspective, the site enforces HTTPS and employs reputable third-party services for analytics and performance monitoring. However, explicit security headers are not clearly visible in the HTML content, and no public security or incident response policies are found, which could be areas for improvement. The absence of WHOIS data is noted but likely due to privacy protection, common for large enterprises. Overall, the website presents a low-risk profile with strong business credibility and technical maturity. Strategic recommendations include enhancing visible security policies, publishing vulnerability disclosure information, and providing clearer contact channels for security incidents to further strengthen trust and 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

1 finding rated critical or high. Fix these first.

  1. 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

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

Vestas operates as an essential entity within the energy sector, focusing on renewable wind energy solutions. Its business model is B2B, serving governments and large enterprises with wind turbine products and services. The company maintains a strong global presence with localized domains for key markets including Germany, China, India, Japan, the US, and Canada. Vestas leverages partnerships with major analytics and marketing platforms to optimize customer engagement and operational insights. The company’s growth is supported by its leadership position in sustainable energy, a sector with increasing global demand. The website’s comprehensive cookie and privacy policies reflect a mature approach to regulatory compliance and user trust.

Security posture

The security posture of the Vestas website is robust with mandatory HTTPS and use of Cloudflare for protection and performance. The site integrates multiple analytics and monitoring tools, which are industry-standard and reputable. The cookie consent mechanism is detailed and GDPR-compliant, indicating strong privacy practices. However, the lack of explicit security headers in the HTML and absence of a public security policy or incident response contact reduces transparency. No vulnerabilities or exposed sensitive data were detected in the provided content. The WHOIS data absence is a minor concern but likely due to privacy protection. Overall, the security maturity is high but could benefit from enhanced transparency and published security documentation.

Recommendations

  1. Publish explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve browser security.
  2. Create and publish a dedicated security policy and incident response page to increase transparency and user trust.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Provide clear and accessible contact information for security incidents, including dedicated security or abuse email addresses.
  5. Regularly audit and update third-party scripts and analytics tools to mitigate potential vulnerabilities.

It uses Google Tag Manager to manage analytics and tracking scripts efficiently. Performance is optimized via Cloudflare CDN and security services. The site is mobile-responsive with good accessibility features and SEO optimization. The technology stack includes advanced analytics platforms like Piwik PRO and Hotjar for user behavior insights.

Opportunities exist to enhance security headers and publish more security-related documentation.
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.
