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

Vestas is a global leader in sustainable energy solutions, specializing in the design, manufacture, installation, and servicing of wind turbines worldwide. The company targets businesses, investors, and sustainability-focused stakeholders, maintaining a strong market position supported by decades of expertise and a large installed base. Their website reflects a mature digital presence with comprehensive content, multi-language support, and strong branding consistency. Technically, the site is built on Adobe Experience Manager with integrations of modern analytics and marketing tools such as Google Analytics, Hotjar, Amplitude, and LinkedIn Insights. The site is mobile-optimized and accessible, with good SEO practices. However, the SSL certificate is invalid or missing, which is a critical security flaw. Security posture shows presence of key headers like CSP and X-Frame-Options, but lacks a valid SSL certificate and proper HSTS configuration. No explicit security policies or incident response contacts are found. Privacy compliance is well addressed with clear cookie consent mechanisms and a comprehensive privacy policy. Overall, the site is professional and trustworthy but must urgently address SSL certificate issues to ensure secure user interactions and maintain trust.

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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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 in the renewable energy sector with a focus on wind power solutions. Their business model includes product sales (wind turbines), service contracts, and project development. The company has a global footprint with operations in multiple countries and a workforce of over 30,000 employees. Their investor relations and sustainability reporting indicate transparency and commitment to ESG principles. The website supports recruitment efforts and customer engagement through dedicated portals and content. The company leverages partnerships for marketing, analytics, and cookie management, integrating services from Adobe, Google, LinkedIn, and others. Their strong social media presence across major platforms supports brand awareness and stakeholder engagement.

Security posture

The website demonstrates moderate security maturity with implementation of several security headers and a content security policy restricting resource loading to trusted domains. However, the absence of a valid SSL certificate severely undermines the security posture, exposing users to risks such as data interception and man-in-the-middle attacks. HSTS is configured in headers but not effectively enabled, and OCSP stapling is missing, reducing SSL performance and security. No visible incident response or vulnerability disclosure information is provided, which could hinder timely reporting and mitigation of security issues. The site uses modern analytics and marketing scripts, which require careful management to avoid privacy risks. Overall, the security posture requires immediate improvement in SSL management and enhanced transparency in security policies.

Recommendations

  1. Obtain and deploy a valid SSL certificate immediately to enable HTTPS and protect user data.
  2. Enable and configure HSTS with includeSubDomains and preload flags to enforce secure connections.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish a clear security policy and incident response contact information to enhance transparency and trust.
  5. Regularly audit third-party scripts and CSP to minimize risks from unsafe inline scripts and external resources.

Technical notes

Notes

The website is built on a robust CMS platform (Adobe Experience Manager) with a modern tech stack including Adobe Launch, Google Tag Manager, and various analytics tools. The site is well-structured with responsive design and accessibility features. Performance data is not available, but the use of CDNs and caching headers suggests optimization efforts. The site uses extensive external integrations for marketing, analytics, and social media embedding, which require ongoing management to ensure privacy compliance and security. The invalid SSL certificate is a critical technical risk that must be addressed to avoid user trust erosion and potential security breaches.
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.
