W.E.B. Windenergie CZ is a Czech renewable energy company specializing in the development, realization, and operation of wind and solar power plants. With over 23 years of experience, the company positions itself as an established player in the Czech renewable energy market, targeting both business clients and consumers interested in sustainable energy solutions. The website is professionally designed, localized in Czech, and provides clear navigation and relevant business information. Technically, the site is built on TYPO3 CMS, employs modern web technologies including Google reCAPTCHA for bot protection, and uses Matomo analytics for user tracking. The cookie consent mechanism is comprehensive and GDPR compliant, reflecting a good privacy posture. Security-wise, HTTPS is enforced, but some security headers are missing, and no explicit security policy or incident response information is published.

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. 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 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

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn

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

  3. 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

The company operates in the energy sector focusing on renewable sources, primarily wind and solar. Its business model revolves around project development, implementation, and ongoing operation of energy plants. The website content and structure indicate a medium-sized enterprise with a clear market position in the Czech Republic. The absence of explicit contact emails or phone numbers on the main page suggests reliance on contact forms for communication. The company maintains a multi-country presence with related domains for Austria, Germany, France, Italy, Slovakia, USA, and international markets, indicating a broad partnership or subsidiary network. Marketing and advertising practices include use of Facebook and Google ad networks and retargeting services, with Matomo analytics for data collection. The company demonstrates good compliance with privacy regulations and transparent cookie management.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms from automated abuse. A detailed cookie consent banner with opt-in for marketing and statistics cookies is implemented, supporting GDPR compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No security.txt or explicit incident response contact information is found, which is a gap in security transparency and readiness. The WHOIS data is privacy protected, limiting domain trust assessment. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is good but could be improved by adding missing headers and publishing security policies.

Recommendations

  1. Add and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Verify and secure all forms with proper input validation and sanitization beyond reCAPTCHA.
  4. Consider publishing WHOIS data or providing verified registrant information to increase domain trustworthiness.
  5. Maintain and regularly update cookie and privacy policies to reflect evolving regulations and user expectations.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system, indicating a stable technical foundation. It uses modern web technologies including asynchronous JavaScript loading, Google reCAPTCHA for bot mitigation, and Matomo for analytics. The site is mobile optimized with responsive images and accessible navigation. Performance is moderate, with some room for optimization in loading speed. SEO is supported by proper meta tags and structured data in JSON-LD format. No critical technical debt or outdated libraries were detected. Opportunities exist to improve security headers and enhance incident response capabilities.
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.
