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

Green Control s.r.o. is a Czech-based company specializing in comprehensive management and servicing of wind power plants and other energy sources. As part of the MICRONIX Group, it leverages strong industry expertise and resources to provide development, technical, commercial, and financial services to operators and investors in the renewable energy sector. The company holds a significant market position as one of the largest decentralized energy source operators in the Czech Republic, with a focus on wind energy assets. The website reflects a professional business model targeting energy producers and investors, emphasizing operational efficiency and regulatory compliance. Technically, the website is built on WordPress with modern plugins and tracking tools such as Google Analytics and Hotjar. It demonstrates good SEO practices, mobile optimization, and a cookie consent mechanism aligned with GDPR requirements. The site is well-structured with clear navigation and quality content, supporting a positive user experience. From a security perspective, the site uses HTTPS and implements cookie consent but lacks explicit security headers and an incident response contact. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is consistent with the business profile, showing domain registration in 2020, matching the company's founding timeline. Overall, the site presents a trustworthy and professional digital presence with room for security enhancements. Strategically, Green Control should focus on strengthening its security posture by adding security headers, publishing an incident response policy, and considering a vulnerability disclosure mechanism. Enhancing privacy compliance transparency and maintaining up-to-date technical components will further solidify trust and operational resilience.

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 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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

Green Control operates in the renewable energy sector, primarily managing wind power plants. Its competitive advantage lies in its integration within the MICRONIX Group, providing access to technical expertise and financial resources. The business model centers on offering end-to-end services including development, technical operations, commercial management, and financing support. Revenue streams likely derive from service contracts with energy producers and investors. The target customers are energy asset owners seeking professional management to optimize performance and compliance. The company demonstrates growth potential through its extensive portfolio and cross-border operations in Europe. Partnerships with technology providers like Vestas and its parent group enhance its market credibility. The website's detailed references and quality policy indicate a mature operational approach and customer focus.

Security posture

The website exhibits a moderate to strong security posture with mandatory HTTPS and cookie consent mechanisms in place. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. No incident response or abuse contact information is provided, limiting transparency in security incident handling. The absence of a security.txt file or vulnerability disclosure policy reduces the opportunity for coordinated vulnerability reporting. No outdated or vulnerable libraries were detected in the HTML content. Overall, the security maturity is adequate for a corporate site but could be improved by adopting additional best practices and formalizing incident response communications.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish an incident response contact or page to improve transparency and readiness.
  3. Create and host a security.txt file to facilitate vulnerability disclosure.
  4. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  5. Enhance privacy compliance disclosures with detailed data retention and processing policies.

Technical notes

Notes

The website is built on WordPress 5.4.18, utilizing common plugins such as Yoast SEO and WP Performance Score Booster to optimize SEO and performance. It uses jQuery and Slick Carousel for interactive elements and integrates Google Tag Manager, Google Analytics, and Hotjar for analytics and user behavior tracking. The site loads resources over HTTPS, indicating good SSL configuration. DNS prefetching is used for performance optimization. The site is mobile responsive with good navigation clarity and content structure. However, the hosting provider is not explicitly identified, and no advanced frameworks beyond WordPress are detected. Performance is moderate, with potential for improvement by optimizing script loading and caching strategies. Accessibility features are basic but present. Overall, the technical implementation supports a professional and functional user experience.
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.
