Risk levelLow

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

Energy Domy is a Czech construction company specializing in building practical bungalows, modern houses, and luxury villas using the unique Durisol masonry. With over 30 years of experience, the company positions itself as a provider of beautiful homes with lasting visual value. The website is professionally designed using Drupal 10 CMS and integrates modern marketing and analytics tools such as Microsoft Clarity, Facebook Pixel, and Google Tag Manager. Cookie consent is managed via Cookiebot, indicating some level of GDPR compliance awareness. However, the absence of a visible privacy policy and terms of service on the homepage limits full compliance transparency. Security posture is moderate with HTTPS implied but lacking explicit security headers and incident response information. WHOIS data is unavailable, which reduces domain trustworthiness and raises questions about domain registration legitimacy. Overall, the website is functional and professional but would benefit from enhanced transparency and security practices.

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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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-efficient construction sector, targeting customers interested in durable and modern homes in the Czech Republic. Its business model focuses on construction services using specialized materials like Durisol. The website content and branding are consistent and professional, supporting a medium-sized enterprise market position. The lack of publicly available WHOIS data and contact information may impact customer trust and regulatory compliance. The company leverages common digital marketing and analytics tools but does not display certifications or detailed business registrations on the site. There is no evidence of partnerships or subsidiaries from the website content provided.

Security posture

The website uses HTTPS and cookie consent mechanisms, which are positive security indicators. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No security.txt or vulnerability disclosure policy is present, and no incident response contact channels are provided. The use of multiple third-party scripts increases the attack surface and requires regular auditing. Overall, the security posture is moderate but could be significantly improved by implementing best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Add security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against web vulnerabilities.
  3. Publish security incident response contact information and consider adding a security.txt file for vulnerability disclosure.
  4. Verify and publish WHOIS domain registration details to improve domain legitimacy and trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built on Drupal 10 CMS with Bootstrap 5 for responsive design, and uses popular libraries such as Slick Carousel and Plyr for UI components. It integrates marketing and analytics tools including Microsoft Clarity, Facebook Pixel, and Google Tag Manager. The site is mobile optimized and SEO friendly with proper meta tags and canonical URLs. Performance is moderate, likely influenced by multiple external scripts. Accessibility features are basic but present. Hosting provider and SSL configuration details are not explicitly available from the provided data. There is an opportunity to improve technical security configurations and enhance privacy transparency.
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.
