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

Družstevní závody Dražice is a traditional Czech manufacturer specializing in water heaters, boilers, and hot water storage tanks. Established in 1998, the company positions itself as a quality and longevity-focused producer within the energy sector. The website reflects a medium-sized enterprise with a professional online presence, targeting general consumers and businesses interested in energy-efficient water heating solutions. Technically, the site is built on Joomla CMS and leverages modern web technologies including jQuery, Bootstrap, and multiple marketing and analytics tools such as Google Analytics and Facebook Pixel. The site is mobile-optimized and performs moderately well. Security-wise, the website enforces HTTPS and includes a cookie consent mechanism, but lacks explicit security headers and published privacy or terms of service documents. No direct contact information or security incident channels are visible, which could be improved to enhance trust and compliance. Overall, the domain's long age and consistent WHOIS data support the legitimacy of the business. Strategic improvements in privacy disclosures, security headers, and contact transparency are recommended to strengthen the security posture 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

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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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: Google Analytics, Facebook, YouTube, Google APIs, Google Ads

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

  2. 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 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';…
  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 manufacturing sector, focusing on water heating products. Its market position is that of a traditional, quality-oriented manufacturer with a stable presence since 1998. The business model centers on product manufacturing and sales, targeting both residential and commercial customers. The website's use of multiple tracking and retargeting services indicates active marketing efforts. However, the absence of clear contact details and privacy policies may limit customer trust and regulatory compliance. There is no evidence of partnerships or subsidiaries from the website content or WHOIS data. The company appears to maintain consistent branding and content quality, supporting a medium-sized enterprise profile within the Czech Republic.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented, reflecting awareness of privacy regulations. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No vulnerability disclosures or security.txt files are present, and no direct security contact channels are provided, which may hinder incident response readiness. The extensive use of third-party tracking scripts increases the attack surface and privacy risks. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate but could be significantly improved by adopting best practices in security headers, transparency, and incident response.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file and provide clear contact information for security incidents.
  4. Review and minimize third-party tracking scripts to reduce privacy risks and improve performance.
  5. Enhance accessibility features to improve usability for all users.

Technical notes

Notes

The website is built on Joomla CMS with a tech stack including jQuery and Bootstrap, indicating a mature but somewhat traditional technology base. It integrates multiple analytics and marketing tools, including Google Analytics, Google Tag Manager, Facebook Pixel, and Adform retargeting. The site is mobile-optimized and uses modern fonts and responsive design. Hosting appears to be via a Czech registrar and likely local hosting provider. Performance is moderate, with no critical technical issues detected. Opportunities exist to modernize the tech stack, improve security headers, and optimize third-party script usage to enhance speed and security.
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.
