ZOFI is a Czech Republic-based company specializing in facade insulation services and materials, operating since 2006 with a solid market presence and over 750 completed projects. The company offers a comprehensive range of services including consulting, project planning, material sales via an e-commerce platform, and assistance with government subsidies. Their website reflects a professional and consistent brand image targeting homeowners and property managers seeking quality facade insulation solutions. Technically, the website employs modern web technologies, including Google Tag Manager, Google Analytics, reCAPTCHA, and New Relic monitoring, ensuring good performance and user experience across devices. Security measures such as HTTPS, cookie consent with granular categories, and bot protection are implemented, although explicit security policies and incident response contacts are not publicly available.

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

8 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

      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. 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

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

ZOFI operates in the Real Estate sector focusing on facade insulation, combining service delivery with product sales through an integrated e-commerce platform. Their competitive advantage lies in their long-standing experience since 2006, professional service quality, and comprehensive offerings including subsidy assistance. The company targets residential and commercial property owners in the Czech Republic. Their digital presence is supported by active social media channels and a well-structured website, enhancing customer engagement and trust. Partnerships include their own e-shop and the web development agency BlueGhost. The business model is a hybrid of service provision and direct product sales, positioning them as a key player in the local facade insulation market.

Security posture

The website demonstrates a good security posture with enforced HTTPS, use of Google reCAPTCHA v3 to mitigate automated abuse, and a cookie consent mechanism that respects user privacy preferences. Monitoring and performance tracking are enabled via New Relic, Google Analytics, and Hotjar, providing visibility into site health and user behavior. However, the absence of publicly accessible security policies, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers are implied but not explicitly confirmed in the HTML. Overall, the site is secure for typical user interactions but would benefit from enhanced security documentation and formal incident response channels.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve transparency and compliance.
  2. Implement and publicly disclose a security policy and incident response contact information.
  3. Add a security.txt file or vulnerability disclosure page to encourage responsible reporting of security issues.
  4. Enhance security headers such as Content-Security-Policy and X-Frame-Options to strengthen protection against common web attacks.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Google Analytics (including GA4), Google reCAPTCHA v3, and New Relic for performance and error monitoring. The frontend appears to be built with a custom or modern JavaScript framework, supported by CSS bundles and optimized images. The site is mobile responsive with good navigation clarity and SEO optimization through meta tags and Open Graph descriptions. Performance is moderate with asynchronous loading of analytics and tracking scripts. Accessibility features are basic but present. Hosting details are not explicitly available, but the site uses HTTPS with a valid SSL certificate. Overall, the technical implementation supports a professional and user-friendly experience with room for improvement in accessibility and security header configurations.
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.
