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

TZÚS GROUP is a Czech association of three established testing and certification organizations specializing in construction product conformity assessment and fire safety. The group employs nearly 300 professionals and serves manufacturers, importers, designers, and public administration with comprehensive testing and certification services. The website is professionally designed, mobile-optimized, and includes GDPR-compliant cookie consent mechanisms. However, the absence of WHOIS data and lack of privacy policy and terms of service pages represent gaps in transparency and compliance. Technically, the site uses Bootstrap and jQuery with CSRF-protected forms but lacks visible security headers. Overall, the digital maturity is moderate with room for improvement in security and compliance documentation.

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

5 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 APIs

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

  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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 holds a strong market position as the largest testing and certification entity in the Czech Republic's construction sector. Its business model focuses on providing independent testing, certification, and technical support services. The group targets a broad audience including manufacturers, importers, and public authorities. Revenue is stable with over 10 million EUR annually. The partnership ecosystem includes three main entities with dedicated websites. The company demonstrates consistent branding and professional content but lacks published certifications or security policies on the website.

Security posture

The website demonstrates basic security hygiene with HTTPS (assumed), CSRF protection on forms, and GDPR cookie consent. However, no security headers were detected, and no incident response or vulnerability disclosure information is published. The missing WHOIS data raises concerns about domain registration transparency. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is moderate but could be significantly improved by adding security headers, publishing privacy and security policies, and clarifying incident response procedures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and transparency.
  2. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  3. Clarify domain registration details or ensure WHOIS data is publicly available to enhance trust.
  4. Add explicit incident response and vulnerability disclosure contact information to demonstrate security readiness.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses Bootstrap 3.3.7 and jQuery 1.11.3, which are somewhat outdated but still functional. The site is mobile responsive and includes CSRF tokens in forms, indicating attention to security in form submissions. Performance is moderate with external CDN usage for libraries. No CMS or hosting provider information was detected. The site lacks modern security headers and comprehensive SEO metadata. Cookie consent is implemented with detailed categories, reflecting GDPR awareness. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security 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.
