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

ČAK CZ s.r.o. is a small Czech construction and trading company specializing in water management, engineering networks, transport construction, and earthworks. Founded in 1998 and based in Kroměříž, the company serves municipalities, private companies, and individuals, emphasizing quality and compliance with ISO standards. Their website reflects a professional presence with detailed business descriptions and references to certifications but lacks modern privacy and security features. Technically, the site uses legacy JavaScript libraries and lacks HTTPS enforcement, which poses security risks. No privacy or cookie policies are present, indicating compliance gaps with GDPR. Overall, the security posture is moderate but requires improvements in HTTPS adoption and security headers. The website is safe for general audiences and does not contain adult or questionable content.

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

9 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

  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 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

      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';…

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 holds a stable market position as a regional construction firm with over two decades of experience. Their business model focuses on infrastructure and civil engineering projects, targeting municipalities and private sector clients. The presence of ISO certifications and positive client references supports credibility. The website's lack of social media and modern marketing tools suggests a traditional business approach. No evident partnerships or subsidiaries were identified beyond the design partner Traxart Graphics. Growth indicators are moderate, with a focus on quality and client satisfaction.

Security posture

The security maturity level is basic. The site lacks HTTPS enforcement and uses an outdated jQuery version loaded over HTTP, exposing it to mixed content vulnerabilities. No security headers were detected, and no incident response or vulnerability disclosure information is provided. The company demonstrates awareness of quality and safety standards through ISO certifications but does not extend this rigor to digital security practices. GDPR compliance is weak due to missing privacy and cookie policies. The absence of contact forms reduces attack surface but also limits user engagement.

Recommendations

  1. Implement HTTPS across the entire website and update all external resources to HTTPS to eliminate mixed content issues.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  4. Provide clear incident response contact information to facilitate vulnerability reporting and improve security culture.
  5. Modernize the technology stack by updating JavaScript libraries and improving mobile responsiveness and accessibility.

Technical notes

Notes

The website is built with standard HTML, CSS, and JavaScript, including legacy libraries like MooTools and an outdated jQuery version loaded insecurely. Google Fonts are used for typography. The site lacks a CMS or modern frameworks, indicating a static or custom-built site. Performance is moderate with no explicit optimization noted. Mobile optimization and accessibility are basic, with no ARIA roles or advanced features detected. SEO is basic, relying on meta tags but lacking structured data or Open Graph tags. Hosting provider details are not available from the data. Overall, the technical infrastructure is functional but dated, with modernization opportunities to improve security, performance, and 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.
