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

START Zelený s.r.o. is a small Czech Republic based company specializing in construction work, sales of building materials, and garden and forest machinery. The company targets local customers primarily in the Kraj Vysočina region. The website is built on the Wix platform, leveraging Wix Thunderbolt and standard web technologies, providing a moderate level of performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and formal privacy or cookie policies. The absence of WHOIS data due to privacy protection limits transparency but does not contradict the business legitimacy indicated by the website content and structured data. Overall, the site presents a professional and trustworthy image for a small regional business.

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

7 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      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 operates in the construction and materials sector, offering both services and product sales. Its business model is focused on local/regional market penetration with direct customer engagement. The website content and structured data confirm the company's legal identity and contact details, supporting business credibility. No partnerships or subsidiaries are identified from the website content. The lack of privacy and security policies suggests room for improvement in compliance and customer trust. The company appears to maintain a straightforward business approach without extensive digital marketing or analytics integration.

Security posture

The website uses HTTPS, ensuring encrypted communication. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. No evidence of vulnerable libraries or exposed sensitive data was found. The site does not provide incident response or vulnerability disclosure information, which is a gap in security maturity. Cookie handling scripts are present but no explicit consent mechanism or cookie policy is implemented, indicating partial GDPR compliance. Overall, the security posture is moderate but could be significantly improved with standard best practices and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with user consent mechanisms to improve GDPR compliance.
  2. Add essential security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web vulnerabilities.
  3. Provide clear incident response and vulnerability disclosure information to build trust and readiness for security events.
  4. Conduct regular audits of third-party scripts and dependencies to identify and mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built on the Wix platform using Wix Thunderbolt framework and standard polyfills for browser compatibility. It uses Google Fonts for typography and loads resources from Wix static content delivery domains. The site is mobile optimized and uses modern CSS and JavaScript techniques. Performance is moderate, typical for Wix-hosted sites. No custom analytics or tracking services were detected. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. The site structure and meta tags support basic SEO but could be improved for better discoverability and accessibility.
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.
