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

Zerlina s.r.o. operates a small family ecological goat farm located in Rožnov pod Radhoštěm, Czech Republic. The business focuses on producing high-quality organic goat dairy products including fresh and aged cheeses, yogurts, kefir, and ice cream. Additionally, the farm offers agrotourism experiences, farm tours, and accommodation services, targeting families, individuals, and groups interested in sustainable farming and local gastronomy. The company positions itself as a trusted regional player with a strong emphasis on tradition and ecological sustainability. Technically, the website is built on WordPress with a modern tech stack including JavaScript libraries, Google reCAPTCHA for form security, and Google Analytics for visitor tracking. The site is well-optimized for mobile devices and provides a good user experience with clear navigation and professional design. Cookie consent and privacy policies are implemented in compliance with GDPR requirements. From a security perspective, the site uses HTTPS with a valid SSL certificate and integrates reCAPTCHA to protect forms. However, it lacks some recommended security headers which could enhance protection against common web threats. The absence of WHOIS registration data reduces domain trustworthiness, but the website content and business information appear legitimate and professional. Overall, Zerlina's website demonstrates a solid digital presence for a small ecological farm with good privacy compliance and user experience. Strategic improvements in security headers and domain registration transparency would further strengthen trust and security posture.

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

  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

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

Zerlina operates in the niche market of organic goat dairy products combined with agrotourism and hospitality services. Their competitive advantage lies in their authentic family-run farm approach, ecological certification, and diversified offerings including farm tours and accommodation. Revenue streams likely include direct product sales, tourism experiences, and lodging. The target customers are eco-conscious consumers, families, and tourists seeking rural experiences. The partnership ecosystem includes regional tourism boards and organic certification bodies, enhancing market credibility. Growth potential exists in expanding agrotourism and online sales channels. The company maintains a consistent brand image emphasizing tradition and sustainability.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and Google reCAPTCHA protecting forms. Cookie consent management is implemented via a reputable GDPR plugin. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could expose the site to clickjacking or content injection attacks. No visible vulnerabilities or exposed sensitive data were detected. The absence of a security.txt file or incident response contact limits transparency for vulnerability reporting. Overall, the security posture is adequate for a small business but could be improved to align with best practices and compliance standards.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Ensure regular updates of WordPress core, themes, and plugins to mitigate vulnerabilities.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  4. Verify and publish WHOIS domain registration data to improve domain legitimacy and trust.
  5. Conduct periodic security audits and penetration testing to proactively identify and remediate risks.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including JavaScript and CSS optimizations. It uses popular plugins such as RevSlider for visual content and Complianz for GDPR cookie management. Google Maps API integration supports location display. The site is mobile responsive with good SEO meta tags and structured data (JSON-LD) for enhanced search engine understanding. Performance is moderate, with caching and minification applied. Accessibility features are basic but present. Technical debt appears low, though security header implementation is lacking. Hosting provider details are not disclosed, limiting infrastructure assessment.
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.
