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

STARKL is a well-established family gardening business operating since 1912, specializing in the cultivation and sale of plants suitable for the Czech climate. The company operates both physical garden centers and an e-commerce platform, serving customers primarily in the Czech Republic and neighboring EU countries. Their brand is recognized with the prestigious Superbrands award, indicating strong market presence and trust. Technically, the website uses a traditional tech stack with jQuery and Google Tag Manager, and it is well-optimized for mobile and SEO. Security measures include HTTPS and Google reCAPTCHA, but could be improved with additional security headers and explicit incident response policies. The absence of WHOIS data reduces transparency but does not negate the company's legitimacy given the rich content and certifications. Overall, the website is professional, secure, and compliant with GDPR, serving its target audience effectively.

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. 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

      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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

STARKL holds a strong market position as a family-owned gardening retailer with over a century of experience. Their business model combines brick-and-mortar garden centers with an online e-shop, targeting gardening enthusiasts and retail customers. The company leverages its long history and brand recognition to maintain customer trust and loyalty. Partnerships with industry associations and a professional website presence support their credibility. The company actively markets through social media and offers loyalty programs. Growth opportunities include expanding digital presence and enhancing customer engagement through improved online services.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and Google reCAPTCHA implemented to mitigate bot activity. However, the lack of visible security headers such as Content Security Policy or HSTS is a gap. No public security or incident response policies were found, which could impact transparency and readiness. The cookie consent mechanism aligns with GDPR requirements, indicating privacy awareness. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is adequate but could benefit from enhancements in header policies and published security documentation.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  4. Consider publishing a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  5. Improve contact information visibility, including verified company emails and phone numbers, to enhance trust and customer support.

Technical notes

Notes

The website uses a legacy but stable technology stack centered on jQuery and jQuery UI, supplemented by Google Tag Manager and reCAPTCHA for analytics and bot protection. The site is mobile optimized and SEO friendly with proper meta tags and canonical links. Performance is moderate, with asynchronous loading of scripts. No modern frameworks or CMS were detected, suggesting a custom or older platform. Hosting provider details are not evident. The site could benefit from modernization to improve performance and maintainability, including upgrading JavaScript libraries and adopting modern frontend frameworks.
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.
