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

Sparkys KLUB is a loyalty program website operated by PragueBest s.r.o., targeting customers of Sparkys toy stores in the Czech Republic. The site offers a points-based rewards system ('Kačky'), birthday and name day bonuses, club pricing, and electronic receipt management, aiming to enhance customer retention and engagement. The website is professionally designed with clear navigation and mobile optimization, supporting user registration and login with Google reCAPTCHA protection. Technically, it employs modern web technologies including Google Tag Manager, Foxentry address validation, and a cookie consent management system compliant with GDPR. Security posture is solid with HTTPS enforced and spam protection, though explicit security headers are not detected and no incident response or vulnerability disclosure information is provided. WHOIS data is unavailable, which slightly reduces domain trustworthiness, but the website content and contact details appear legitimate and consistent with a small retail business. Overall, the site demonstrates a good balance of business functionality, technical implementation, and privacy compliance, suitable for its retail loyalty program purpose.

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. 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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 website serves as a digital loyalty platform for Sparkys toy stores, operated by PragueBest s.r.o., a small retail entity in the Czech Republic. Its business model focuses on customer retention through rewards and personalized offers. The presence of social media links and a cookie consent mechanism indicates awareness of modern marketing and privacy requirements. The lack of WHOIS transparency is a minor concern but does not detract significantly from the business credibility given the clear contact information and professional presentation. The site likely generates revenue indirectly by increasing customer loyalty and sales at physical and online Sparkys stores. No direct e-commerce functionality is evident on this site, suggesting it complements the main sales channels. The company appears to maintain a focused niche in retail toys with a loyalty program as a competitive advantage.

Security posture

The website enforces HTTPS and integrates Google reCAPTCHA v3 to protect user forms from spam and abuse. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which are recommended to enhance security posture. There is no visible security policy or incident response contact information, which could be improved to demonstrate security maturity. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of WHOIS data reduces transparency but does not directly impact technical security. Overall, the security posture is good but could be strengthened by adding security headers and formal security documentation.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options, X-XSS-Protection) to improve defense-in-depth.
  2. Publish a dedicated security policy and incident response contact information to enhance trust and compliance.
  3. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain transparency by ensuring WHOIS data is available or justified if privacy protection is used.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager for analytics and marketing, Google reCAPTCHA v3 for bot protection, Foxentry for address validation, and a cookie consent management system compliant with GDPR. It loads asynchronously to improve performance and includes mobile optimization and accessibility features at a basic level. The site does not appear to use a common CMS or hosting provider identifiable from the data. Performance is moderate with room for improvement in SEO and accessibility. The presence of service workers (Workbox) suggests some level of progressive web app capabilities. Overall, the technical infrastructure supports the business needs effectively but could benefit from enhanced SEO and accessibility optimizations.
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.
