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

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

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 occupies a niche in the children's sports education sector, focusing on winter activities. Its business model is service-oriented, delivering educational sports programs to families and schools. The presence of partner organizations like Kooperativa and FTVS UK suggests strategic collaborations. The domain age aligns with the company's recent founding in 2024, indicating a new but well-prepared market entry. The website's detailed FAQs, downloadable resources, and testimonials indicate a customer-centric approach and a focus on building trust and transparency.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is noted. There is no visible incident response or vulnerability disclosure information, which could be enhanced to improve security maturity. Overall, the security posture is good but could benefit from additional hardening and transparency measures.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-XSS-Protection) to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance contact information visibility by including verified company emails and phone numbers for support and security reporting.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website leverages modern JavaScript modules, Swiper.js for sliders, GSAP for animations, and Google Tag Manager for analytics. It uses CookieScript for cookie consent management, indicating compliance with privacy regulations. Hosting and domain registration are managed by WEDOS, a reputable Czech provider. The site is mobile-optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with potential for optimization in loading times. Accessibility features are present but could be further enhanced. No CMS was explicitly detected, suggesting a custom or static site architecture.
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.
