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

FantasyLiga.cz is a Czech Republic-based fantasy sports platform allowing users to create their own teams and compete with other fans. The website uses modern web technologies such as React and Next.js, hosted on AWS infrastructure, and integrates Google Analytics for user behavior tracking. The site is accessible without any WAF or security challenge blocking. However, it lacks visible privacy, cookie, and terms of service policies, which are important for compliance and user trust. Security headers are not detected, indicating room for improvement in security posture. The domain registration data is consistent and appropriate for the business age, supporting legitimacy.

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

11 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 platform targets general sports fans interested in fantasy leagues, primarily in the Czech Republic. The business model revolves around user engagement through fantasy sports competitions. The site shows consistent branding and a professional design but lacks explicit business contact details and compliance documentation. The use of AWS hosting and Google Analytics indicates a moderate level of digital maturity. No partnerships or subsidiaries are identified from the data provided.

Security posture

The website enforces HTTPS, which is a critical security baseline. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosures or incident response contacts are provided, which could hinder timely security issue reporting and resolution. The lack of privacy and cookie policies also indicates potential GDPR compliance gaps. Overall, the security posture is moderate but requires enhancements to meet best practices.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear contact information for security incidents and general inquiries.
  4. Introduce a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit and update third-party libraries and tracking tools to minimize vulnerabilities.

Technical notes

Notes

The website is built using a modern React and Next.js stack with Material-UI for styling, ensuring a responsive and user-friendly interface. Hosting on AWS provides scalability and reliability. Google Analytics is integrated for tracking, but no advanced SEO or accessibility features are evident from the provided data. Performance is moderate with asynchronous loading of scripts. The site lacks some technical security best practices such as security headers and explicit privacy compliance mechanisms. Overall, the technical infrastructure is solid but can benefit from enhanced security and compliance features.
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.
