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

SazeniOnline.cz is a Czech Republic based website dedicated to sports betting enthusiasts, including e-sports fans. It provides comprehensive reviews of online sportsbooks, betting tips, and educational content on betting strategies. The site operates primarily as an affiliate marketing platform, linking users to various betting providers with sponsored offers. Founded in 2020, it targets a niche market with consistent branding and good content quality. Technically, the site uses modern JavaScript frameworks, Swiper.js for UI components, and integrates Google Tag Manager and Seznam.cz tracking for analytics. The website is mobile optimized and SEO friendly but lacks some accessibility features. Security-wise, the site enforces HTTPS and uses affiliate link best practices but lacks visible security headers and formal privacy or cookie policies. WHOIS data is unavailable, which reduces domain trustworthiness, though the site appears professionally maintained. Overall, the site is a moderately trustworthy resource for Czech sports bettors but should improve privacy disclosures and security practices.

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

12 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 website holds a strong position in the Czech sports betting niche, leveraging affiliate marketing as its main revenue stream. It offers detailed sportsbook reviews, bonus information, and betting education, appealing to both novice and experienced bettors. The presence of multiple partner domains and social media channels indicates an active marketing ecosystem. The business model focuses on content-driven user acquisition and monetization through affiliate commissions. Growth potential exists through expanding content and improving compliance and security transparency. The lack of direct contact information and WHOIS data suggests a small-sized operation with limited public corporate disclosures.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is properly implemented, and affiliate links use rel="sponsored nofollow" attributes, which is a good practice. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS is a gap. No incident response or security policy information is provided, and no vulnerability disclosure or security.txt files are found. The site does not expose sensitive data or show signs of vulnerabilities in the analyzed content. Privacy compliance is minimal, with no visible privacy or cookie policies, which is a compliance risk under GDPR. Overall, the security maturity is adequate for a content site but requires enhancements to meet higher standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Publish contact information for security incidents and consider adding a security.txt file for vulnerability disclosures.
  4. Enhance accessibility features to improve usability for all users.
  5. Obtain and publish WHOIS and domain registration information to improve trust and transparency.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with reactive state management and Swiper.js for interactive sliders. It integrates Google Tag Manager and Seznam.cz tracking scripts for analytics and marketing. The site is mobile responsive and optimized for SEO with proper meta tags and structured data (JSON-LD). However, no CMS or hosting provider information is evident. Performance is moderate, with some opportunities for optimization. Accessibility is basic and could be improved. The lack of security headers and privacy disclosures indicates technical debt in compliance and security areas. Overall, the technical infrastructure supports the business model but requires enhancements for security and compliance.
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.
