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

Mostbet Česká republika is an online gambling platform licensed under Curaçao jurisdiction, offering a wide range of services including sports betting, online casino games, poker, and esports betting. The platform targets Czech players with localized content, multiple language support, and generous bonus programs. The business model revolves around attracting and retaining players through bonuses, loyalty programs, and mobile applications for Android and iOS. The website is professionally designed, mobile-optimized, and provides clear navigation and contact information, supporting a moderate to high level of business credibility. Technically, the website is built on WordPress with modern technologies such as FontAwesome and Google Tag Manager for analytics. It supports mobile platforms well and includes structured data for SEO. Performance is moderate with good accessibility and SEO optimization. Security posture is solid with HTTPS enabled and no exposed sensitive data, though some security headers are missing and no explicit security or incident response policies are published. The domain WHOIS data is limited due to unsupported TLD WHOIS and privacy protection, but the domain expiry date is valid and recent, supporting legitimacy. No WAF or blocking mechanisms were detected, and the site content is fully accessible. Privacy compliance is basic with no explicit privacy or cookie policies found, which is a notable gap. Overall, Mostbet Czech Republic presents a legitimate and professional gambling service with room for improvement in privacy compliance and security header implementation. Strategic recommendations include publishing comprehensive privacy and cookie policies, enhancing security headers, and establishing clear incident response contacts to improve trust and compliance.

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

10 findings rated critical or high. Fix these first.

  1. 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

  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

      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';…

  3. 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

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

Mostbet operates in the online gambling sector, focusing on the Czech market with a licensed offering under Curaçao regulation. The company leverages a multi-service platform including sportsbook, casino, poker, and esports betting, supported by mobile apps. Its competitive advantage lies in a broad bonus program, localized language support, and a wide selection of games from certified providers. Revenue streams likely include betting margins, casino house edge, and possibly affiliate marketing. The presence of multiple payment methods including cryptocurrencies indicates a modern payment ecosystem. The company maintains active social media presence and customer support channels, indicating a mature operational model. Growth indicators include continuous content updates and mobile app promotion. Partnerships with related domains and certified providers strengthen its market position.

Security posture

The website demonstrates a good security posture with mandatory HTTPS encryption and no visible exposure of sensitive data. Use of Google Tag Manager is standard for analytics but requires careful configuration to avoid privacy leaks. Missing security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represent areas for improvement to mitigate clickjacking, MIME sniffing, and cross-site scripting risks. No vulnerability disclosures or incident response contacts are published, which limits transparency and readiness perception. The platform uses certified payment systems and cryptographic protocols as claimed, enhancing transactional security. Overall, the security maturity is moderate but can be enhanced by adopting best practices in HTTP headers and publishing security policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to comply with privacy regulations.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and publish an incident response policy with dedicated security contact channels.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks.

Technical notes

Notes

The website is built on WordPress CMS with modern front-end technologies including FontAwesome icons and Bootstrap components for responsive design. Google Tag Manager is used for analytics and marketing tracking. The site is mobile optimized with dedicated Android and iOS applications promoted. Performance is moderate, with good SEO metadata and structured data (JSON-LD) for enhanced search engine visibility. Accessibility features are present but could be further improved. Hosting provider details are not explicitly found. The domain uses a TLD with limited WHOIS support, and privacy protection is enabled. Overall, the technical infrastructure supports a professional gambling platform but could benefit from enhanced security headers and privacy compliance mechanisms.
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.
