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

Plinko Casino is a Slovak-focused online gambling website specializing in the Plinko game, offering real money play, bonuses, demo versions, and a mobile app. The site targets Slovak players but is part of a broader international network with sister sites in multiple countries. The business is relatively new, established in 2024, and positions itself as a trusted provider with certified RNG and responsible gaming information. Technically, the site uses modern web standards, Cloudflare for DNS and CDN, and implements HTTPS with security headers, ensuring a secure and performant user experience. However, it lacks some privacy compliance features such as a cookie consent mechanism and publicly available security policies. Overall, the site is professional and content-rich, with good SEO and mobile optimization, but could improve transparency and privacy compliance to enhance trust and regulatory adherence.

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

9 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. 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 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 operates in the online gambling sector, focusing on the Plinko game, a popular game of chance. It leverages a multi-language strategy to reach various European and international markets, indicating a scalable business model. Revenue streams likely include affiliate commissions from partner casinos and direct player deposits. The presence of detailed guides, bonus offers, and demo games suggests a user engagement strategy aimed at player acquisition and retention. The company maintains active social media channels to support marketing and community building. The business is small-sized and relatively new, with no public parent or subsidiary companies. Its competitive advantage lies in localized content and a broad network of related domains targeting different markets.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, Cloudflare protection, and standard security headers implemented. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a public security policy, incident response plan, or vulnerability disclosure program indicates room for improvement in transparency and preparedness. The site does not provide explicit contact channels for security incidents, which could hinder timely response to threats. Privacy compliance is partial, lacking cookie consent mechanisms, which is a notable gap given EU regulations. Overall, the security posture is good but could be enhanced by formalizing policies and improving user privacy controls.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and ePrivacy Directive requirements.
  2. Publish a comprehensive security policy and incident response plan accessible to users.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide contact information for a Data Protection Officer or security team to improve trust and compliance.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all users.

Technical notes

Notes

The website is built using standard HTML5, CSS3, and JavaScript technologies, with JSON-LD structured data for SEO enhancement. It uses Cloudflare for DNS and CDN services, which improves security and performance. The site is mobile-optimized and includes responsive design elements. Performance is moderate, with deferred loading of some scripts and lazy loading of iframe content. No CMS or backend technology is explicitly detected, suggesting a static or custom-built site. The technical implementation is modern and follows best practices, though accessibility could be improved. No outdated or vulnerable libraries were found, indicating low technical debt and good maintenance.
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.
