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

Webhry.cz is an online gaming portal operated by Sector s.r.o., targeting Czech and Slovak audiences with a wide variety of free online games including flash, HTML5, and Unity-based titles. The site offers categorized game listings, user account features, and integrates advertising as its primary revenue model. The technical infrastructure leverages common web technologies such as jQuery, Google Analytics, and Google Adsense, with a consent management platform for cookie compliance. While the site is accessible over HTTPS and includes basic security practices, it uses outdated JavaScript libraries and lacks visible privacy and terms of service pages, which are areas for improvement. The absence of WHOIS data limits domain trust verification, but the presence of company contact information and consistent branding supports legitimacy. Overall, the site provides a good user experience with family-friendly content and moderate technical maturity.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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 · found on this site
  • 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 business operates in the media sector, focusing on online entertainment through free gaming content. Its market position is regional, serving Czech and Slovak users. The business model relies on advertising revenue, supported by Google Adsense and tracking via Google Analytics and Quantcast. The company maintains partnerships with sector.sk for user authentication and content management. Growth potential exists in expanding mobile optimization and enhancing privacy compliance. The lack of visible privacy policies and outdated libraries may impact user trust and regulatory compliance. The company appears to have a moderate size and professional presence but could benefit from clearer business disclosures and security certifications.

Security posture

The website demonstrates a basic to moderate security posture with HTTPS enabled and consent management for cookies. However, the use of outdated jQuery versions introduces potential vulnerabilities. There is no evidence of advanced security headers like CSP or HSTS, nor is there a security.txt or vulnerability disclosure page. The site does not expose sensitive data in the HTML, but mixed content scripts and lack of modern security practices reduce the overall security score. Incident response and security policy information are absent, indicating limited transparency in security governance. Improvements in updating libraries, implementing security headers, and publishing security policies are recommended to enhance security maturity.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Publish clear and accessible privacy and cookie policies to improve GDPR compliance and user trust.
  3. Implement Content Security Policy (CSP) and other security headers to strengthen defense against XSS and related attacks.
  4. Create and publish a security.txt file and vulnerability disclosure policy to facilitate responsible security reporting.
  5. Ensure all external resources are loaded over HTTPS to avoid mixed content issues and improve security posture.

Technical notes

Notes

The website uses a traditional web stack with HTML5, CSS, and JavaScript, including multiple versions of jQuery (1.3.1 and 1.8.1), which are outdated and pose security risks. It integrates Google Analytics, Google Adsense, and Quantcast for analytics and advertising, along with a consent management platform for cookie compliance. The site is moderately optimized for mobile devices but could improve responsiveness and accessibility. SEO practices are basic with meta tags and Open Graph data present. Hosting details are not explicit, but partner domain sector.sk is heavily integrated. Performance is moderate, with some legacy scripts potentially impacting load times. Overall, the technical implementation is functional but would benefit from modernization and security hardening.
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.
