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

8 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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 leverages its affiliation with MAFRA, a.s. to maintain a strong market position in Czech digital media. Its business model combines free content supported by targeted advertising and a subscription-based premium tier. The partnership ecosystem includes major advertising and tracking providers such as Criteo, Gemius, and Adform. The site targets a broad demographic interested in influencer news, capitalizing on the growing social media influencer market. Growth indicators include integration with multiple ad networks and consent management platforms, reflecting compliance with privacy regulations and monetization strategies.

Security posture

Antiyoutuber.cz demonstrates a solid security posture with enforced HTTPS and implementation of a consent management platform to comply with GDPR requirements. However, the absence of explicit security headers and publicly available security policies or incident response information indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site’s extensive use of third-party scripts and trackers necessitates ongoing monitoring to mitigate privacy and security risks. Overall, the security maturity is moderate with recommendations to enhance header configurations and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Publish clear privacy and security policies on the website to improve transparency and user trust.
  3. Provide explicit contact information for privacy and security inquiries, including a designated Data Protection Officer if applicable.
  4. Regularly audit third-party scripts and trackers to ensure compliance with privacy regulations and minimize security risks.
  5. Enhance accessibility and mobile optimization to improve user experience and compliance with standards.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and SDKs for analytics, advertising, and consent management, including Google Analytics, Google Tag Manager, Didomi CMP, Gemius, Marfeel SDK, and CPEX advertising packages. The HTML structure is well-formed with appropriate meta tags for SEO and social media sharing (Open Graph). Performance is moderate with asynchronous loading of scripts to optimize page load times. Mobile optimization is basic but functional. No CMS or hosting provider details were explicitly detected. The site could benefit from improved accessibility features and enhanced SEO practices.
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.
