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

6 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

    • 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

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

Skylink holds a strong market position in the Czech media and telecommunications sector, leveraging Canal+ Luxembourg's brand and resources. Its business model combines subscription TV services with hardware sales and installation, appealing to a broad consumer base. The company maintains active partnerships and service portals to enhance customer experience. The presence of multiple social media channels and newsletters indicates a mature marketing strategy. Despite the lack of public WHOIS data, the website's branding and content strongly support its legitimacy and operational scale.

Security posture

The website enforces HTTPS and employs cookie consent mechanisms, reflecting good baseline security and privacy practices. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure information suggests room for improvement in transparency and security maturity. No critical vulnerabilities or exposed sensitive data were detected in the content. The site would benefit from implementing security headers and publishing a security.txt file to enhance trust and incident readiness.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Improve accessibility features to meet higher standards for users with disabilities.
  5. Enhance transparency by providing WHOIS or domain registration information if possible.

Technical notes

Notes

The website is built on a modern technology stack including Google Tag Manager for analytics and marketing, Cookiebot for GDPR-compliant cookie management, and a proprietary CMS platform (ISSA). The site is mobile responsive and optimized for performance with bundled CSS and JS assets. External integrations include social media links and streaming portals. While performance is moderate, there is potential for improvement in accessibility and SEO. The absence of visible hosting provider information limits full infrastructure assessment.
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.
