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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain:

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

Sky Group holds a dominant position in the European media and telecommunications sector, leveraging its parent company Comcast NBCUniversal's resources. Its business model focuses on direct consumer engagement through broadband and entertainment services, including premium sports content and original productions. The company targets a wide demographic across multiple European countries, with localized site versions. Strategic partnerships and integrations with major technology and marketing platforms enhance its operational capabilities. The presence of comprehensive privacy and cookie policies indicates a mature approach to regulatory compliance. Growth indicators include recent launches of high-speed broadband services and significant sports broadcasting deals. The company maintains a strong brand reputation and digital ecosystem, supported by verified social media channels and corporate transparency.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of a GDPR-compliant consent management platform, and no visible exposure of sensitive data. The integration of Adobe Launch and Sourcepoint indicates controlled data collection and user consent management. However, the absence of a publicly accessible security policy, incident response plan, or vulnerability disclosure program limits transparency and preparedness communication. Security headers are implied but not explicitly confirmed in the HTML content. No vulnerabilities or malicious content were detected. To enhance security maturity, publishing explicit security documentation and providing clear incident contact channels are recommended. Overall, the site balances user privacy and security well but could improve in incident readiness and disclosure transparency.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website to improve transparency and user trust.
  2. Implement and publicly expose a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Explicitly configure and document all recommended security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear and verified contact information for security incidents, including dedicated security or abuse email addresses.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use and maintain up-to-date software versions.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js frameworks, supported by Contentstack CMS for content management. It integrates Adobe Launch for marketing and analytics and Sourcepoint for privacy and consent management, reflecting a high level of digital maturity. The site is well-optimized for performance and mobile responsiveness, with good accessibility features. The use of preloading for images and scripts indicates performance optimization efforts. No technical debt or legacy technologies were detected. Hosting details are not explicitly disclosed but the infrastructure supports fast loading and reliable delivery. Opportunities exist to enhance security header configurations and increase transparency around security 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.
