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

Sky UK Limited operates a comprehensive telecommunications and media services website offering TV, broadband, and mobile phone packages primarily targeting UK residential and business customers. The website showcases a modern, professional design with clear navigation and extensive content about their products and services, including streaming devices like Sky Glass and Sky Stream puck. The company holds a strong market position as a leading UK telecommunications and media provider with a broad portfolio of entertainment and connectivity services. Technically, the website employs a modern tech stack including React (Next.js), Adobe DTM, Optimizely, and a consent management platform, ensuring good performance, mobile optimization, and accessibility. Security best practices are observed with HTTPS enforcement, security headers, and cookie consent mechanisms. However, no explicit security policy or incident response contact information is published, which could be improved. The security posture is strong with no detected vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with comprehensive privacy and cookie policies and GDPR compliance indicators. Business credibility is high based on professional content and trust signals, though the absence of WHOIS data slightly reduces confidence. Overall, the website presents a low-risk profile with strong digital maturity and compliance. Strategic recommendations include publishing a dedicated security policy, incident response contacts, and vulnerability disclosure information to enhance transparency and trust.

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

2 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.

    • 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

  2. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 UK Limited is positioned as a major player in the UK telecommunications and media sector, offering subscription-based TV, broadband, and mobile services. Their business model relies on bundled packages and streaming technology to attract and retain customers. The company leverages partnerships and subsidiaries such as Sky Group and business.sky.com to extend its market reach. Growth indicators include new product launches like Sky Glass Air TV and competitive broadband offerings. The company maintains a strong brand presence with consistent messaging and comprehensive customer support infrastructure.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented. The use of a consent management platform indicates attention to privacy compliance. No vulnerabilities or security incidents are evident from the analysis. However, the lack of a publicly available security policy and incident response contacts suggests room for improvement in transparency and preparedness. Compliance with GDPR is evident, but additional documentation such as a vulnerability disclosure policy or security.txt file would strengthen the security culture and incident readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet or exceed WCAG standards for broader inclusivity.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Key observations

  1. Website is fully accessible with rich content and professional design.
  2. Strong focus on UK market with localized content and country switcher.
  3. Comprehensive legal and privacy documentation present.
  4. Use of modern web technologies and consent management.
  5. No signs of phishing or malware detected.
  6. WHOIS data unavailable, which is unusual but not necessarily suspicious for a large brand.
Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering for performance optimization. It integrates multiple third-party services for analytics, consent management, and marketing, including Adobe DTM, Google Tag Manager, Optimizely, and Branch.io. The site is well-optimized for mobile devices and includes accessibility features such as skip links and ARIA labels. Performance is fast with efficient resource loading and caching strategies. No CMS is explicitly detected, suggesting a custom or proprietary content management solution. Hosting details are not explicitly available but likely involve enterprise-grade infrastructure given the scale and performance.
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.
