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.

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 leverages a subscription-based business model targeting residential customers in the UK and Republic of Ireland. Their revenue streams include TV subscriptions, broadband packages, mobile plans, and home insurance products. The company benefits from regulatory compliance, including FCA authorization for consumer credit, enhancing customer trust. Strategic partnerships with Samsung for device promotions and cinema partners like Vue expand their ecosystem. The company emphasizes customer service excellence and accessibility, supported by a comprehensive help and support infrastructure. Growth indicators include new product launches such as Sky Glass Air TV and expansion of live sports offerings. The partnership ecosystem and detailed legal disclosures reflect a mature operational approach and strong market presence.

Security posture

The security posture of Sky UK Limited's website is strong, with implementation of key security headers including HSTS with preload, Content Security Policy with restrictive directives, X-Frame-Options set to SAMEORIGIN, and X-Content-Type-Options set to nosniff. SSL certificates are valid and issued by a trusted CA with a 2048-bit key length. However, the absence of enabled TLS protocols (TLS 1.2 or higher) and lack of DNSSEC implementation represent areas for improvement. No explicit security policy or incident response information is publicly available, which could impact transparency. The website uses secure cookies with appropriate flags and has a consent management platform in place, supporting GDPR compliance. No known vulnerabilities such as Heartbleed or POODLE are present. Overall, the security maturity is good but could be enhanced by enabling modern TLS protocols and publishing security policies.

Recommendations

  1. Enable TLS 1.2 or higher protocols to ensure secure encrypted communications.
  2. Implement DNSSEC to protect against DNS spoofing and improve domain security.
  3. Publish a dedicated security policy and incident response page to increase transparency.
  4. Establish and publish a vulnerability disclosure program including a security.txt file.
  5. Regularly review and update Content Security Policy and cipher suites to maintain best practices.

Technical notes

Notes

The website is built on a modern technology stack including Next.js and React, hosted on Google Frontend infrastructure. It integrates multiple third-party services for analytics, marketing, and content delivery such as Adobe DTM, Optimizely, Dynatrace, Branch.io, and Brightcove. The use of Contentstack CMS facilitates content management. Performance is optimized with preloading of critical assets and responsive images. Accessibility features such as skip links and country switcher are implemented. SEO is supported by meta tags, canonical links, and structured navigation. However, the lack of enabled TLS protocols and absence of DNSSEC indicate technical debt in security infrastructure. The site is well-structured for scalability and user experience but should address these security gaps to mitigate risks.
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.
